Selective Laser Sintering (SLS) is a generative layer construction process and supports product development with its speed. The model is constructed via local sintering or melting of layers of powdered material using focused laser radiation. In this way, any three-dimensional geometries can be created without supports. With SLS, detailed functional prototypes or series can be produced very quickly, starting from batch size 1. This leads to an accelerated product development, a reduction in risks and a shortening of time to market.


Quality materials and perfectly maintained systems guarantee maximum dimensional and fit accuracy for your parts. Our high-tech systems only receive the best original materials, which we have extensively tested. Polyamide, glass-reinforced polyamide and polypropylene are currently available as laser sintering materials. Since many products are made from polypropylene, we consistently pursue our goal of getting “1-to-1” to the original. As a special technology, we also offer the material rubber and for particularly detailed applications FDR technology.

Surface finishes

Here at 1zu1 we can treat master models, duplicated parts and serial parts with special surface techniques according to customer requirements . We finish the prototypes and serial parts via EDM texturing, high gloss, special effects (metallic, silver, partial) or subsequent varnishing.

We can also accommodate individual color samples or color requests (RAL, NCS, Pantone). For this purpose, we offer a wide range of surface treatment processes in manual finishing, depending on the initial technology. Each process can be applied individually, in combination, partially or fully, according to RAL or NCS.

The possibility of individual printing, laser marking as well as hot foil stamping is also available at 1zu1 in-house. Put us to the test!

Design options and guidelines

Selective Laser Sintering is typically used for components with hard-to-reach areas, functional film hinges and undercuts. To enable us to manufacture these objects precisely and without problems, we have compiled a series of technical guidelines to support your design process.

Details of the design guidelines


Currently 10 SLS systems are available for plastic parts using different materials. We are continuously investing in new machine technology. On all machines, we can achieve construction layers of a maximum of 100 µm and a wall thickness of up to 0.45 mm. As a result, previously visible layers increasingly disappear; clean and smooth side walls are created, and fine or large parts can be produced with even greater precision. We work with all materials on a daily basis. Our standard lead time is 3 days. Larger dimensions or quantities on request.
