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 having a 0.01" diameter 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: Enclosures, Brackets, Toy Parts, Mechanisms, Shape models, etc.
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 RP:
- Extrusion diameter (D) .01"
- Tolerance: +/- 1D.
- Min hole diam: 5D
- Min wall: 3D
- Min cylinder protrusion: 5D
- Min wall thickness with no holes or cutouts: 3D; with holes or cutouts: 10D
- Min height of horizontal slots in side of part: 25D
- Min material between hole and edge or between holes: 4D
- Min acute angle: 30 deg.
- Max size: 5" x 5" x 5".
- Material will be slightly porous and therefore is not appropriate for containers of gases or liquids.
- Surface roughness: ~1,000 Ra for .01" extrusion, ~2,000 for .02" extrusion.
- Small gaps may occur at intricate or curved features.
- Intricate features, such as small lettering are not recommended.
- To thread holes, use Line | Machine | Thread.
