Intro to Modeling and 3d Printing

What is the primary function of a 3D printer?

• To cut materials into specific shapes

• To engrave designs onto surfaces

• To create three-dimensional objects from a digital file

• To weld materials together

Which software is commonly used for creating designs for 3D printing?

• Microsoft Word

• Adobe Photoshop

• Tinkercad

• AutoCAD

Which software do we use with our laser macine?

• Lightburn

• Adobe Photoshop

• Tinkercad

• AutoCAD

What type of laser is typically used in laser engraving machines?

• X-ray laser

• CO2 laser

• Diode laser

• Fiber laser

What is the main advantage of using a laser engraver over traditional engraving methods?

• It is more expensive

• It is slower

• It allows for more precise control

• It can only engrave on metal

Which of the following materials can NOT be cut by a CO2 laser?

• Wood

• Acrylic

• Glass

• Polycarbonate

What is the significance of layer height in 3D printing?

• It determines the color of the final print

• It affects the print speed and quality

• It specifies the type of material used

• It controls the temperature of the print bed

Why is ventilation important when using a laser engraver?

• To cool down the machine

• To increase the speed of engraving

• To remove smoke and potentially harmful fumes

• To improve the accuracy of the laser

In Tinkercad, what is a "Workplane"?

• A tool for measuring objects

• The surface on which you build your design

• A feature to change the color of your design

• A command to duplicate your design

What does the term "slicing" refer to in 3D printing?

• Cutting the finished object out of the print bed

• Dividing the digital model into layers for printing

• Adjusting the size of the 3D model

• Applying a texture to the surface of the print
