SLS & SLM Printers Quiz

How does Selective Laser Sintering (SLS) differ from Selective Laser Melting (SLM)?

• SLS uses a laser, while SLM uses a printer head

• SLS is used for metals, while SLM is used for plastics

• There is no difference between SLS and SLM

• SLS fuses powders without melting them completely, whereas SLM melts the powders entirely

Which of the following materials is commonly used in SLS printing?

• Liquid resin

• Metal sheets

• Nylon powder

• Wood chips

What is a key advantage of using SLS printers in manufacturing?

• They can create very complex geometries

• They require no post-processing

• They only work with a single type of material

• They are faster than all other types of 3D printing

In SLS printing, what role does the laser play?

• It cuts the material into the desired shape

• It cools the material to harden it

• It heats the powder to fuse it together layer by layer

• It paints the final object with colors

Which of the following powders is NOT typically used in SLS printers?

• Polyamide (nylon)

• Sand

• Carbon fiber

• Flexible (soft material)

Why might a manufacturer choose SLS over traditional manufacturing methods?

• SLS is cheaper for large-scale production

• SLS doesn't need support structures

• SLS can only produce small, simple parts

• SLS has fewer material options

What is a common use for SLM printers?

• Creating high-strength metal parts for aerospace applications

• Printing prototypes with rubber-like flexibility

• Producing large-scale architectural models

• Printing on fabric

What is a potential drawback of using SLS printers?

• Limited material reuse

• Slow printing speeds

• High cost of materials

• Inability to produce detailed parts

How are unused powders typically handled in SLS printing?

• They are discarded as waste

• They are filtered and reused for subsequent prints

• They are melted down for future use

• They are compressed into solid blocks

What is the primary function of a Selective Laser Sintering (SLS) printer?

• To melt metal powders completely

• To fuse powdered materials using a laser without complete melting

• To print on paper using powdered ink

• To engrave designs on wood
