While vapor smoothing itself does not apply a color to the part, it makes the colors of the part more vibrant — so black dyed parts become a deeper, glossier black. Note that gray (raw) MJF parts will turn a near-black if vapor smoothed, as the gray surface melts into the black interior of the part during the process

About the Process

Vapor smoothing is a finishing process for 3D printed parts that uses a vaporized solvent to smooth the surface of a printed part without adding or removing material. The process is a controlled chemical melt that reduces the variation of peaks and valleys found on the surface of any printed part. It is used to reduce or remove visual layer lines and natural imperfections that occur during printing, leaving a smooth, glossy finish.

Along with improved cosmetic qualities, vapor smoothing seals the part’s surface and improves the mechanical properties of the part by filling in microfractures and other potential points of failure if the part is put under stress. 

Design considerations

  • Parts with uniform wall thicknesses will generally smooth more evenly
  • Radiused corners generally produce better results than sharp corners 
  • Wall thicknesses less than 1.5mm do not processes as uniformly
  • Parts usually need to be hung in the smoothing chamber, so expect hook marks — though we use existing holes and try to mitigate hook marks as much as possible

Material Options for Stereolithography (SLA) 3D Printing

Stereolithography (SLA), the technology used to produce them, supports the creation of plastic parts with tight tolerances, intricate geometries, and smooth surface finishes. And parts printed using SLA stand out because of their exceptional accuracy, resolution, and level of detail. One key advantage of SLA is its ability to achieve finishes that are both highly […]
