3D Design and Printing Quiz

The plastic used in 3D printing is very tough, hard and rigid. It can withstand high temperatures and is easy to paint. It is very resistant and has some flexibility. We are talking about...

• Polyethylene

• Polypropylene

• ABS

• ABL

The most flexible plastics are called...

• Blow moulding

• Injection moulding

The procedure used to form bottles is...

• Extrusion

• Blow moulding

• Injection moulding

Polyester resins and Bakelite are…

• Thermoplastics

• Thermosets

• Elastomers

• The first is an elastomer while the second is a thermoplastic

Plastics identified with RIC code 7...

• Are easily recyclable.

• Are very difficult or impossible to recycle.

The most common elastomers include:

• Bakelite, polyethylene and neoprene

• Rubber, neoprene and silicones

• Silicones, polyester resins and PVC

• ABS, rubber and HDPE

The main parts we find inside 3D printers are:

• Nozzle, extruder and filament

• Extruder, mechanics and electronics

• Filament, electronics and extruder

• Extruder, nozzle and hot-end

When we begin with a block or bar material and gradually remove the excess until we end up with our desired form, we call it

• Prototype

• Additive manufacturing tools

• CAD (Compter Aided Design)

• Subtractive manufacturing tools
