Ready to Leave Consumer Resin 3D Printers Behind? Here Are the Top Pro Printers for Business & Light Manufacturing

The Form 4 is an LCD printer (also called masked SLA) built around what Formlabs calls its Low Force Display print engine — a backlight unit of 60 high-power LEDs and collimating lenses that cures a full layer at once, so print time stays the same whether the platform holds one part or a full build. Maximum speed is 100 mm per hour, and Formlabs says most jobs finish in under two hours, a claim it bases on an 80th-percentile print height of 53 mm at a 100-micron layer. Accuracy is quoted as ±0.15% XY dimensional tolerance for 1 – 30 mm features, with a 50-micron pixel and pre-tuned anti-aliasing for sub-pixel detail. Formlabs cites an independently tested 98.7% print success rate. A 5-megapixel onboard camera handles remote monitoring, print history, and timelapses, and can be disabled, covered, or removed outright — worth knowing if you print under NDA.

Materials run to 23 Formlabs resins spanning rigid, tough, general purpose, flame retardant, silicone, elastic, ceramic, and castable grades, plus an optional Open Material Mode ($875 per printer) for any third-party 405 nm photopolymer. Biocompatible resins are not available on the standard Form 4; that requires the Form 4B. Print preparation runs through PreForm, which is free.

Post-processing uses Form Wash and Form Cure, and the complete package bundles both along with a solvent pump and a three-year service plan. Form Wash agitates parts in solvent — Formlabs recommends IPA, with TPM and its own Resin Washing Solution also compatible — then lifts them out automatically to air dry, with adjustable platform mounts and a variable solvent fill so small jobs don’t need a full bath. Form Cure combines a 48-LED array with convective heating, reaching 60 °C in a minute and topping out at 100 °C, at 14.5 mW/cm² irradiance. Its 235 mm glass turntable takes a full-size Form 4 build. General-purpose resins cure in 60 seconds, engineering resins in under 15 minutes, which is how Formlabs gets to its claim of print to finished part in as little as 11 minutes.

There’s also a Form 4L version with build volume 4.6-times larger than the Form 4 that we cover below.

Raise3D positions the DF2+ as a “true DLP” machine — its shorthand for projector-based DLP built with industrial optical components rather than an LCD masking screen. The optical path uses Texas Instruments industrial-grade DMD chips and Schott optical glass, which the company says reduces loss and dispersion for sharper layers. Quoted speed is up to 100 mm per hour, though that figure comes with conditions: Draft resin at 200 microns, 24 – 26 °C, under 50% humidity. Averaged across Raise3D’s resins at 100 microns, it’s 50 – 60 mm per hour. Two details matter for larger parts: Air-Peel technology cuts the per-layer peel force from 50 kilograms to 10 kilograms, the company says, and the Z-axis is rated to a 200-kilogram load.

The printer is sold with DF Wash and DF Cure units tied together by RFID. The tag on each resin container confirms the material before printing and pushes the matching print, wash, and cure settings to all three machines, so an operator who didn’t prepare the job can still post-process it correctly. Ultrasonic sensors feed an auto-refill system for continuous printing. The DF Wash holds 14 liters of IPA or TPM with automatic drainage; the DF Cure takes parts to ø230 × 300 mm using mixed 365/385/405 nm LEDs.

Materials are the strongest argument. The Open Material Platform is free, with no license to unlock, and alongside Raise3D’s own eight resins the qualified list runs to eight Henkel Loctite and five Forward AM Ultracur3D resins, including a flame-retardant grade — so a shop needing ESD-safe, or fire-retardant parts can print them in-house instead of outsourcing. Raise3D aims the machine at functional prototypes, jigs and fixtures, and low-volume end-use parts.

The Form 4L takes much of what makes the Form 4 an easy professional recommendation and scales it up substantially. Its 353 × 196 × 350 mm build volume provides 24.2 liters of capacity – more than four times that of the Form 4 – giving engineering teams room for larger prototypes, tooling, and end-use parts, or substantially larger batches of smaller components.

