What Is 3D Printing
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.
Integrated 3D Printing and CNC Machining Solutions
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.
- Hybrid Workflow – 3D printed parts are post-machined for improved dimensional accuracy and surface finish.
- Seamless Integration – Seamlessly integrate printed plastics or metals with CNC milled components in complex assemblies.
- One-Stop Manufacturing – From prototyping to final inspection, every step is handled in-house at FastPreci.
Our 3D Printing Capabilities
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 3D Printing
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 3D Printing
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 3D Printing
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.
