Post Processing For 3D Printed Parts

In addition to 3D Printing Services, we offer Post-Processing for our manufactured parts. Post-Processing is a way of smoothing and/or strengthening your 3D printed part so that it looks as perfect and professional as possible.

Improved Strength

Geometry Improvement

High Surface Quality

Grit 3D offers a range of 3D printing post-processing techniques to help you get the best out of your 3D printed parts.

Priming & Painting

The first step of getting the 3D printed part painted in any color is priming. It helps create a flawless final surface for the painting process.

After priming, thin coats of paints are applied until your simple 3D printed part is transformed into a ready to display consumer product.

Key Features:

  • Enhanced look & feel
  • Smooth & even finish
  • Can be painted with multiple colors

Key Limitations:

  • Increased weight
  • Tolerances are altered
  • Process takes long time

Vapor Smoothing

It is the most popular post-processing technique for models printed with ABS material. The process involves treating 3D printed part in a closed environment which reacts with the outer layers of the model and melts it. This outer layer lines fade and a shiny look is revealed.

Key Features:

  • Shiny & glossy (Great for gifts)
  • Fast processing time

Key Limitations:

  • Affects the dimensional accuracy
  • Negatively impacts on the strength of the model
  • Works on ABS material only

Epoxy Coating

A two-part epoxy resin coat is applied to the 3d printed part in order to seal its surface. The airtight seal around the model does not only give it a shiny look but also increases its resistance to high temperatures and various chemicals. Highly suitable for components that will be exposed to harsh operating conditions.

Key Features:

  • Does not impact the tolerances
  • Provides an outer protective shell

Key Limitations:

  • Visible layer lines
  • Process takes long time

Sanding & Polishing

A surface finishing technique that begins with smoothing out and removing small imperfections from the model using industrial grade sand papers. A wide range of grit sizes are used consecutively until any sort of coat can be applied on the surface of the model.
Finally, for a mirror-like surface finish, a polishing compound is applied designed specifically for plastics and synthetics.

Key Features:

  • Mirror-like finish
  • Any roughest of part can be smoothened

Key Limitations:

  • Process takes very long time
  • Affects the dimensional accuracy
  • Difficult to reach some spots, especially small holes and undercuts