It uses Formlabs’ Low Force Display masked-SLA technology, with print speeds reaching up to 80 mm/h depending on material and layer height. More importantly, that speed is largely independent of how much of the build platform is filled, making the large build area useful for batch production as well as physically large parts.

The other advantage is the Formlabs ecosystem. Users get PreForm software, remote printer management through Dashboard, automated Form Wash L and Form Cure L post-processing options, and a broad catalog of engineering resins covering tough, rigid, flexible, high-temperature, flame-retardant, and other applications. Open Material Mode also enables third-party 405-nm resins, although it is an optional paid upgrade.

Starting at $7,125 for the basic printer package in the U.S., the Form 4L is not the largest resin printer in this guide, but that’s part of its appeal. It offers a significant increase in capacity without requiring users to move into a much larger, more specialized industrial system. For companies that already like the Formlabs workflow but simply need more room, it is one of the most straightforward steps up in professional resin printing.

Formlabs also offers matching large-format post-processing hardware. The Form Wash L V2 automatically washes a complete Form 4L build platform and costs $4,500, while the Form Cure L V2, also $4,500, uses heat and 405-nm UV light to post-cure large parts and full production batches. Together with the $7,125 Form 4L, that puts the printer, washer, and curing station at $16,125 before resin and other accessories.

The LC Magna is a large-format LCD machine and, at 50 liters of build volume, one of the biggest resin printers you can buy without moving into six figures. Photocentric quotes speeds up to 86 mm per hour at a 350-micron layer, delivered by a patented Blow-Peel mechanism that separates each layer, and a pixel pitch of 137 microns — coarse next to a 50-micron desktop machine, but the trade for a platform that takes a half-meter part or a dense tray of small ones. Two ownership details set it apart from the DLP field: the screen doesn’t suffer UV degradation, which removes the recurring consumable cost that dogs UV-based LCD printers, and the system is fully open, so third-party resins carry no license fee.

Photocentric puts its own resins at $40 to $114 per kilogram and builds an unusually direct cost argument around the machine, publishing a total-cost-of-ownership comparison against Carbon, Stratasys, and Formlabs and claiming its parts consume 11% of the energy per printed kilogram of equivalent FDM parts. The printer is designed and assembled in the UK with 97% UK-sourced components.

Post-processing is handled by two dedicated units, both sized to take an entire Magna platform at full build height so parts can be washed and cured without coming off the plate — which matters for dimensional accuracy on large prints. The Air Wash L is a 90-liter cleaning station that uses combined air and bubble agitation at 40 liters per minute, runs under 40 dB and below 0.5 kW average draw, and is built for 24/7 operation for continuous throughput. It’s designed around Photocentric’s own Resin Cleaner 30. The Cure L2 finishes parts with 405 nm light plus heat up to 60 °C, under thermostat and digital timer control, in a 550 × 350 × 500 mm chamber; the lid cuts power when lifted. Both units carry a 12-month warranty as standard, and Photocentric sells service plans alongside them.

The B9 6 Series MPro stands out less for any single headline specification than for how much freedom it gives engineers over materials. In addition to B9Creations’ own portfolio of engineering, elastomeric, and specialty resins, the 385-nm system is open to third-party materials and can be configured with custom material settings.

B9’s own material range already covers some unusually functional applications, including Rugged Nylon 6 for impact-resistant parts, silicone-like elastomers, ESD-safe resin, ABS-like materials, and high-detail prototyping resins. The MPro is also compatible with selected third-party materials such as Loctite 3D 3843.

Where it becomes particularly interesting for R&D is B9Captivate, the company’s material-development environment. Users can develop and optimize print parameters around custom chemistries, while B9Creations also offers material-development support for applications ranging from engineering resins and ceramics to silicones and other specialized functional materials.

