Industrial SLS 3D
Printing Service

Selective Laser Sintering (SLS) is a 3d printing technology ideal for producing highly complex parts from durable materials.

Technology Overview

By using a laser to selectively melt a 0.1 mm thick layer of nylon powder, our industrial SLS 3d printers build durable items with few design constraints. As the item is built on a bed of powder, unlike other 3d printing technologies, SLS 3d printers don’t require any support material and can therefore benefit from a complete freedom in terms of product design.

While the unprocessed items are white out of the printer, 3d printed nylon can easily be dyed, and we offer a wide range of colours to which we can dye your items.

Our SLS Machinery

Our SLS printing farm is based around a combination of proprietary machines and machines made by renowned german manufacturer EOS. Our automated machines are able to start new print-jobs 24/7 allowing true volume manufacturing using SLS 3d printing technology, therefore being an exceptionally cost-efficient method to go from prototyping to mass manufacturing.

Combined with our finishing systems for surface cleaning, treatment and dyeing, we use our SLS production systems to produce items with market-leading visual and mechanical properties.

SLS Materials

We carry two nylon-based materials for our SLS 3d printing service: PA12 and Alumide. With these materials combined with our post-processing and finishing systems, we are able to offer 3d printing services for a wide variety of applications ranging from visual prototypes to mass manufacturing of engineering items with strict mechanical requirements.

Nylon PA12

One of the most common grades of Nylon; PA12 has exceptional strength and toughness.
