3D Printing Services & Technologies

Since its inception during the late 1980s, additive technologies have transformed the way products are prototyped. Software and hardware have come a long way in the past decades. Prototyping by way of additive technologies continues to be one of the fastest and most cost-effective methods. While prototyping and additive technologies are ever-changing, so are the means of production. Today, the term Additive Manufacturing (AM) is more commonly utilized further downstream in the production phases of product development.

What is 3D Printing Additive Manufacturing?

Additive manufacturing constructs 3D models by layering materials. The object is made by following specifications laid out by a Computer-Aided Design (CAD) or a digital 3D model. AM may use a number of materials from polymers, metals, glass, ceramics, foams, gels and more. Additive manufacturing applications include industrial tooling, customized products, production parts, a visualization tool in design and more.

There are numerous processes used by additive manufacturing technologies. These include / /

  • Vat Polymerization / / The part is made layer-by-layer in a liquid resin photopolymer vat. Ultraviolet (UV) light cures the resin while a platform moves downward after each layer has hardened.
  • Sheet Lamination / / Thin sheets are bonded together in layers to form a single part.
  • Powder Bed Fusion (PBF)  / / Ultra-fine layers of powder are laid onto a build platform and then bonded by lasers, electron beams, or thermal print heads. PBF is used by some AM technologies, including Direct Metal Laser Sintering (DMLS), Selective Laser Sintering (SLS), selective heat sintering, Direct Metal Laser Melting (DMLM) and electron beam melting.
  • Material Jetting / /  A print head moves along x, y and z axes to distribute photosensitive material layer-by-layer. The material is then cured by a UV light.
  • Binder Jetting / / A binder is deposited onto a powder bed, bonding layers one at a time—used for metal, sand and ceramic in powder/granule form.
  • Directed Energy Deposition / / A laser mounted to a 4 or 5 axes arm melts filament feedstock or powder.
  • Material Extrusion / / A heated nozzle distributes a spool of the thermoplastic polymer in a continuous stream, depositing the material layer-by-layer to build a part.

Additive Manufacturing Benefits

If you are searching for an economical solution for your project, AM can be the right choice. Rather than assembling your product from multiple components or using multiple machines and processes, creating a product may be as simple as a good design. The right material and a single device can make measurable impact on your product development process. Bring your product to market at a rapid pace with additive manufacturing. Functional integration and adaptations can be directly designed into the product, reducing the number of development cycles. Review these additive manufacturing benefits / /

3D Printing vs. Injection Molding

3D printing manufacturing and injection molding are significantly different manufacturing processes. 3D printing is an additive manufacturing method in which parts are built layer-by-layer until a product is created. 3D printing is a good fit for projects that require a lower volume of products, complex and intricate designs and any project that may require quick changes early in the product development cycle. Injection molding utilizes a mold into which molten material is injected. Once the material has cooled, the part is removed from the mold. Injection molding is perfect for large volumes, components that are not complex or delicate and parts that require enhanced strength. Learn more about 3D Printing vs. Injection Molding

Rapid Prototypes

Rapid prototyping is the process of creating a physical part from a CAD design. The resulting rapid prototype can test a product design’s functionality or efficiency before the part is reproduced in larger volumes. Additive manufacturing methods allow companies to create a rapid prototype quickly. The benefits of rapid prototyping include the ability to gather valuable feedback from clients and investors, receive funding, make quick changes early in the product development cycle. Rapid prototypes can also reduce waste, save time and effectively communicate concepts. Rapid prototypes can also be used to test fit, size and overall appearance.

3D Printing Materials

Polymers, metals and ceramics are the primary types of materials used for additive manufacturing/3D printing. Additional materials may include different types of paper, food, or polymer adhesive sheets. Common polymers for 3D printing include Acrylonitrile Butadiene Styrene (ABS) and Polycarbonate (PC). Polymers can be combined to create a range of other materials that have different structural and aesthetic properties. 3D printed metals include steel, titanium, aluminum and cobalt chrome alloy. 3D printed ceramic materials are porcelain, silicone-carbide and silica/glass. The proper material must be matched with the appropriate additive manufacturing technology. No matter which material or additive technology you choose, you can expect a high-quality part from Fathom.