B9Creations also offers its own automated post-processing equipment. The B9Clean handles IPA washing, while the B9 Model Cure and larger B9 Model Cure XL provide programmable UV post-curing, giving users the option of a more complete print-to-finished-part workflow.

With a 192 × 108 × 320 mm build volume, the MPro also has enough capacity for larger functional parts and batch production. For companies that need to work beyond a printer manufacturer’s standard resin catalog, though, its real advantage is the ability to treat the printer and material as a configurable system rather than a fixed ecosystem.

Asiga is best known for dental 3D printing, but its open-material approach also makes its printers interesting for engineering, R&D, and manufacturing applications. The Ultra 50 is the larger of two Ultra models and, for this guide, its biggest attraction is access to Asiga’s unusually broad materials ecosystem.

The Ultra is an open-material DLP platform compatible with more than 650 qualified resins from third-party manufacturers, while also allowing users to create their own material profiles. That opens the door to specialized engineering formulations without tying users to a single resin supplier – an important advantage for companies developing applications around specific mechanical, thermal, elastomeric, casting, or other material properties.

The Ultra 50 has a 189 × 106 × 130 mm build volume and 50-micron pixel size, while the smaller Ultra 32 trades build area for a finer 32-micron pixel size and a 119 × 67 × 130 mm volume. Both use DLP projection with an auto-calibrating 385-nm UV LED light source; 365- and 405-nm versions are available on request. Other professional touches include infrared material heating, touchless hood opening, rapid material changeover, and a magnetic build-platform latch.

Asiga Composer software handles preparation and material parameters, with lifetime software updates included. For post-processing, the Ultra bundle includes Asiga’s compact Flash curing chamber, while the more advanced Asiga Cure adds dose-controlled UV curing, vacuum curing, infrared heating, and customizable profiles for third-party materials. Asiga has a dedicated washing station in the works, but not available yet, instead specifying manual or ultrasonic washing according to the resin manufacturer’s instructions.

The Ultra 50 isn’t a large printer compared with many machines in this guide, but for users who prioritize precision and the freedom to choose from a huge range of third-party materials – or develop their own – its open ecosystem is the reason it stands out.

Launched in 2024, the Stratasys Origin Two is an industrial DLP printer aimed at short-run and on-demand production. Stratasys positions it around high accuracy, repeatability, and surface finish approaching injection molding, making it a strong fit for end-use parts rather than just prototypes.

The printer uses Stratasys’ Programmable PhotoPolymerization (P3) technology and a 4K DLP projector with a 38.5-micron pixel size across a 192 × 108 × 370 mm build volume. A heated chamber supports high-performance and high-viscosity resins, while strong green parts help keep post-processing relatively short.

Origin Two supports a range of Stratasys-validated engineering materials, including tough, elastomeric, high-temperature, and medical-grade resins. An optional OpenAM Material License also allows users to run third-party or custom materials and adjust print parameters.

For post-processing, Stratasys offers the dedicated Origin Cure, which uses multi-wavelength LEDs and programmable curing profiles. There is no matching Origin-branded washer; cleaning requirements depend on the specific resin and validated workflow.

The system runs through GrabCAD Print for preparation, support generation, slicing, and material management. Stratasys does not publish pricing for the Origin Two or Origin Cure, with both sold by quotation.

Introduced in 2025, the 3D Systems Figure 4 135 is designed specifically for high-mix, low-to-mid-volume production of small plastic parts. Its 135 × 76 × 165 mm build area is modest compared with many printers in this guide, but that’s intentional: the emphasis is on throughput, repeatability, and producing precise batches of components such as connectors, housings, sensors, clips, and other end-use parts.

The projector-based system has a 50-micron pixel size and can print a single component or a full platform at similar layer speeds. Production-oriented features include automatic resin feeding from 9-kg cartridges, build and material traceability, fleet management, an automated door that can be operated by foot pedal or software, and provisions for future robotic integration. 3D Systems also offers a broad Figure 4 material portfolio covering tough, rigid, elastomeric, high-temperature, flame-retardant, and other engineering applications.

