Additive Manufacturing Technologies: Overview Pros & Cons

Image of Additive Manufacturing Technologies: Overview: Pros & Cons

While 3D printing is a considerably groundbreaking technology, there are advantages and disadvantages that it can offer. If you’re thinking about integrating additive manufacturing technologies into your business, it’s important to recognize the pros and cons.

Additive Manufacturing Technologies: Pros

  • Speed – One of the primary advantages of additive manufacturing technologies is its ability to produce parts at a faster rate than other conventional manufacturing techniques. This is especially beneficial for rapid prototyping, allowing a designer to hold a physical representation of their idea in a matter of hours. This enables businesses and manufacturers to identify potential issues and fix them quickly.
  • Reduced Cost – In most cases, additive manufacturing technologies will also reduce cost and expenses in a number of ways. For starters, the energy costs for machine operations are generally low, especially when you consider the quick production turnaround. 3D printing technology also helps to reduce the cost of materials and labor. But most importantly, it offers risk mitigation when it comes to the manufacturing workflow. By utilizing additive manufacturing technologies for rapid prototyping, businesses are able to observe and repair models before sending them off for final production. This greatly reduces the risk of unnecessary expenditures during the production process.
  • Increased Design Freedom/Complex Geometries – Another major pro that additive manufacturing technologies offer is immense design freedom and the ability to produce complex geometries. Due to the layer-by-layer process used with 3D printing technology, you’re able to achieve angles and shapes that are nearly impossible with other manufacturing techniques.
  • Accessibility – Each year, additive manufacturing technologies become more affordable and capable, thus making it increasingly accessible for a wider range of industrial uses. With this growth also comes increased knowledge and ease of use, meaning that a larger number of people will be able to integrate this technology into their workflow. The industry has blossomed over the past five or so years, leading to innovations and new technologies that will continue to make 3D printing the most exciting new manufacturing technique around.
  • Customization – One of the prized points of additive manufacturing technologies is the ability for mass customization. Since 3D printed parts are generally produced one at a time, this gives designers and businesses the ability to alter, modify, or customize their products as they see fit. Whether it’s the medical industry creating patient-specific surgical guides or a manufacturer producing personalized products, mass customization is one of the main selling points of additive manufacturing.
  • Sustainability – Another benefit to additive manufacturing technologies is sustainability. Compared to other techniques like CNC milling, 3D printing technology uses much less material waste. This also reduces the need to ship prototypes and products long distances. Now, digital files can be sent and produced anywhere with a 3D printer.

Additive Manufacturing Technologies: Cons

  • Material Limitations – One of reasons that additive manufacturing technologies are not always well suited for use-end production is because of material limitations. While this is an issue that is slowly being solved, the current line of professional 3D printing materials are lacking in mechanical properties. Since these objects are being built in layers, you will have weaker and less dense parts compared to CNC milling or injection molding. However, as the industry continues to advance, so do the material capabilities.
  • Size Limitations – Another disadvantage of additive manufacturing technologies is also size limitations. The size capabilities are limited to the build volume of the printer, meaning that you can not print beyond the preset limitations. Not only does this prevent the production of extremely large objects, but also an abundance of small prints at once.
  • Questionable Accuracy – If you’re looking to produce something that needs pinpoint accuracy, you will have to use additive manufacturing technologies with caution. Many materials will print within a erroneous margin of +/- 0.1 mm in accuracy. The 3D printing industry continues to advance in this regard, but be sure to check the accuracy of a machine before you invest in an industrial 3D printer or service.
  • Manufacturing Limitations – Although 3D printing has undeniable value in rapid prototyping applications, there are glaring limitations when it comes to manufacturing beyond that. While additive manufacturing technologies can help save money for prototyping and short-run productions, those advantages turn into disadvantages in terms of mass production. With techniques like injection molding and thermoforming offering faster and cheaper solutions for final products, 3D printing has not yet reached this level of potential.

Additive Manufacturing Technologies: In Depth

There are a number of different 3D printing processes that offer a variety of benefits and capabilities. Here are the most popular additive manufacturing techniques.

1

Additive Manufacturing Technologies: In Depth Fused Deposition Modeling

Image of Additive Manufacturing Technologies: In Depth: Fused Deposition Modeling

Fused Deposition Modeling (FDM) is perhaps the most popular and widely used form of additive manufacturing. The process is quite simple. A material, usually a polymer, is dispensed through a heated nozzle. The FDM printer builds the selected 3D model up layer-by-layer.

The nozzle component moves in horizontal and vertical directions using a numerically controlled mechanism called G-code. The extrusion head uses stepper motors or servo motors to automate movement.

Although the FDM process is typically restricted to printing with polymers, there are a wide range of compatible materials. These include ABS, PLA,  Polycarbonate (PC), Polyamide (PA), Polystyrene, as well as lignin, rubber, and many other material options.

Known as one of the most prominent forms of rapid prototyping, FDM printing is widely used for prototyping and rapid manufacturing. This technique is best utilized for iterative testing of functional prototyping and short-run manufacturing. In many cases, it’s a much more cost efficient solution compared to methods like injection molding.

FDM printing was originally developed in the late 1980s by S. Scott Crump. Shortly after, it was commercialized and patented by Stratasys, which remains one of the world’s leading additive manufacturing companies.

