Metal 3D Printing Services
Rapidaccu delivers precision metal additive manufacturing using Direct Metal Laser Sintering (DMLS) and Selective Laser Melting (SLM) technologies. From aerospace-grade titanium to corrosion-resistant stainless steel, we produce complex metal parts with exceptional mechanical properties.
What is Metal 3D Printing?
Metal 3D printing, also known as metal additive manufacturing, builds parts layer-by-layer using high-powered lasers to fuse metal powder. This enables the creation of complex geometries, internal channels, and lightweight structures impossible with traditional manufacturing methods.
DMLS Technology
Direct Metal Laser Sintering uses precise laser beams to selectively fuse metal powder particles, creating fully dense parts with mechanical properties comparable to traditionally manufactured components.
Design Freedom
Create complex internal cooling channels, organic lattice structures, and topology-optimized designs that reduce weight while maintaining structural integrity.
No Tooling Required
Eliminate expensive tooling costs and long lead times associated with casting or machining. Ideal for prototypes, low-volume production, and custom parts.

Metal 3D Printing Advantages
Why choose metal additive manufacturing over traditional methods
Lightweight Designs
Topology optimization and lattice structures reduce weight by up to 70% while maintaining strength. Critical for aerospace applications where every gram counts.
Part Consolidation
Combine multiple components into a single printed part, reducing assembly time, eliminating fasteners, and improving reliability.
Rapid Prototyping
Go from CAD to metal part in days instead of weeks. Perfect for design verification, functional testing, and iterative development.
Conformal Cooling
Internal cooling channels follow part geometry for superior heat dissipation in molds, tooling, and thermal management applications.
Low-Volume Production
Economical for quantities from 1 to 1000+ parts without tooling investment. Scale production as demand grows.
Material Efficiency
Unused powder is recycled and reused. Minimal waste compared to subtractive manufacturing which can waste up to 90% of raw material.

Design Guidelines for Metal 3D Printing
Optimize your designs for successful metal additive manufacturing
Design Best Practices
- Minimum wall thickness: 0.4 mm for most metals, 0.6 mm for titanium
- Support structures: Required for overhangs >45°, consider orientation
- Holes and channels: Minimum 1 mm diameter, consider powder removal
- Text and engraving: Minimum height 0.5 mm, depth 0.5 mm
- Clearance gaps: Minimum 0.5 mm between moving parts
Common Design Pitfalls
- Avoid: Large flat surfaces parallel to build plate (causes warping)
- Avoid: Enclosed cavities without powder removal holes
- Avoid: Sharp internal corners (use fillets ≥0.5 mm)
- Avoid: Extremely thin features in unsupported areas
- Avoid: Threads smaller than M3 (post-machine instead)
