About drei-de
drei-de is a 3D printing service founded in 2014, based in Wallisellen (Switzerland). The platform brings additive manufacturing processes such as SLS, SLA, FDM, MJF, SLM, SAF, Binder Jetting, MJM and DLP as well as vacuum casting and investment casting under one roof and provides over 100 materials – from standard and high-performance plastics (PA12, PA11, TPU, ULTEM, PEEK) to metals such as aluminum, stainless steel and titanium. In addition to printing, the service portfolio includes CAD design, 3D data preparation, 3D scanning with an accuracy of up to 0,025 mm, post-processing and finishing, as well as series production without tooling costs. Prototypes, functional parts, spare parts, architectural models and small to medium series are manufactured for mechanical engineering, medical technology, research, architecture, design as well as aviation and rail transport. Manufacturing is partly handled through a vetted partner network; drei-de remains the contracting party and central point of contact. More than 1'000 companies, including ETH Zurich, CERN and SBB, use the service.

Processes & Materials
Polyamide PA12
Standard material for SLS/MJF/FDM; biocompatible, food-grade and suitable for functional parts.
PA 11
For powder-based processes with consistent mechanical properties and heat resistance.
PA-GF (glass-filled)
Polyamide with glass particles for higher heat resistance up to 110 °C.
Thermoplastic Polyurethane
Elastic, wear-resistant and impact-resistant, even in cold conditions.
ULTEM 9085
Flame-retardant high-performance thermoplastic (UL 94 V0) for aviation and industrial applications.
Aluminum
For SLM metal printing and investment casting of highly stressed, heat-resistant components.
Stainless Steel (316L)
Stainless steel alloy for corrosion-resistant metal components in the SLM process.
Titanium (Grade 5)
Lightweight, high-strength material for demanding metal printing applications.
Quartz Sand SH-F01
Binder Jetting sand for large components and sand casting molds.
AE12+ / AE21 (PMMA)
Acrylic glass materials via Binder Jetting, especially for very large components.
Accura / TuskXC2700T
Resins for SLA with smooth surfaces and high level of detail.
ProtoFlex / MG804
Vacuum casting materials for near-series small batches from silicone molds.

Quality
Every model is analyzed for feasibility before production. Depending on the process, tolerances of ±0.1 mm (industrial up to ±0.3 % or DCTG 8) as well as standards such as ISO 2768-m are maintained; before every print, the customer receives a 3D visualization that can be measured online.
