Inkjet Similar to conventional inkjet printing technology using a photopolymer. Addition of an elevator enables the third axis of printing. Can provide exceptional speed and accuracy with surface finishes that require only light finishing when you paint the part. Limited proprietary material selection. LENS Laser engineered net shaping uses a laser to melt a substrate.
Metal powder is introduced into the void, melted, and then solidified.
Injection molds can incorporate efficient cooling channels that would be impossible to machine. Less accurate than others. In laminated object modeling, sections of a part are cut from paper and automatically glued together. Quickly models parts with strength and properties similar to wood. Accuracy of unsealed parts can be susceptible to changes in humidity.
