3D Printing Process Characteristic

Release time:2024-03-18

	Advantages	Disadvantages	Typical accuracy	Typical layer height
SLA	• High resolution • No visible layer lines; smooth finish • Option of clear materials	• Printers more expensive than FDM • Weak parts; will degrade with sunlight • Extensive post-processing required	• ± 0.5% (desktop) • ± 0.15% (industrial)	• 25-100 microns
SLS	Parts have consistent mechanical properties • No support structures	• Porosity • Rough surface finish	• ± 0.3%	• 100-120 microns
SLM	• Strong and hard parts • Complex shapes	• Limited build size • High cost	• ± 0.1mm	• 20-50 microns
FDM	Most affordable 3D printing process for plastic parts Material options • Widely available	• Comparatively low resolution • Produces visible layer lines	• ± 0.5% (desktop) • ± 0.15% (industrial)	• 50-400 microns
