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
