The table below identifies the form of raw material used in two different rapid prototyping processes.
| Rapid Prototyping Technique | Form of Raw Material |
|---|---|
| Selective Laser Sintering (SLS) | Fine powder |
| Stereolithography (SLA) | X |
Identify the material that correctly completes position X in the table.
Which of the following rapid prototyping techniques is best suited for creating highly detailed models by curing liquid photopolymer resin with a UV laser, layer by layer?
Which rapid prototyping technique creates a 3D model by bonding together and cutting successive layers of paper or plastic?
A rapid prototyping technique is selected for a project based on the specific process characteristics summarized in the table below:
A design team is producing a functional prototype that includes complex overhanging features and internal voids. Which rapid prototyping process is most advantageous in this scenario because the un-fused build material provides natural support for the part during construction?
