Both processes utilize powder bed fusion without sacrificial support structures, but they use different heat fusing mechanisms. SLS uses a CO₂ or fiber laser to trace and sinter particles, providing exceptional mechanical resilience and superior tear resistance. MJF applies a liquid fusing agent and infrared lamp heating, resulting in denser parts, better gas/water tightness, and smoother as-printed surfaces. MJF parts are naturally charcoal grey and typically undergo graphite dyeing or vapor smoothing.

In powder-bed processes like SLS and MJF, preheating the build chamber to within a tight thermal processing window ensures nearly isotropic consolidation. Z-axis tensile retention routinely exceeds 85–90% of the X-Y plane values. For liquid or airtight applications, components undergo post-process chemical vapor polishing. The vapor smoothing reaction gently liquifies the outer surface layer, sealing micro-pores and boosting elongation-at-break performance.

Every shipment includes comprehensive quality assurance paperwork: full Coordinate Measuring Machine (CMM) dimensional verification, optical 3D scan comparison against your native CAD STEP files, raw material batch composition certificates (RoHS, REACH compliant), and Shore hardness durometer readings. We also provide signed non-disclosure agreements (NDAs) prior to receiving proprietary engineering designs.

Rapid prototyping orders (1–10 units) typically complete production within 48 to 72 hours. Low-volume batch runs (50–500 units) require 5–7 business days, including post-processing and QA inspection. Air freight via DHL, FedEx, or UPS Priority reaches Europe and North America within 3–5 working days, providing a dependable bridge during tooling changes or production delays.
