Additive Manufacturing

Question 1

Binder Jetting

Answer 1

Used inkjet style printing with powdered material (sand, ceramic, metal, plaster, ect) Instead of ink, it jets a binder that glues the powder together in the shape of the object. You can even use normal ink on the surface of the part to add color!

Question 2

Powder Bed Fusion

Answer 2

Similar to binder jetting - the difference is that rather than using a binder, a beam of energy is used to melt the material in the shape of the part. The energy beam is moved across the surface of the powder bed layer by layer.

Incudes SLS, DMLS and EBM.

Question 3

SLS

Answer 3

Selective Laser Sintering - usually polymers

Question 4

DMLS

Answer 4

Direct Metal Laser Sintering - specifically metal powder

Question 5

EBM

Answer 5

Electron Beam Melting - specific to metal like DMLS but uses an electron beam.

Question 6

HP MFJ

Answer 6

Multi Jet Fusion by HP - uses dark ink and radiant heating to bind the material - usually polycarbonate or nylon.

Question 7

Stereolithography/SLA

Answer 7

a form of 3D printing which makes solid parts from a liquid resin set by using ultraviolet light.

Question 8

Material Jetting

Answer 8

This method combines jetting technology with SLA technology. A photosensitive resin is jetted out of the print head, very quickly followed by a UV light. Can use multiple materials at once allowing easily removable supports. Often used for intricate models.

Question 9

Material Extrusion/FDM

Answer 9

Fused deposition modelling, also known as FFF (fused filament fabrication). If you’ve ever used a hot glue gun, FDM is very similar to this. Used most often in auto, aerospace and medical.

Question 10

OPEX

Answer 10

International Organization for Standardization -the money a company spends on an ongoing, day-to-day basis in order to run a business or system.

Question 11

MRO

Answer 11

Maintenance, repair and operations - the overhead costs for manufacturing companies. AM can significantly reduce MRO spending.

Question 12

ISB

Answer 12

Internal Service Bureau - a company that produces 3D printed parts for their own use, typically a manufacturer such as BMW, Decathlon, and Philips.

Question 13

ESB

Answer 13

External Service Bureau - A company that provides 3D printing as a service to other companies. Examples: Paragon, Prototal Sweden, Protolabs, and Voxeljet
