How rapid prototyping works

Rapid prototyping developed as an outgrowth of liquid photopolymer research, a class of plastics that solidify under high intensity ultraviolet laser light. Early RP methods where SLA's or stereolithography. Fused Deposition Modeling (FDM) is a newer approach that opened up a wider range of materials including polycarbonates, ABS plastics, and others. eMachineShop offers FDM Fused Deposition Modeling which uses a heated nozzle to extrude plastic onto a work piece. In this manufacturing process fused plastic is deposited layer by layer according to the 3D model.


Rapid prototyping typically produces low quantities of parts without tooling so that fast turnaround and low cost is possible. RP allows engineers, designers, managers and end users to check designs for usability, appearance, manufacturability, fit, function, etc., prior to committing to conventional manufacturing. RP speeds the design cycle. 


Almost any 2D or 3D shape can be made including shapes that cannot be made using conventional machining. Examples of a few applications include: EnclosuresBracketsToy Parts, Mechanisms, Shape models, etc.

Cost reduction

Ways to reduce cost include: reducing the weight of the final part and using proper part orientation. For example building a cup oriented in the normal way is more economical that building a cup oriented upside down.

Rapid Prototyping Design Considerations

The following applies to eMachineShop rapid prototyping:

  • Max size: 6" x 6" x 6".
  • Intricate features under ~1/16" such as small holes or small lettering are not possible.
  • Large holes or cutouts in side views can be problematic.
  • Material will be slightly porous and therefore is not appropriate for containers of gases or liquids.

Note: In the eMachineShop CAD software, choose Job | Materials | ABS and enable the corresponding option in Job | Settings | Specifications: Auto | Process permissions.

Video Tutorial

"I am in awe at the usability and intuitive interface. Great work, I can't wait to build a few prototype fixtures. I was in need of a CAD program for a new netbook I recently purchased; was at home and needed to flesh out some ideas. One quick download, and in less than 15 minutes I had a good working diagram. The eMachineShop was perfect for my ..."
