Design Guidelines: Carbon DLS

Our basic guidelines for Carbon DLS (digital light synthesis) include important design considerations to help improve part manufacturability, enhance cosmetic appearance, and reduce overall production time.

Size

Maximum Dimensions

NORMAL RESOLUTION 7.4 in. x 4.6 in. x 12.8 in.
NORMAL RESOLUTION 189mm x 118mm x 326mm

Accuracy

Layer Thickness

NORMAL RESOLUTION                               0.004 in.
NORMAL RESOLUTION 0.100mm

Minimum Feature Size

STRUCTURAL WALL THICKNESS 0.100 in.
SUPPORTED WALLS (RIBS, BOSSES, ETC.) 0.040 in.
POSITIVE FEATURES 0.020 in.
NEGATIVE FEATURES/HOLES 0.025 in.
STRUCTURAL WALL THICKNESS 2.5mm
SUPPORTED WALLS (RIBS, BOSSES, ETC.) 1.0mm
POSITIVE FEATURES 0.5mm
NEGATIVE FEATURES/HOLES 0.6mm

Expected tolerances are +/- 0.010 in. (0.25mm) for the first inch plus +/-0.0015 in./in. (0.0015mm/mm) for each additional inch. Keep in mind that tolerances are not guaranteed on your first build of parts, however, we will work closely with you to help achieve critical dimensions. Please request critical dimensions when you upload your part, and our applications engineers will quickly review and provide feedback.


Materials

We offer an ABS-like rigid polyurethane (Carbon RPU 70) that works well for general purpose uses and a PP-like polyurethane (Carbon FPU 50) that is ideal for applications requiring flexibility and durability.

Surface Finishes

UNFINISHED Dots, or standing"nibs," remain evident on the bottom of the part from the support structure remnants.
NATURAL (Default)
Supported surfaces are sanded down to eliminate the support nibs.

Special Operations

Additional finishing processes to aid in assembly and meet your exact specifications are available. These include:

  • Taps
  • Threaded inserts
