What are the Differences Between LCD, DLP and SLA 3D Printing?

Although SLA and DLP technology are extremely similar in principle, there are slight differences that separate the two.

SLA 3D printing utilizes two motors known as galvanometers. These motors, placed on the X and Y axis, work together to aim a laser beam across the print area, solidifying resin into a 3D model. The layers of the model are broken down into a series of points and lines, which the galvos use to direct the laser beam.

On the other hand, DLP technology uses a digital projector screen to flash a single image of each layer across the entire platform at once. Each layer of the 3D model is displayed as square pixels, meaning that the print is comprised of voxels.

As for LCD 3D printing, the process is nearly identical to DLP in that it utilizes projected light to solidify resin layer-by-layer until a 3D model is built. The main difference is that LCD 3D printers project light through an LCD panel, while DLP 3D printers utilize an array micro-mirrors to project light.

The Sparkmaker introduced itself to the 3D printing community via a successful Kickstart project, and thankfully the company behind this compact SLA machine delivered to backers. This print has managed to beat out other budget resin 3D printers like the Anycubic Photon as far as price goes, and can even be found online for as low as $250.

Considering that the cheapest SLA 3D printer in its respective market, the Sparkmaker does lack certain features that other resin-based machines offer. For instance, it has a small build volume of 98 x 55 x 125mm and no touchscreen, opting instead to use a simple button that starts and stops the machine.

The Micromake L2 is one of the most unique DLP 3D printers on our list. This is because it offers a built-in UV curing light module to cure models directly within the machine. The hood has a sealing ring that effectively keeps the nauseating and hazardous odor of resin from escaping from the printer.

Outside of the special built-in UV curing chamber, the Micromake L2 provides a build volume of 108 x 65 x 200mm, XY resolution of 57 microns and an exposure time of 2 to 15 seconds. This printer also has Wifi connectivity and a 4.3-inch high-definition touchscreen. Priced right around the $500 mark, this DLP 3D printer offers some great features for a surprisingly low price.

Priced at just under $500, it’s no surprise that the Anycubic Photon DLP 3D printer has become one of the hottest tickets to getting into resin-based 3D printing. This affordable DLP 3D printer offers an impressive 2k resolution, and also comes pre-assembled.

However, the 115 x 65 x 155mm build volume is a bit small for some people, so if size is of grave importance, you may want to look elsewhere. Otherwise, the AnyCubic Photon DLP 3D printer is an appealing option for makers on a budget who want to venture beyond the world of FDM 3D printing.

DLP 3D Printer Review: 2018 Anycubic Photon Review – Best Budget Resin 3D Printer

Although the AnyCubic Photon is marketed as a DLP 3D printer, there has been some debate over whether that is an accurate description or not. The machine has a UV light source at the bottom, but it shines through the LCD screen, which either blocks or allows the light to shine through. Either way, most users seem extremely satisfied with this resin-based 3D printer, and that’s reason enough to place it atop our list of DLP 3D printers.

Widely recognized for bringing incredibly affordable desktop FDM 3D printers onto the market, Monoprice is also getting its feet sticky with cheap resin 3D printing as well. The manufacturer has already refined its first “SLA” 3D printer, resulting in the Monoprice MP Mini Deluxe SLA. The name is a bit misleading, considering that this printer uses an LCD screen. However, when it comes to price and potential, this resin 3D printer could soon be on the same level as the AnyCubic Photon .

The MP Mini Deluxe SLA is capable of printing at a resolution of up to 20 microns. It can also print with negative gaps as small as 30 microns. You also get a relatively speedy printer that can print up to 30mm/hour vertically. Monoprice claims that this desktop resin machine is compatible with a wide variety of UV resins, making it ideal for beginners looking to prototype for applications in the medical and dental field, as well as jewelry.
