Selective Laser Sintering (SLS)

Laser Sintering (SLS) is the second most commonly used process after Stereolithography (SLA). Whilst accuracy and surface finish are not as good, the real benefit is the functionality that can be achieved.

CNC Machining

A major advantage in using machining as a prototyping or production technique is the huge range of materials that are available. In comparison additive manufacturing  (AM) materials have to go through a long evaluation prior to being released and are usually specific to a process.

Regularly sourced materials include, but are not limited to:



POM (Acetal)

PMMA (Acrylic)



PA (Nylon)

GFN (Glass filled Nylon)




These materials are sourced as extruded slabs in varying thicknesses. Sometimes the available thickness will force a part to be fabricated. This is seldom a problem unless the material is also one that is difficult to bond, such as PP.

Some materials take a very good finish, such as Acetal or ABS. Others, typically the softer materials like PP, are not so good.

Some materials like ABS will take a good painted finish, others like PP or PTFE cannot be painted effectively.

Colours are usually natural and in some cases black (eg acetal, PP, ABS).

Please contact Plunkett Associates directly if there is a specific material that you require.

3D Printing

This process uses many different materials that can be digitally combined to offer a range of properties. These range from ‘abs like’ to clear and flexible. As the options are so diverse, it is strongly suggested to contact Plunkett Associates with your application and we will ensure a suitable material(s) is proposed.

The process can build at either 16 micron or 30 micron layers, offering two price/quality options.

Further both hard and flexible materials can be built at the same time offering a one piece overmoulded prototype.

Vacuum Casting

Vacuum casting materials are generally polyurethanes (PU’s) although it is possible to cast some nylons. The range of materials is huge and as such it is impossible to provide a comprehensive list. The best advice is to contact Plunkett Associates with the following information, and we will identify suitable materials.

-       production intent material, ie abs or pc like

-       any environmental requirements, especially temperature

-       aesthetic requirements, colour, texture, printing

-       clarity or hardness if required