PolyJet (PJ) 3D Printing

What is Poly Jet? PolyJet (PJ) technology is a 3D printing process that can achieve smooth surfaces, thin walls and complex geometries with accuracy as high as 0.1mm. It is the only technology that supports a wide range of materials with properties that range from rubber to rigid, and transparent to opaque. PolyJet is commonly used for prototyping and is best for projects where accuracy, finish and detail are required.

How does a PolyJet printer work? The PolyJet printer operates like an inkjet printer, but instead of using drops of ink, the printer extrudes photopolymers that solidify or cure under UV light. Layers are built on a build tray until the part is made. When an intricate design is desired, the 3D printer uses a gel-like support material that enables complex geometries. The gel is easily removed by soaking or water jetting.

Is PolyJet a type of SLA technology? While both PolyJet and SLA use a resin cured by UV light, some notable differences are observed. First, there is no need for a resin bath like in SLA. Second, PJ printers utilize a gel material for the support that can be washed away, whereas SLA printers use break-away support materials. Lastly, PJ printers produce parts with no liquid resin residue, which means there is no need to wash the post-production piece.

PolyJet Advantages / /

  • Produce Intricate Designs, Complex Details & Precise Features
  • Utilize a Variety of Colors & Materials into One Model for Increased Efficiency

Stereolithography (SLA) 3D Printing

What is the Stereolithography? Stereolithography technology is ideal for high-resolution finishes regarding medium- to large-sized parts. While there are fewer materials to choose from versus PolyJet, it is an extremely cost-effective solution for creating durable, aesthetically pleasing parts. SLA offers scalability due to the sizes of the machines, which allows the production of parts of considerable size. SLA is designed for parts that only require one material. Every component of the part must be made from a single material.

How does an SLA printer work? SLA uses a bath of resin and UV laser beams to create parts. The laser traces a shape dictated by the original file across the surface of the resin bath. The resin touched by the laser hardens, then the build platform descends in the resin bath and the process is repeated until the entire part is complete. A chemical bath may be used to clean the piece. Once the part has been cleaned, it is ready to be used.

What is the difference between Stereolithography and 3D printing? Stereolithography is a methodology of 3D printing. It is one of the earliest used methods of 3D printing technology. Chuck Hull patented SLA in 1984 as a process to create 3D objects by using thin layers and then curing those layers using UV light.

Stereolithography Advantages / /

  • Great for High-Resolution Finishes
  • Minimal Variances
  • Accurate & Durable Parts
  • Rapid Production
  • Strong Enough to be Machined

Fused Deposition Modeling (FDM)

What is FDM? Fused Deposition Modeling (FDM) technology is an ideal fabrication method for all kinds of applications because of its wide range of engineering-grade thermoplastics—from concept models, functional prototypes and end-use parts such as final goods and manufacturing aides (e.g., jigs and fixtures).

How does an FDM 3D printer work? FDM is a filament-based additive technology distributed by a moving print head that extrudes a heated thermoplastic material in a pattern layer by layer onto a build platform. This technology includes the use of support material to create supportive structures removed by force or solution. During printing, the support and molding material takes the form of filaments or threads which are fed through a nozzle. The filament is then extruded onto the build platform. Both the nozzle and base are controlled by a computer following a CAD design. Production time depends on the size of the object being produced.

What materials are used in FDM? The most common material used for FDM is Acrylonitrile Butadiene Styrene (ABS). Other materials used in FDM include Thermoplastic Polyurethane Elastomer (TPU), Antero™ 800NA (polyetherketoneketone), ULTEM™ 1010 resin (polyetherimide), ULTEM 9085 resin (polyetherimide) and other thermoplastics.

