Digital Manufacturing. 3D Printing

What is the first step to create a 3D design?

• Buy a 3D design software

• Search for inspiration in existing designs

• Draw the design on paper

• Have a clear concept or idea of the object you want to design

The most common subtractive manufacturing tools are ...

• 3D printers, 2D printers, and multilayer extruders

• Hammers, screwdrivers and pliers

• Milling machines, lathes and laser cutters

• 3D printers, nozzles and hot extruders

What is the process of 3D printing?

• A method of 2D printing that uses special ink to create 3D effects

• An additive manufacturing technique that involves creating 3D objects by layering material

• A manufacturing technique that uses molds to create 3D objects

• A subtractive manufacturing process that uses a laser to carve the material

there are three distinct phases in three dimensional printing:

• Drawing, Cutting and Printing

• Design, Build and Printing

• Design, Slicing and Printing

• Drawing, Heating and Printing

What is a commonly used material in 3D printing?

• Wood

• Glass

• Metal

• PLA Plastic

What software is used to create 3D designs?

• Microsoft Excel

• AutoCAD, Blender, SketchUp, SolidWorks, etc.

• Adobe Photoshop

• Microsoft Word

What is the function of a slicer in the 3D printing process?

• Make the model bigger

• Convert the 3D model into printable layers

• Remove the layers from the 3D model

• Convert the model into a video file

What is the extrusion temperature in FDM 3D printing?

• The temperature at which the plastic filament cools

• The temperature at which it is printed in 2D

• The temperature at which the plastic filament is heated and melted

• The temperature at which the metal melts in 3D printing

What is the importance of the heated bed in 3D printing?

• Avoid the use of supports

• Prevent material deformation and improve adhesion to the base.

• Improve print quality

• Increase print speed
