sls: benefits and limitations
use the information below to answer the question.
benefits for sls

• since this is a robust process, and its good for complex forms, it can be used to create functional parts.
• no support structure is needed, which leads to more creative freedom.
• there is no detrimental effect or impact on the finish, which you find with fused filament fabrication or vat polymerization processes.
• it is good for aesthetic pieces and prototypes.
• the cost is relatively low.
• it has 30% volume and 70% mass.
• dye can be added to it, and it can be made water - resistant or water - proof.
• detail is quite high. it is very close to vat polymerization.
• it has excellent layer adhesion and is very dimensionally accurate.
• there is good tension strength in the layer axis.

in terms of the sls process, what is the ratio of volume and mass?
30% volume and 70% mass
50% volume and 50% mass
20% volume and 80% mass
40% volume and 60% mass

Explanation:

Step1: Identify the given values

The text states that SLS has 30% volume and 70% mass.

Step2: Calculate the ratio

The ratio of volume to mass is $\frac{30\%}{70\%}=\frac{3}{7}$. But looking at the multiple - choice options, we directly pick the option that gives the correct percentage values as stated in the text.

Answer:

30% volume and 70% mass
