What We Do

What Is Post-Processing Service for 3D Printing?

Post-processing covers every finishing step performed after a part leaves the printer or machine: removing supports, sanding surfaces, applying coatings, or adding functional treatments like threading and heat treatment. It is the surface finishing service that turns a raw output into a part that is ready for real use.

As additive manufacturing moves from prototyping into full scale production, surface quality and dimensional accuracy matter more than ever. A raw 3D printed or machined part is rarely end use ready on its own. Our post-processing service bridges that gap.

At 3D Specialist, we take every component through a meticulous finishing workflow tailored to your material, application and aesthetic requirements, delivering parts that look, feel and perform to the highest standard expected of a professional surface finishing service.

Common Questions

FAQ

Can't find your answer?

Contact our team

We accept STL, STEP, STP, OBJ, 3MF, IGS, IGES, DXF, DWG, AMF, PDF, JPG, PNG and more. For complex assemblies, send us your native CAD files and our post-processing service team will review them directly.

Standard finishing such as sanding, polishing and painting typically takes 1 to 3 business days. Multi step processes like anodizing, plating or heat treatment may require 3 to 7 days depending on complexity and batch size. Rush orders can be arranged, contact us to discuss your timeline.

Absolutely. Many production parts require a sequence of treatments, for example sandblasting before anodizing, or threading after heat treatment. Our engineers plan the optimal sequence for your part and material as part of our surface finishing service.

We work with a wide range of materials including aluminium, steel, stainless steel, titanium, engineering plastics such as PLA, ABS, PETG and Nylon, resins, and composites. Material suitability varies by process, and our team will confirm compatibility when reviewing your quote.

Yes. Our post-processing service and surface finishing service are available for parts produced elsewhere, whether 3D printed, CNC machined or cast. Simply send us your parts along with your finishing requirements and we will provide a quote.

For aluminium parts, anodizing is typically the most effective and cost efficient option within our post-processing service, since it thickens the metal's natural oxide layer. For steel and other metals, plating or a protective coating may be more suitable. Tell us your material and operating environment and we will recommend the right finish.