Post-processing is less integrated than with systems such as Formlabs or Raise3D. 3D Systems does not currently pair the Figure 4 135 with a dedicated automated washing station; its material workflows typically specify manual or ultrasonic cleaning in IPA, with wash times depending on the resin.

For curing, 3D Systems supports the Figure 4 UV Cure Unit 350 as well as the smaller LC-3DPrint Box for compatible parts and materials. Both provide controlled UV post-curing, although the Cure Unit 350 has a taller 346-mm load capacity and is better suited to the broader Figure 4 workflow.

The Figure 4 135 makes the most sense where resin printing is moving beyond prototyping and becoming part of a repeatable manufacturing process. Its small build area won’t suit every application, but for batches of precise production parts, its automation, traceability, and fleet-management features distinguish it from more general-purpose professional resin printers.

The Axtra3D Lumia X1 is a production-focused resin printer built around the company’s Hybrid PhotoSynthesis (HPS) technology, which combines DLP projection with a laser in the same optical system. The idea is to use DLP for speed across larger areas while the laser handles fine features and edges, helping the machine maintain detail and surface quality without sacrificing throughput.

The current Lumia X1 has a 249 × 140 × 495 mm build volume, 45-micron resolution, and layer heights from 25 to 200 microns. Axtra3D positions it for production applications ranging from end-use parts and tooling to molds and medical components, with features including dual Z axes, automated resin handling, and its TruLayer separation system for printing large cross-sections and highly viscous materials reliably.

Materials are another strength. The Lumia X1 is available as an open system compatible with 405-nm resins and has a growing portfolio of validated engineering materials from suppliers including Henkel and other major resin manufacturers. This makes it particularly interesting for manufacturers that want both production repeatability and access to specialized third-party formulations.

Axtra3D now also offers a complete post-processing workflow. Axtra.Wash automates washing and drying of parts, build platforms, and vats and can use up to three cleaning agents, while Axtra.Cure combines multi-wavelength UV curing at 355, 385, and 405 nm with thermal post-processing. Both connect to Axtra.Insight for process monitoring and traceability across printing, washing, and curing.

For small-part production, the Lumia X1’s appeal is its combination of throughput, fine feature reproduction, open materials, and production workflow rather than any one headline specification. It also has enough build height and platform area to handle larger parts or substantial batches when needed.

Within resin 3D printing, more technically known as vat polymerization, you’ll find slightly different printer technologies, including stereolithography (SLA), liquid crystal display (LCD), digital light processing (DLP), and others that create somewhat different results making trade-offs between speed and fine detail. All of these technologies cure resin using UV light, but how the resin polymer is cured is slightly different.

The 3 Major Resin Types in Brief

Stereolithography (SLA) today generally always refers to laser stereolithography, although you might still hear it used as a catch-all term for all types of resin 3D printing. Chuck Hull, who invented the process and coined the term stereolithography, describes it in his 1986 patent as a concentrated “beam” of ultraviolet light focused onto the surface of a vat filled with liquid photopolymer. Today, SLA refers to a machine that uses one or more lasers as the light source.

Digital light processing (DLP) uses a digital light projector as its light “engine”. It flashes light onto a digital micromirror device (DMD) consisting of hundreds of thousands of tiny mirrors. Some mirrors direct the light to the resin in the pattern of a cross-section of the part to be printed while other mirrors deflect the light off to the side. Layers generated using DLP printers consist of so-called voxels, the 3D equivalent of pixels. That’s because the projector screen itself consists of pixels. Flashing an entire layer at a time, as you can guess, is faster than tracing the layer with a laser.

