3.2 Specialist design principles

A range of tools, equipment and processes that can be used to shape, fabricate, construct and assemble high quality prototypes, as appropriate to the materials and/or components being used including:

wastage, such as:

• die cutting

• perforation

• turning

• sawing

• milling

• drilling

• cutting and shearing

addition, such as:

• brazing

• welding

• lamination

• soldering

• 3D printing

• batik

• sewing

• bonding

• printing

deforming and reforming such as:

• vacuum forming

• creasing

• pressing

• drape forming

• bending

• folding

• blow moulding

• casting

• injection moulding

• extrusion.

• Papers and boards (offset lithography and die cutting).

• Timber based materials (routing and turning).

• Metal based materials (milling and casting).

• Polymers (injection molding and extrusion).

• Textile based materials (weaving, dying and printing).

• Electrical and mechanical systems (pick and place assembly and flow soldering).

The application and use of quality control to include measurable and quantitative systems used during manufacture

• Papers and boards (registration marks).

• Timber based materials (dimensional accuracy using go/no go fixture).

• Metal based materials (dimensional accuracy using a depth stop).

• Polymers (dimensional accuracy by selecting correct laser settings).

• Textile based materials (dimensional accuracy checking a repeating print against an original sample).

• Electrical and mechanical systems (UV exposure, developing and etching times in PCB manufacture).