Fused Deposition Modeling Advantages / /

Multi Jet Fusion (MJF) 3D Printing

What is Multi Jet Fusion (MJF)? Multi Jet Fusion technology is a relatively new technology. Like other 3D printing technologies, MJF builds parts layer-by-layer. A thin layer of powder is placed repeatedly onto a print bed. The inkjet array inside the print carriage makes a sweeping motion over the print bed, releasing two agents downward; a fusing agent and a detailing agent. The fusing agent fuses the powder together. The detailing agent is used to reduce fusing at the part boundary in order to achieve greater detail.

Multi Jet Fusion is perfect for projects that require a higher density, smooth surface and low porosity. Lead times are much shorter due to minimum to no post-production finishing needs.

What is Multi Jet Fusion 3D printing? This technology is quickly becoming a popular choice for 3D printing prototypes and production parts. Ideal uses for MJF are enclosures, electronics housings, complex ducts, lattice structures and functional assemblies. The technology is capable of 3D printing parts with high detail, as well as suitable for applications that require durability (e.g., snap fits). It is common for designers and engineers to choose this material for short production runs because the MJF process allows for nesting in the z-direction. Offering this technology further expands Fathoms already comprehensive 3D printing and additive manufacturing services.

The material currently available for MJF is Nylon 12 (PA 12), a highly durable thermoplastic that is ideal for functional prototyping and low-volume production runs. Nylon 12 allows for smooth surfaces with fine details and strength. It has excellent resistance to oils, grease, aliphatic hydrocarbons and alkalis. The resulting part is a non-uniform light gray that can be dyed a darker color.

Multi Jet Fusion Advantages / /

  • High Detail
  • Complex Parts
  • Fast Turnaround Times
  • Smooth Surfaces
  • Minimal Need for Post-Production Finishing

Selective Laser Sintering (SLS) 3D Printing

What is Selective Laser Sintering (SLS)? SLS technology is commonly used to create models, prototypes and end-use parts in durable, engineering-grade thermoplastics. Especially great for larger part quantities. Consider SLS for applications that involve high-complexity and organic geometries, as well as parts requiring durability.

How does Selective Laser Sintering work? SLS uses a blade to spread a thin layer of powder over the build volume. A laser sinters the cross-section of the part, fusing the powder together. The z stage then drops one layer and the process begins again until the build is finished. Parts are then excavated from the build powder-cake and bead blasted. The unused powder in the build envelope acts as the support structures, so no support removal is necessary.

What is Selective Laser Sintering used for? Selective Laser Sintering has many advantages for designers and engineers. Common uses of SLS include functional prototypes, concept models, consumer products, architectural models, electronics housings, medical devices, sculptures, jigs, fixtures and more.

Selective Laser Sintering Advantages / /

  • Does Not Require Support Structures
  • Great for Intricate & Complex Geometries
  • Fast Turnaround
  • Strong Layer Adhesion
  • Can Be Dyed

Selective Laser Sintering Applications / /

  • Functional Prototypes

DMLS 3D Printing 

Streamline your manufacturing with precision metal prototypes and low-volume metal production parts that would be otherwise impractical or cost-prohibitive to machine. We create metal parts using a fiber laser fired onto a metal plate, repeatedly adding layers of powdered metal and fusing them to previous layers. Although the resulting part is accurate with excellent surface quality and mechanical properties, additional post-processing is also available.

Metal 3D printing, also known as Direct Metal Laser Sintering (DMLS) and Direct Metal Laser Melting (DMLM) is an additive layer technology. A metal 3D printer utilizes a laser beam to melt 20-60 micron layers of metal powder on top of each other. Powdered metal is spread across the entire build platform and selectively melted to previous layers. This additive process allows metal parts to be grown out of a bed of powdered metal. The process is like other polymer-based 3D printers that use powder bed fusion.

DMLS Advantages

  • Precision
  • High-Quality
  • Low-Volume
  • Strength

DMLS Applications

  • Functional Prototypes
  • Spare Parts
  • Biomedical Implants
  • Tooling
