Turn complex designs into custom 3D printed parts with FastPreci. Enjoy tight tolerances, advanced materials, and expert guidance for every project.
3D printing, or additive manufacturing, builds parts layer by layer directly from digital CAD models. It enables complex geometries and internal structures that are difficult to achieve with traditional methods, while reducing tooling costs and supporting rapid turnaround.
By supporting rapid prototyping, functional testing, and small batch production, 3D printing accelerates product development. At FastPreci, this technology is often combined with CNC machining to achieve higher precision and refined surface quality.
At FastPreci, additive manufacturing and CNC machining work hand in hand. We combine the design freedom of 3D printing with the accuracy and surface quality of CNC machining to deliver production-ready parts — faster, smoother, and more precise.
FastPreci provides a range of 3D printing services to transform CAD designs into functional prototypes and end-use parts. Our engineers guide the choice of the most suitable technology and material, ensuring accuracy and reliability.
SLA (Stereolithography) uses a laser to cure liquid resin into solid parts with high precision and smooth surfaces. FastPreci employs SLA for detailed prototypes and intricate designs.
SLS (Selective Laser Sintering) fuses nylon powder layer by layer with a laser to create durable parts without support structures. FastPreci uses SLS for functional prototypes and small batch production.
MJF (Multi Jet Fusion) uses a layer-by-layer powder fusion process with binding agents and heat to produce strong, precise parts. FastPreci applies MJF for functional prototypes and production-ready plastic components.
SLM (Selective Laser Melting) is a great option for low volume plastic parts that simulate injection-molded quality. Smooth surfaces and consistent dimensions make it ideal for appearance and functional testing.
FDM (Fused Deposition Modeling) extrudes thermoplastic filaments layer by layer to build parts. FastPreci applies FDM for cost-effective structural prototypes and early-stage design verification.
