SLA / DLP
Durable, Fast, Production Components
DLP (Direct Light Printing) is a process that utilizes photo-curable liquid polymers and supporting structures. This process works with the FIGURE 4 MODULAR. It creates parts with high tolerances and great surface finishes. The ability to produce crisp, clean, sharp edges, fast, with production quality, is what separates DLP from similar technologies.
SLA (Stereolithography) is a 3D printing technology that uses a laser to cure liquid resin layer by layer. This process can utilize a wide variety of materials ranging from abs like plastic, to rubbers, clear plastics, high temp plastics, and much more.
DLP and SLA is ideal for high end prototyping jobs that need internal structure visualization or fit validation in assemblies as well as Low-Medium Production Quantities for a variety of applications.
Stereolithography (SLA) and Direct Light Printing (DLP) Process
Step 1
Plate is lowered into the bed of resin.
Step 2
Energy (UV Light) is applied to solidify a cross-section of part
Step 3
Platform is raised and next layer of resin is cured. Process is repeated.
Step 4
Supports are removed. Finish part is revealed.

Max Size Capabilities
Living hinges & complex geometries are made possible with this technology. Surface finish is similar to injection molding, which creates a production like appearance. Geometries can affect warping, so if you have questions on how to design using SLA or DLP reach out to us right away. This process is NOT suitable for stacking parts.
| Dimension | Capacity |
|---|---|
| X (length) | 30" (124.8 mm) |
| Y (width) | 30" (70.2 mm) |
| Z (depth) | 23" (346 mm) |
| Layer Thickness | The normal resolution layer thickness is 0.004 in, and the minimum feature size is 0.012 in. The high-resolution layer thickness is 0.002 in, and the minimum feature size is 0.006 in (feature size depends on geometry). |
Materials
Materials are produced by 3D Systems, one of the largest 3D printing companies. The materials are liquid polymers that are cured utilizing a UV light.

Tolerances
Because of the small layer thicknesses, tolerances are unparalleled compared to other 3D printing technologies. This can be taken advantage of during the prototype phase into production applications.
- ± 0.005 in for the first inch and ± 0.0015 in/in for each additional inch
