4 - 3D Printing Process

What is the primary material used in Stereolithography (SL)?

• Photopolymer resin

• Powdered metal

• Thermoplastic filament

• Standard copier paper

Which 3D printing process uses an arc lamp as a light source?

• DLP

• SL

• Laser Sintering

• EBM

What is the main advantage of DLP over SL?

• Faster processing due to single-pass light application

• Higher accuracy

• Better surface finish

• No need for support structures

Which process uses powdered materials and a laser to fuse particles together?

• Laser Sintering

• Material Jetting

• SDL

• FDM

What is the most common material used in entry-level FFF 3D printers?

• ABS and PLA

• Photopolymer resin

• Powdered metal

• Ceramics

Which 3D printing process can produce full-color parts using a CYMK palette?

• SDL

• Binder Jetting

• Material Jetting

• Laser Sintering

What is the heat source used in Electron Beam Melting (EBM)?

• Electron beam

• Laser

• Arc lamp

• Incandescent cathode

Which process involves selectively applying adhesive to standard copier paper?

• SDL

• LOM

• Material Jetting

• Binder Jetting

What is a limitation of the SDL process compared to other 3D printing methods?

• Limited build size

• Requires post-processing

• Cannot produce full-color parts

• Uses powdered materials

Which process allows simultaneous deposition of multiple materials with different properties?

• Material Jetting

• Binder Jetting

• Laser Sintering

• FDM
