Production-Grade Parts Without Tooling

Carbon® uses digital light projection, oxygen-permeable optics, and programmable liquid resins to produce products with end-use durability, resolution, and surface finish. This technology, along with Carbon’s custom liquid resins, unlocks new business opportunities and product designs previously impossible, including mass customization and on-demand inventory. The Carbon platform enables companies to bring products to market that were never thought possible.

Available Finishes for Carbon DLS™ Parts
Standard

Parts built with Carbon DLS technology will typically have a matte to semi-gloss surface finish depending on feature direction. Extended protrusions will show vertical lines in the part that are parallel to the direction of growth. Supports are removed and mitigated as required.

Custom Color (UMA 90)

UMA 90 materials come in different colors available for custom mixing. Although the standard is black or white, other solid colors can be available for part productions.

Carbon DLS™ General Tolerances

DescriptionTolerance Notes
Description

General Tolerances

Tolerance Notes

+/- 0.005” for the first inch is typical, plus +/- 0.002” for every inch thereafter.

Description

Build Size

Tolerance Notes

The typical build area is 7.4” x 4.6” x 12.8”. Parts with dimensions exceeding 4” x 4” x 6” will require manual review.

Description

Ideal Part Size

Tolerance Notes

Part's below 2" x 1" x 3" or smaller tend to have the best production economy of scale.

Description

Minimum Wall Thickness

Tolerance Notes

0.030" or larger is suggested for any walls, text, or lattice features.

This table depicts the general tolerances for Digital Light Synthesis™. Stresses during the build, support strategy, and other geometry considerations may cause deviation in tolerances and flatness. Improved tolerances may be possible with a manual quote review, after successful completion of a prototype build, and must be approved on a case-by-case basis. General tolerances apply before secondary finishing or post-processing unless otherwise specified. Please check out Xometry's Manufacturing Standards for more information on tolerances per process.

Overview: What is Carbon DLS™ Technology?

Carbon DLS™ Technology Basics

Carbon uses digital light projection, oxygen-permeable optics, and programmable liquid resins to produce products with end-use durability, resolution, and surface finish. This 3D printing technology is called Digital Light Synthesis™, or DLS for short. Another legacy term for the process is Continuous Liquid Interface Production (CLIP). Along with Carbon’s custom liquid resins, DLS unlocks new business opportunities and product designs previously impossible, including mass customization and on-demand inventory of end-use products.


Carbon bridges, and sometimes substitutes, for processes like Urethane Casting and Injection Molding service production, because the materials are urethane-based or epoxy-based, giving excellent mechanical properties. There are even elastomer and silicone resins that outperform most additive manufactured rubber-like materials.

    What Differentiates Carbon

    What differentiates Xometry's Carbon DLS 3D printing service from similar processes like Stereolithography (SLA) or PolyJet 3D prints is that the resin has a secondary thermal step which activates dormant epoxies or urethanes, making parts much stronger than UV-curing alone. Additionally, the digital light synthesis process is continuous, without stopping layer-by-layer as with most additive manufacturing. This gives the parts isotropic properties, meaning that strength is even regardless of orientation. This is a significant advantage over processes like Fused Deposition Modeling (FDM), where Z-direction features can be much weaker than similar features built in the XY-direction.
