What Sandblasting does for 3D printed parts
Sandblasting is one of the 3D Plus hardware finishing services on AIHFABS. It is applied after printing so the part leaves production closer to a usable product—not only a raw build. Use this page to decide whether Sandblasting matches your cosmetic, durability, or assembly requirements before you upload a file.
Sandblasting, also known as abrasive blasting, is a post-processing technique that enhances the surface finish of printed parts by directing a stream of abrasive material at the surface under high pressure. Sandblasting effectively smooths out surface irregularities, removes support material residue, and provides an even, refined surface. It is a fast and efficient process that ensures surface consistency throughout the part.
Finishing is quoted with the print. Select Sandblasting in checkout, review price and lead time, and keep printing plus post-processing in one order instead of coordinating a second shop.
Why teams specify Sandblasting
Appearance
Sandblasting can hide layer lines, even out color, or create a more uniform surface for display models, consumer housings, and review samples.
Performance
Depending on the process, Sandblasting may improve wear, corrosion resistance, grip, or light diffusion so the part survives handling and end use.
Ready-to-assemble parts
When Sandblasting is combined with printing, you receive parts that are closer to install-ready, reducing secondary work in your own workshop.
How to order this finish
Ordering Sandblasting follows the same 3D Plus software flow as a standard print. You do not need a separate finishing RFQ for catalog options.
-
Upload the CAD file
Use STL, STEP, or another supported format. The quoter checks volume and geometry so finishing can be priced against the actual part.
-
Choose print process, material, and Sandblasting
Pick SLA, SLS, MJF, SLM, FDM, DLP, or CNC where applicable, then add Sandblasting and any other 3D Plus hardware options the part needs.
-
Compare price, lead time, and checkout
Review supplier options, confirm quantity, and place the order. Printing and finishing stay on one timeline and one invoice.
Compatible processes and design notes
Sandblasting is typically applied to plastics or metals produced with industrial 3D printing. Compatibility depends on material, wall thickness, and whether the surface can be reached by spray, media, chemistry, or tooling. Deep recesses, thin walls, and optical faces may need design review. If the automatic quote cannot apply Sandblasting to your file, request a manual quotation.
Need Sandblasting on a batch, a mixed-material assembly, or a part that also requires tapping or painting? Keep those options in the same quote so lead time includes the full stack of operations.