Liquid crystal display (LCD) is the third type of vat polymerization also known as masked stereolithography (MSLA). 3D printer manufacturers use these terms interchangeably. This 3D printing technology is nearly the same as DLP in that it flashes a complete layer at the resin tank, but the source of the light is different. Instead of a projector shining on a digital micromirror, the UV light comes from an LED array shining through an LCD screen. The screen acts as a mask, revealing only the pixels necessary for the current layer. Due to the low cost of LCD units compared to projectors and micromirrors, LCD has become a common technology for the budget desktop resin printer segment, but don’t be put off; some printer makers are taking the technology to the next level for professionals.

We’ve already established that DLP and LCD are generally faster than SLA, but which one yields more finely detailed prints? The fact is that all technologies can produce super-fine details, and you may be surprised by the resolution you can get from very affordable machines.

Patented Resin Technologies

Although some patented resin 3D printing technologies are more marketing than science, some manufacturers have variations on the common technologies (SLA, LCD, and DLP) that actually represent significant advances and set their machines apart from the rest.

3D printer manufacturer Carbon, for example, calls its resin printing technology Digital Light Synthesis (DLS), which is a take on DLP. In DLS, the resin pool is exposed to both UV light and oxygen. Unlike traditional layer-by-layer approaches, DLS uses a continuous process where the object is pulled from the resin bath. The bottom of the resin pool has an oxygen-permeable window. Oxygen inhibits the curing process, and by controlling the oxygen levels through the window, the printer can precisely control the solidification of the resin. DLS requires special resins and the entire process is extremely fast.

Printer maker Stratasys offers another take on DLP in its Origin printer called Programmable Photopolymerization (P³). The outstanding feature of P³ is its ability to dynamically adjust the light patterns during the exposure process to create more sophisticated curing profiles, leading to, the company says, improved accuracy and the ability to optimize material properties.

Formlabs offers what it calles Low Force Stereolithography (LFS), while one new technology from Axtra3D combines resin methods, so the core of a part is printed quickly with DLP while the outer shell is printed with finer detail using SLA. The company calls it Hybrid PhotoSynthesis (HPS) technology.

If looking at a printer’s technical specification sheet makes your head spin, know that you won’t find huge differences within comparable price ranges using the same technology. For example, the finest XY resolution for resin printers (apart from the industrial micro 3D printers) is generally around 25 – 50 microns (μm). (For reference, 50 μm is the width of a human hair.)

Some manufacturers only talk about resolution, while others mention resolution and accuracy. Resolution refers to the possible layer thickness, for example, 50 μm or 100 μm. The accuracy refers to the window of error for consistency print after print. For example, an accuracy of +/- 20 μm means your print resolution could be 20 μm over or under what you programmed.

In many industries, accuracy is critical. For most dental applications, professionals typically look for an accuracy of within 50 μm. For fine jewelry, some professionals require an accuracy of 25 μm, and for some medical applications and electronics, companies require an XY printing resolution of 5 μm with an even smaller accuracy, which you can find in a handful of ultra-high micro-precision printers.

The general rule is that the higher the resolution, the longer your parts will take to print. But this is where professionals and industrial machines differ from consumer resin printers, printing high-resolution parts quickly.

For a deep dive into resin printer resolution, such as what 4K and 8K resolution refers to and terms like pixel-shift really mean, check out our guide to resolution linked below.

Detail Oriented

The Complete Guide to High-Resolution 3D Printers

Parts don’t emerge from resin 3D printers ready to use, in fact, they’re completely useless. Parts may be only partially polymerized (not fully cured) when they leave the printer, creating opportunities for warping in the cleaning and curing steps. This is one of the drawbacks to resin printing; the often-messy and somewhat labor-intensive post-processing.

Although industrial printers and many professional ones have a fully automated print-wash-cure process, others require more equipment, namely a washing unit and a curing unit.

Indeed, the sophistication of your printer and the quality of your resins are inversely proportional to the amount of post-processing labor involved. So if you’re spending too much time and effort post-processing to get the desired quality, consider upgrading your resin, your printer, or both.

