A short clip on how the Sinterit Sandblaster works. This Sandblaster abrasive material used to clean, smooth and finish your SLS 3D printed parts in the Sinterit Sandblaster. Thanks to some compressed air and little glass balls (Abrasive Material) using Sandblaster you can penetrate all of the corners of your model and highlight every detail.

Are you searching for an efficient, precise, and automated way to post-process your 3D printed parts? Look no further than the Sinterit Sandblaster. In this article, we'll explore the ins and outs of this impressive device, its benefits, applications, and the different models available on the market.

What is Sinterit Sandblaster?

The Sinterit Sandblaster is a post-processing machine designed specifically for SLS (Selective Laser Sintering) 3D printed parts. It uses abrasive blasting to remove residual powder and create a smooth, polished surface on the printed parts.

How does Sinterit Sandblaster work?

The Sinterit Sandblaster works by blasting abrasive media, such as aluminum oxide or glass beads, at high velocity onto the surface of the 3D printed part. This process removes any excess powder and smooths out surface imperfections, creating a professional-looking, high-quality finish.

Benefits of using Sinterit Sandblaster

There are several advantages to using the Sinterit Sandblaster for post-processing your 3D printed parts:

Improved surface quality

The abrasive blasting process results in a smooth, polished surface that is free of residual powder and surface imperfections.

Faster post-processing

Compared to manual methods, the Sinterit Sandblaster significantly speeds up the post-processing time, allowing you to finish more parts in less time.

Enhanced durability

By removing excess powder and creating a uniform surface, the Sinterit Sandblaster can improve the overall strength and durability of the finished part.

Greater design freedom

Thanks to its precise and automated process, the Sinterit Sandblaster can handle complex geometries and intricate designs that would be challenging or time-consuming to post-process manually.
