Unless we have agreed to other tolerances in your Quote, we will work to achieve and hold the tolerances noted below, which will vary per the primary manufacturing method you select.

METAL ADDITIVE MANUFACTURING

Danae currently offers Direct Metal Laser Sintering (DMLS) to 3D print metals using additive manufacturing techniques.

DMLS

  • Tolerances of +/- 0.005″ plus 0.002″ per inch is typical for DMLS. However, Danae does not guarantee tolerances on the first attempt of a new design. Tolerance expectations can vary across different materials (e.g. stainless versus aluminum).
  • Internal stresses during build, support strategy and other geometry considerations may cause deviation in tolerances and flatness.
  • Items and geometries which require strict flatness are not a good fit for this process.
  • Expected surface roughness is 150-400 uin RA, depending on build orientation and material used for the build.

NON-METAL ADDITIVE MANUFACTURING

Danae currently offers SLA (Stereolithography), SLS (Selective Laser Sintering), HP MJF (HP Multi Jet Fusion), FDM (Fused Deposition Modeling) and PolyJet across a range of machine and material combinations.

SLA

Tolerances for standard resolution:

  • X/Y planes: +/-005” for the first inch is typical, plus +/- 0.002” for every inch thereafter
  • Z plane: +/- 0.010” for the first inch is typical, plus +/- 0.002” for every inch thereafter
  • Minimum linear feature size: under 0.030” are at risk and under 0.020” will not build
  • Minimum radial feature size: 0.035″

Tolerances for high resolution:

  • X/Y planes: +/- 0.005” for the first inch is typical, plus +/- 0.002” for every inch thereafter
  • Z plane: +/- 0.010” for the first inch is typical, plus +/- 0.002” for every inch thereafter
  • Minimum linear feature size: under 0.020” are at risk and under 0.010” will not build
  • Minimum radial feature size: 0.030″

SLS

  • +/- 0.005″ for the first inch is typical, or +/- 0.002″ per inch, whichever is greater. Build area up to 13 x 13 x 20″ (13″ max dimension preferred)
  • Parts with thicker geometries, flat or broad parts, and parts with uneven wall thicknesses will be prone to significant deviations or warp due to variable thermal shrinkage and stress.
  • Theoretical maximum build volume of 13” x 13” x 20″ (13″ max dimension preferred).

HP MJF

  • +/- 0.012″ or +/- 0.003″ per inch, whichever is greater, is typical.
  • Parts with thicker geometries, flat or broad parts, and parts with uneven wall thicknesses will be prone to significant deviations or warp due to variable thermal shrinkage and stress.
  • Theoretical maximum build volume of 380 x 284 x 380 mm* or 15 x 11 x 15 in. 14 x 11 x 13 in. is the recommended useable area.
  • Natural grey color may be inconsistent depending on feature size and build orientation. Dyed black is recommended for production parts.

FDM

  • +/- 0.004″ for the first inch is typical, or +/- 0.002″ per inch in the XY-direction, whichever is greater.
  • +/- 0.010″ for the first inch is typical, or +/- 0.002″ per inch in the Z-direction, whichever is greater.
  • Danae chooses part orientation to maximize part quality unless otherwise specified.
  • Minimum resolvable feature size, including positive text features, is at least 0.035” (0.045” or greater is safest).
  • Theoretical maximum build volume of 24” x 36” x 36.”
  • Nylon 12 parts with thicker geometries, flat or broad parts, and parts with uneven wall thicknesses will be prone to significant deviations or warp due to variable thermal shrinkage and stress.

POLYJET

  • +/- 0.004″ for the first inch is typical, or +/- 0.001″ per inch, whichever is greater. Build area up to 19 x 15 x 7″
  • Theoretical maximum build volume of 19” x 15” x 7.”
  • Minimum feature size of 0.050” can be built with consistency.
  • Rubber-like materials represent an approximation of shore A values and may vary between geometries.

MATING PARTS

  • Danae, Inc. is not responsible for the fit of mating parts.