Most resin parts need support structures during printing that require removal after printing. Removing supports and the marks they leave on the surface may involve sanding or polishing.

Most resin printer manufacturers make their own accessory machines (if they are not fully incorporated into one unit) and many produce their own post-processing chemicals, but you’re not limited to selecting only from your printer manufacturer’s offerings. Shop around for the accessories that best fit your needs and budget.

In addition to the extra hardware, you also need to budget for software licenses, materials, and other consumables.

Resin manufacturers will argue that it’s the materials that make the print, and that may often be true. There are thousands of materials available for resin printing from a wide range of manufacturers and at prices ranging from $15 a liter to more than $300. In fact, you can resin-print in everything from a highly flexible silicone-like material to a metal-infused polymer.

Your resin 3D printer, however, is either restricted to proprietary resins or it’s an “open material” machine, meaning it can print with a wide range of third-party materials offering great flexibility but also a bit of trial and error to dial in the print settings just right. To cut down on the tinkering, printer makers often work directly with the resin material developers to establish optimal setting. You may hear of certain materials being “certified” for certain printers. This is something to look for, since it’s designed to save you time and money.

Resin Variety

Resins come in a full rainbow of colors, transparencies, properties, and textures. At the dawn of resin 3D printing, most printed parts were stiff and brittle. Those days are long gone. There are flexible resins, durable resins, filled resins, hybrid resins, exotic resins, biocompatible resins, and degradable plant-based resins among many more categories. Yet, because most professional resins are trademarked, proprietary formulas, it can be difficult to understand the differences. For example, most resin makers offer a “tough” resin, but how one tough resin compares to another is often difficult to track down.

Not Weak At All

SLA Resin Strength: How Strong Is 3D Printed Resin?

Note that resins are typically formulated to be responsive to specific wavelengths of UV light, such as 355 nm, 385 nm, or 405 nm. If your 3D printer emits 355 nm light, don’t use a 405 nm resin. Fortunately, most resins today will cure in all three wavelengths, but always follow the manufacturer’s recommendations for resin compatibility and curing conditions to achieve the best results in 3D printing.

Likewise, a resin formulated for a DLP 3D printer may not work in an SLA printer, so read labels carefully.

Manufacturer vs. Third-Party Materials

A resin printer’s claims of accuracy, speed, and quality are based on using specific resins. Although you can use third-party resins in many resin printers, your results may not match what the manufacturer claims its printer can produce. For example, the resin part may not fully cure or may not print as fast with a third-party material.

Despite the risks of uncertified third-party materials, a resin printer with an open-mode or experimental mode for materials is an important feature. Material manufacturers are introducing new resins so quickly that it’s often not possible for printer manufacturers to keep up on certifying or adapting innovative materials for use in their machines. Open-mode enables you to take advantage of the latest developments in materials.

Several printer manufacturers have alliances with major chemical companies to research and develop proprietary materials.

Of course, there are plenty of high-quality resins by third-party manufacturers that will work as good or even better in whichever machine you choose. The only drawback, as we mentioned above, is taking the extra time to experiment and fine-tune your print settings and post-processing to get the print you require.

Many resin manufacturers, including Liqcreate, offer custom material development to fit your company’s specific needs for colors, properties, and the specific printer you’re using. In fact the company has produced nearly two dozen custom resins in the past few years.

By working with engineers at consumer product companies, such as Adidas, Invisalign, and Riddell, resin manufacturers have researched and created application-specific resins and helped 3D printing to rival injection molding and further the mass production of end-use products.

If you have specific requirements for your final part’s stiffness, strength, stretch, durability, heat resistance, or other attributes, check out the materials’ technical data sheet, which should provide details including tensile strength, percent of elongation at break, and water absorption.

Ultimately, where you buy your resins may be tied to your location. Although companies in Europe and North America may have the widest selection of vendors to choose from, companies elsewhere may want to first try sourcing resins locally before paying shipping and import duties for the printer manufacturer brands.
