How 3D printing works
3D printing developed as an outgrowth of liquid photopolymer research, a class of plastics that solidify under high intensity ultraviolet laser light. Early 3D printing methods were 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.
3D printing, also known as rapid prototyping, typically produces low quantities of parts without tooling so that fast turnaround and low cost is possible. 3D printing allows engineers, designers, managers and end users to check designs for usability, appearance, manufacturability, fit, function, etc., prior to committing to conventional manufacturing. 3D printing 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.
3D Printing Design Considerations
The following applies to eMachineShop 3D printing:
Parts must stay within these size parameters: 650 x 350 x 550 mm | 230 x 180 x 320 mm | 200 x 150 x 150 mm
Walls must be thicker than 0.7 mm.
Large holes or cutouts in side views can be problematic.
Keep embossed and engraved details above 0.2 mm high & wide.
Material will be slightly porous and therefore is not appropriate for containers of gases or liquids.
Clearance between part features must be greater than 0.5 mm.
