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 equipment guarantee the highest level of form and fit accuracy for your parts. Our high-tech equipment receives only the best manufacturer materials, which have been tested by us for a long time. Currently, you can choose from the laser sintering materials polyamide, polyamide with glass reinforcement, polyamide flame retardant and polyamide with carbon fibers. Because many products are made of polypropylene and we consistently pursue our goal to come 1-to-1 to the original, we also offer the material polypropylene PP01. As special technologies, the material rubber and, for particularly detailed applications, the FDR technology are also available.

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


At 1zu1

we currently have 13 SLS machines for plastics with different materials at your disposal. We are constantly investing in new machine technologies. On all machines we realize build layers from 40 - 100 µm and wall thicknesses from 0.22 up to 0.65 mm. Previously visible layers disappear more and more, clean and smooth sidewalls are created, fine or large parts can be produced even more accurately. We start daily with all materials. Our standard lead times are 3 days. Larger dimensions or quantities on request.
