SLM/DMLS can print walls as thin as 0.3mm. Recommended minimum for structural parts is 0.5-1.0mm.
Through holes as small as 0.3mm can be printed. Holes below 1mm may require drilling for accuracy.
3D printing excels at undercuts - no tool withdrawal issues. Complex internal geometries are a key advantage.
Complex internal channels, conformal cooling passages, and lattice structures are printed directly - no assembly needed.
Internal threads can be printed directly. External threads may need post-machining for precision requirements.
No draft angle required. Vertical walls print perfectly. Support structures handle overhangs automatically.
As-built tolerance of 0.05-0.15mm (SLM). Post-machining can achieve tighter tolerances for mating surfaces.
Layer-by-layer printing creates "staircase" effect. Ra 5-15μm typical for SLM. Polishing or machining can improve.
True additive manufacturing benefit. Gyroid, honeycomb, and custom lattices for weight reduction up to 80%.
Metal inserts can be placed during printing with careful pre-heating. Press-fit inserts are common practice.
Deep blind holes, bores, and channels are printed directly. No drill reach limitations or complex tooling.
Large flat areas perpendicular to build plate may warp. Optimize orientation or add stiffening ribs.
Build Orientation Matters: Optimize part orientation to minimize support requirements and reduce surface roughness on critical surfaces.
Support Structures: Overhanging features require support. Design for accessibility or consider splitting complex parts.
Wall Thickness Consistency: Avoid sudden thickness changes to minimize residual stress and warping.
Escape Holes: Add drain holes for unreleased powder inside closed cavities.
Embrace AM Design: Think differently - use lattice structures, conformal channels, and part consolidation.

Anodizing is the go-to treatment for AlSi10Mg. Creates hard, wear-resistant surface with optional color. E-coat provides excellent corrosion protection.
316L parts often used as-built or with passivation. E-coat for harsh environments. Polishing for medical/food applications.
Heat anodizing for color. Shot peening for fatigue improvement. PVD coating for wear resistance. Passivation for medical use.
Unlike CNC or casting, 3D printing requires no molds, dies, or fixtures. Design changes are free.
Price varies by material, size, and complexity. Complex parts may cost less than simple ones!
Small parts (50x50x50mm): from ¥50
Medium parts (100x100x100mm): from ¥150
Large parts (200x200x200mm): from ¥350
No MOQ. Order single prototypes or full production runs. Same quality at any quantity.
Design review, printing, and basic post-processing included
For batch orders. Larger quantities may require additional time.
Express (3-5 days) or standard (7-14 days) options available
Unlike traditional manufacturing where costs drop significantly with volume, 3D printing maintains relatively stable pricing. This makes it ideal for low-to-medium volume production.
Complex geometries, prototypes, aerospace/medical parts with lattices. SLM/DMLS recommended.
Functional parts, automotive brackets, tooling inserts. Consider binder jetting for cost savings.
