Additive Technologies 3 - Binder Jetting

True or false?

During binder jetting, a powder is deposited unto a liquid binder, resulting in particle agglomeration.

• TRUE

• FALSE

Which of the following is NOT a step in binder jetting?

• Binder droplets are deposited unto powder particles

• A laser is passed over the bed in order for powder particles to fuse together

• The printed object remains in the bed post-printing in order for the binder to fully set

• The printed object is then sintered in a furnace

What is the primary purpose of the binder in binder jetting?

• To provide structural support during printing

• To melt the powder particles

• To cool down the printed object

• To act as a catalyst for chemical reactions

Which material is commonly used as a binder in binder jetting?

• Water-based solutions

• Metal alloys

• Thermoplastic polymers

• Carbon fibers

True or false?

Binder jetting can be used to create full-color 3D prints.

• TRUE

• FALSE

What is the MAIN purpose of infiltrants used in binder jetting?

• To support the structure during building

• To bind powder particles together

• To improve the mechanical properties of the printed object

• To absorb heat upon irradiation with infrared light

Which of the following materials can be used as a powder in binder jetting?

• Plastics

• Metals

• Ceramics

• All of the above

True or false?

Binder jetting is an additive manufacturing process that does not require a heat source during the printing phase.

• TRUE

• FALSE

What is the role of the powder bed in binder jetting?

• To provide a base for the binder to be deposited

• To act as a support structure for the printed object

• To cool down the printed object

• To fuse the powder particles together

What is the primary advantage of binder jetting over other additive manufacturing processes?

• Higher resolution

• Faster production speed

• Lower material cost

• Better surface finish
