Technical Data Sheets

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.

Alumide

Polyamide with aluminium filler giving a light grey material.

Duraform EX

Manufacture tough, impact-resistant plastic prototypes or end-use parts requiring molded-part performance andcapable of withstanding harsh enviroments.

Duraform GF

Glass-filled polyamide (nylon) material for real-world physical testing and functional use.

Duraform PA

Durable polymide (nylon) material for real-world physical testing and functional use.

Duraform ProX AF+

An aluminum lled nylon 12 plastic that produces parts with high stiffness and a metallic appearance.

PA 3200 GF

Glass filled fine polyamide offering increased stiffness over PA 2200.

PA 2200

Fine polyamide for general application.

PP S5500P

Polypropylene material with high flexibility and toughness.

Windform XT 2.0

The material allows for the creation of accurate, reliable, and durable prototypes and is perfect for functional applications.

Stereolithography (SLA)

The 'original' Rapid Prototyping process; offers good dimensional accuracy and a large range of materials.

Accura 25

Flexible plastic to simulate and replace CNC-machined white polypropylene articles.

Accura 55

Rigid and strong plastic to stimulate and replace CNC-machined white ABS articles

Accura ABS Black (SL7820)

Rigid and tough, black ABS like.

Accura Xtreme

Ultra tough grey plastic to replace CNC machined polypropylene and ABS articles.

Accura Xtreme White 200

Look and feel of a durable moulded plastic with outstanding durability and impact resistance.

Somos Taurus

An extremely durable and high temperature resistant material that makes it ideal for the most demanding functional prototyping.

Somos 9120

Produces robust, functional and accurate parts with superior chemical resistance.

Somos EvoLVe 128

Produces accurate, high-detailed parts, designed for easy finishing for functional testing.

Somos NeXt

Extremely durable resin that produces very accurate parts with high feature detail.

Somos PerFORM

Creates strong, stiff, high temperature resistant composite parts.

Watershed 11120

Nearly colourless, low viscosity liquid photopolymer that produces strong, tough, water-resistant, ABS-like parts.

Watershed XC 11122

Clear, near colourless, durable, water-resistant resin.

MicroFine Green Resin

An opaque green, ABS-like material, formulated for micro-resolution stereolithography

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:

ABS

PC

POM (Acetal)

PMMA (Acrylic)

PBT

PTFE

PA (Nylon)

GFN (Glass filled Nylon)

PEEK

PVC

Ultem

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