Additive Manufacturing Technologies: In Depth Stereolithography/Digital Light Processing

Image of Additive Manufacturing Technologies: In Depth: Stereolithography/Digital Light Processing

Stereolithography (SLA) and Digital Light Processing (DLP) are also popular additive manufacturing technologies. Although the printing output from these two technologies are similar, the inner workings of these processes are a bit different.

SLA technology uses two motors (aka galvanometers) to quickly aim a laser beam throughout a vat of photopolymer resin. The design is broken into a series of points, while the laser solidifies these points to create a 3D model. An elevator apparatus is used to lift the model layer-by-layer, which is covered with a fresh coating of resin. After the process is complete, the 3D printed model is immersed within a chemical bath to remove any excess resin. Finally, the design is cured in an ultraviolet oven, creating an incredibly smooth finish with high resolution.

The term “stereolithography” was coined in 1986 by Chuck Hull, the founder of 3D Systems, but the technology has been around since the 1970s.

Although similar, the DLP process uses a slightly different approach to photopolymer 3D printing. A digital projector screen flashes an image of the design on each layer. The model is projected across the entire platform at once. This image is composed of square pixels, meaning that each layer of the print is constructed of extremely small rectangular bricks called voxels.

With a slightly different process, there are differences in performance and benefits between SLA and DLP additive manufacturing. Since DLP technology projects the entire model at once, it’s generally capable of providing faster print times, especially when printing large objects.

However, SLA 3D printing is able to print high-resolution parts regardless of the build volume, making it more capable of manufacturing many detailed objects across the entire printing chamber.

Basically, SLA printers are advantageous when it comes to printing many small parts with intricate detail and complex large prints. DLP printers are ideal for producing one-off intricate parts and printing large parts without the need for high resolution.

Additive Manufacturing Technologies: In Depth Selective Laser Sintering

Image of Additive Manufacturing Technologies: In Depth: Selective Laser Sintering

Selective laser sintering is the additive manufacturing process you should be looking towards if your goal is to produce metal objects. This technology uses a high powered laser to fuse small particles of material in a 3D model. This powdered material ranges from metals, plastics, ceramics, and glass.

Typically using a pulsed laster, SLS printers merges the material one layer at a time. After the first layer of the model is fused, the powder bed is lowered and a new coating of material is applied. This process repeats until the print is complete.

Since the object is always surrounded by powdered material, SLS has the ability to print objects without support structures. Additionally, a technique known as “nesting” makes the manufacturing of multiple parts less difficult and costly. Nesting is when a large number parts can be positioned to fill the entire build volume of the machine.

However, it’s important to note that SLS printing is impossible to manufacture a fully enclosed object that is hollow. The reason for this is that, without an exit point in the model, the powder material is trapped inside. Still, there are ways to get around this, such putting a hollow point in your model or printing a fully enclosed object in separate parts.

SLS was developed and patented in the 1980s by Dr. Carl Deckard and Dr. Joe Beaman at the University of Texas at Austin.

Additive Manufacturing Technologies: In Depth Selective Laser Melting/Electron Beam Melting

Image of Additive Manufacturing Technologies: In Depth: Selective Laser Melting/Electron Beam Melting

Considered a subcategory of the SLS process, selective laser melting also used a high-powered density laser to melt and bind grains of metal powders together. However, the additive manufacturing process is capable of melting metal material into a completely solid part.

By fully melting and liquefying the metal instead of just fusing the powder together, SLM printing can create homogeneous parts. This leads to less porosity and more control over the crystallization of the material, ultimately creating stronger parts.

The printing process transpires within a chamber that contains an atmosphere of inert gas. Each layer of the part is fused by selectively melting the powder with a high-powered ytterbium fiber laser. The laser beam is directed in both the X and Y directions with two high frequency scanning mirrors.

The energy of this laser is intense enough to weld the material particles together into a solid metal object. SLM is compatible with atomized materials that include copper, aluminum, stainless steel, toll steel, cobalt chrome, titanium, and tungsten.

Electron beam melting is a similar additive manufacturing method that uses an electron beam as the heat source. However, EBM usually offers a more efficient build rate because of its high-energy density and scanning method.

There are also metal wire based systems where an electron beam is used to melt welding wire to build a part. This process is more akin to FDM printing, but with metal wiring instead of plastic filament.

Additive Manufacturing Technologies: In Depth Binder Jetting/Inkjet

Image of Additive Manufacturing Technologies: In Depth: Binder Jetting/Inkjet

Binder jetting (aka inkjet) is an additive manufacturing technique that uses a liquid binding agent to connect powder particles together. The process uses a printhead the selectively drops this binder into the powder. This build area lowers down layer-by-layer, enabling the production of a full-on object with a mixture of powder and binder.

This type of technology is capable of printing a variety of metals, sands, and ceramics. Depending on the material, the print may or may not require post-processing. For example, metal objects manufactured with binder jetting can achieve greater density by using a hot isostatic pressing technique after printing.

The Binder jetting process is similar to 2D printing in that the binder acts like an ink that moves methodically across the layers of powder. Unlike other 3D printing techniques, binder jetting technology does not employ heat during the build process.

The advantages of binder jetting includes the ability to print large parts at a faster rate, while also being more cost effective than other additive manufacturing technologies.
