Abstract: The current 3D printing materials were categorized to two types: organic and inorganic materials, the former included acrylonitrile-butadiene-styrene copolymer, poly(lactic acid), polyamide resin, photosensitive resin and hydrogels; the latter included titanium alloy, ceramics, gypsum, etc. Furthermore, efforts were made on summarizing properties, advantages, and disadvantages of different types of 3D printing materials. The developing trend and perspective of 3D printing materials were also discussed.

Key words: three dimensional printing material, photosensitive resin, inorganic material, research progress
