This document discusses 3D printing methods, comparing inkjet printing which is fast and can print in color, photopolymer printing which uses UV lights, and laser sintering which shoots a laser and has a removable binding layer, noting laser sintering is more expensive but can create larger models. It also lists the advantages of 3D printing as being less expensive and taking less time than making models by hand, while disadvantages are the costs of the printer and the time required for printing.

2.  Like injet printers
 Fastest method
 Only method that can fully print out in
color

4.  Like photopolymer
 Uv-lights

5.  Shot by a laser

6.  Binding layer is removable after the
creating
 More expensive printer  dissolve in a
liquid

7.  = normal method
 Purpose : serve a bigger model

8. Disadvantage s Advantages
expensive Costs less than making it yourself
Takes a lot of time Less time than making it yourself
