Table 1.

Materials and main advantages of 3D printing technologies. The table shows three kinds of 3D printing technologies and their respective classification, materials, and main advantages.

Techniques	Classification	Materials	Advantages
Powder bed fusion	SLM		Require no debinding process [1]
	SLS	Metal materials [2]	Suitable for metal [3]
	EBM
	DMLS		Produce dense end-products [4]
Light curing	SLA		Good mechanical resistance [5]
	DLP	Resin [6], ceramic [7]	Reduced construction time [5]
	PJ		Higher surface quality of manufactured objects [7]
Fused deposition modeling	Thermoplastic materials [3]		Biocompatible and high mechanical strength of fabricated scaffolds [8]
