SLA ® (Stereolithography)

Stereolithography is a process which produces a physical, three dimensional object, conceptual model, or master pattern utilizing 3D CAD Data. A rapid prototyping machine uses a computer controlled laser to cure a photo-sensitive resin, layer by layer, to create the 3D part. SLA ® parts greatly assist in the visualization of a product, as well as communication between project team members.

Max Part Size 20" x 20" x 24"
Tolerance +/- .005 +.001/in
Min Feature Size 0.015
Resolution .001" to .006" Layers
Avg Lead Time 1-2 days
Paintable Yes

LS (Laser Sintering)

Laser Sintering is another "additive" process that sinters (fuses) a variety of materials, including nylon, glass-filled nylon, and steel, to "grow" 3D objects layer-by-layer from 3D CAD data. It can also be used to fabricate metal and ceramic objects and tools. Because this is an additive process, highly complex geometries can be built without issue, and because the powder used in the process help to support the parts as they are grown, no additional support structures have to be added and removed. The key advantage of LS is its ability to rapidly produce durable, functional objects for a wide variety of applications.

Max Part Size 11" x 13" x 15"
Tolerance +/- .010/in
Min Feature Size 0.025
Resolution .004" to .006" Layers
Avg Lead Time 2-4 days
Paintable Yes

DMLS (Direct Metal Laser Sintering)

The DMLS (Direct Metal Laser Sintering) process is additive prototyping and manufacturing for metals. In this process, powdered metal is sintered at 20-micron layers, which are traced in the X and Y-axes before the build tray lowers 20 microns. The recoater then sweeps over a new layer of powder 20 microns thin, allowing a new layer to be sintered on the already built layer.  Though layers are sintered, it actually requires support structures, a requirement also found in the SLA ® process. Support material is the actual sintered metal. Parts require a variety of post processes, including heat treating, support removal, shot peening and more.

Max Part Size 9" x 9" x 8"
Tolerance +/- .005 +.001/in
Min Feature Size 0.025
Resolution 20 micron layers
Avg Lead Time 5-7 days
Paintable No

RTV or Urethane Casting

Room Temperature Vulcanizing (RTV) Silicone is used to create molds that can cast up to 100 parts from one mold (depending on part geometry) in a variety of materials that mimic production quality parts. The process begins with the creation of a high-resolution master pattern. This master pattern is then used to create a RTV silicone mold which will then will be used to cast the duplicates. Since the silicone mold is flexible, undercuts and difficult geometries can be produced.

Max Part Size No Limit
Tolerance Controlled by Master
Min Feature Size 0.015
Resolution Controlled by Master
Avg Lead Time 7-9 days First Article
Paintable Yes

3DP (3D Printing)

3D Printing, especially Polyjet Technologies, is excellent at reproducing very fine surface detail and texturing. The technology is also capable of using two different materials during the same build. Some common applications are producing over molds on parts and medical models used in planning surgery.

Max Part Size 19" x 15" x 8"
Tolerance +/- .004/in to +.010/in
Min Feature Size 0.025
Resolution 16 Micron Layer
Avg Lead Time 2-4 days
Paintable Yes

Prototype Aluminum Casting

Our prototypes are made either by the plaster or air-set sand process. The type of casting dictates the method that we use, unless specified by our customer.

The plaster process is used when fine detail and finish are essential.

Rubber patterns can be used when making plaster molds. When using rubber patterns, minimal or no draft is needed, facilitating a cast to print part.

Max Part Size 19" x 15" x 8"
Tolerance +/- .004/in to +.010/in
Min Feature Size 0.060 Walls
Materials Available Alum, Zinc, Bronze
Avg Lead Time 2-3 Weeks

CNC (Computer Numerical Control)

Computer Numerical Control (CNC) equipment utilizes a process that is known as subtractive manufacturing. This process can produce parts out of a wide range of materials. It can also hold tolerances that are typically less than +/-.005". For more information on these capabilities, click to download the PDF below.

Max Part Size 18" x 20" x 18"
Accuracy /Repeatability +/- .0002 / +-.0002
Min Feature Size 0.025 Wall Thickness
Avg Lead Time 7-10 days

Metal Plating

Applying Metal Plating to a SLA ® part will improved the model's mechanical properties. The metal plating will provide an increased resistance to chemicals, improve heat deflection, help waterproof the model, and improve impact strength (up to 3x). Plating needs to be analyzed on a per project basis. For additional information, please contact your project manager.

3D Laser Scanning

Laser Scanning is a non-contact method of retrieving 3D data from the host object. The process consists of shining a structured laser line over the surface of an object in order to collect 3-dimensional data. The surface data is captured by a camera sensor mounted in the laser scanner, which records the 3D points in reference to one another. For additional information, please contact your project manager.
