DESIGN GUIDE

3D Printing Design Guidelines

Optimize your designs for the best printing results

Wall Thickness

  • SLA: Min 0.5mm, Rec 1-2mm
  • SLS: Min 0.7mm, Rec 1.5-3mm
  • SLM: Min 0.4mm, Rec 0.8-2mm
  • Avoid large thin walls

Support Structures

  • Overhangs >45° need support
  • Bridges >5mm need support
  • Design self-supporting when possible
  • Optimize orientation

Tolerances

  • Clearance fit: 0.2-0.3mm
  • Transition fit: 0.1-0.15mm
  • Threads: Allow for post-machining
  • High-precision faces may need finishing

FAQ

Frequently Asked Questions

Answers to common 3D printing questions

3D printing can create almost any geometric shape: prototypes, functional parts, molds, artwork, medical devices, architectural models, jigs & fixtures. From simple concept models to complex industrial components.

SLA: ±0.05mm precision, 0.025mm layer height. SLS: ±0.1mm for functional parts. SLM Metal: ±0.05-0.1mm for industrial components. We recommend the best technology based on your requirements.

Standard prototypes: 24-48 hours. Complex parts or batch orders: 3-7 business days. Metal 3D printing: 5-10 business days. Express service available: 4, 8, or 12 hours for urgent orders.

STL, OBJ, AMF, 3MF, STEP, IGES, and major CAD formats. STL (.stl) or STEP (.stp/.step) recommended. Contact our engineers if unsure about file compatibility.
