Continuous numerical casting

It needs no electricity

It is always free to use

Designs can be edited quickly without redrawing

It removes the need for any design skill

Only printed in black and white

Rotated and viewed from any angle

Used without any computer

Drawn only in 2D

Build objects layer by layer

Turn cylindrical parts

Bend acrylic by heating

Cut and engrave flat sheet material

Removing material with a cutter

Adding material layer by layer

Pressing a sheet over a mould

Melting metal in a furnace

3D printing

Injection moulding

CNC routing or milling

Vacuum forming

Redrawn by hand for the machine

Only used for marketing

Sent straight to the CAM machine

Thrown away before manufacture

Each part is hand finished differently

Workers measure each part separately

The design changes each time

The machine repeats the same operation accurately

The same file can make one part or thousands

It can only make a single part

It needs no setup

It cannot be automated

Parts are always inaccurate

It cannot repeat operations

The machines and software are expensive

It only works on paper

A laser cutter

A CNC lathe

A 3D printer

A vacuum former

By testing the design by simulation on screen

By making more prototypes automatically

By printing the drawing on paper

By removing the design stage
