Process	Materials	Max build size	Typical tolerance	Best for
SLSSelective Laser Sintering	Nylon 11 · Nylon 12 · glass-filled · carbon-fibre Nylon 6	up to 910 × 430 × 400 mm^CONFIRM	±0.3% typical*	Functional prototypes, end-use parts, large formats, living hinges
MJFHP Multi Jet Fusion	PA 12 (HP-certified)	380 × 284 × 380 mm	HP-published tables*	Production batches, fine detail, consistent mechanicals
PolyJetStratasys J-series	Full-colour multi-material resin	1,174 cm² tray × 190 mm H	±0.15% (1σ, rigid)	Full-colour models, medical & consumer look-like prototypes^CONFIRM

* Typical achievable values for well-designed parts, as commonly quoted by major service bureaus; HP publishes per-material tolerance tables for MJF. Tolerance for your specific geometry is confirmed at quote — ask our engineers. Lead times quoted per part; we don't publish one-size-fits-all estimates.
