Stereolithography (SLA or STL) – a frequently used 3D printing process in rapid prototyping and additive manufacturing. The applications for stereolithography vary widely and range from the creation of design studies and functional prototypes to presentation models.
Especially in prototyping, stereolithography is ideal for product development. Why? SLA 3D printing is ideal for detailed models or small series as it delivers high precision, flexibility of component size, very good surface properties, a wide variety of available materials and fast delivery times.

Materials

Very precise models are created by photopolymerization from liquids because very little and finely focused laser radiation is used and the process-related shrinkage is very low. Different surface options are available as the materials are excellent for further processing after printing. Stereolithography allows you to produce transparent and translucent plastic parts.

Applications

  • Prototypes in product development
  • Master models for molding (vacuum casting)
  • Components with high precision
  • Design studies
  • Functional components
  • Presentation models
  • Direct production of casting tools

Finishing

1zu1 offers different quality levels of master models.
Why? To keep your development costs as low as possible. The following three factors are important:

  • Follow-up procedure (e.g. vacuum casting)
  • Quality required 
  • Intended purpose

The starting point for further processing is first of all to clarify the required type of post-processing. This depends on the rapid prototyping process used, the subsequent duplication process, the intended use and the material of the prototype or whether SLA components are used directly as series parts. 

Work steps

  • Removal of the remnants of the starting material
  • Cleaning of the component surfaces 
  • Chem. post-treatment with solvents (if necessary)

Assignment of work according to quality levels

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!

Systems

With its stereolithography systems, 1zu1 sets new standards in manufacturing – we use the best possible machines and the premium materials to achieve outstanding results in accordance with the most diverse customer requirements.
