Mold making with 3D printing - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is mold making with 3D printing?

Mold making with 3D printing is the process of creating molds using a 3D printer. These molds can then be used to shape materials like plastic, resin, or metal into desired forms.

beginner

Name one common material used for 3D printed molds.

One common material used for 3D printed molds is resin, especially in SLA (Stereolithography) printing, because it can create smooth and detailed surfaces.

intermediate

Why is 3D printing useful for mold making compared to traditional methods?

3D printing allows for faster, cheaper, and more customizable mold production. It can create complex shapes that are hard to make with traditional mold-making techniques.

intermediate

What is a limitation of using 3D printed molds?

3D printed molds may not be as durable as metal molds and can wear out faster, especially when used with high-temperature or abrasive materials.

beginner

How can 3D printed molds be used in real life?

They are used for making prototypes, small production runs, custom parts, jewelry, dental molds, and even in art projects where unique shapes are needed quickly.

What is the main benefit of using 3D printing for mold making?

A Requires no design work

B Molds last forever without wear

C Faster and more customizable mold production

D Only works with metal materials

3D printing allows molds to be made quickly and customized easily, unlike traditional methods.

Which 3D printing material is often used for smooth and detailed molds?

A Resin

B Wood filament

C PLA plastic

D Concrete

Resin, especially in SLA printing, creates smooth and detailed molds.

What is a common limitation of 3D printed molds?

A They wear out faster than metal molds

B They are too heavy

C They cannot be customized

D They only work with water

3D printed molds usually wear out faster than traditional metal molds.

Which of these is NOT a typical use of 3D printed molds?

A Making jewelry prototypes

B Mass production of car engines

C Dental molds

D Art projects

Mass production of car engines usually requires durable metal molds, not 3D printed ones.

What technology is commonly used to print detailed molds with resin?

A Inkjet printing

B FDM (Fused Deposition Modeling)

C Laser cutting

D SLA (Stereolithography)

SLA uses resin and a laser to create detailed and smooth molds.
