There are many different prototyping processes and each uses a specific material to achieve the desired end result.
We will guide you through the options to suit your project, but for your information, here is a brief look at the prototyping processes most commonly used.
3D Printing
Manufacturing prototypes from plaster using 3D Printing is the most cost-effective prototyping process available today. Each part or prototype is built by alternating a layer of plaster with a bonding agent. The finished part is then cleaned and impregnated with resin for strength. These parts can be readily "finished" to look like the end use product. Ideal for form studies, 3D printing is definitely the best solution for those on a tight budget.
FDM
Fused Deposition Modeling is a process where thermoplastic materials are extruded and deposited layer-by-layer, fusing each new layer to the one below. FDM prototyping and direct digital manufacturing systems create accurate, functional prototypes using a variety of high-performance engineering materials like ABS, polycarbonate and polyphenylsulfone. Capable of building parts up to 600x500x600mm in one piece, there is a wide variety of materials available in various colours. Popular for medical and automotive applications, FDM produces functional working prototypes suitable for form fit and function testing.
SLS
Selective Laser Sintering uses a computer controlled laser beam to fuse nylon powder in a process that bonds layer by layer. The benefits of SLS prototyping is that prototypes are produced in nylon and glass-filled nylon materials. These can then be used for functional testing, especially where chemical resistance is required. Nylon is a flexible material which allows for greater movement in the prototype which can be critical in some applications.
Objet
Objet printing is capable of building prototypes in a wide variety of hard plastics and soft rubber-like materials. You can also build in a combination of these by changing the percentage of each material to achieve the desired hardness and Shore factor. Basically, Objet printing is an additive process where a 3D picture is built using UV lights and UV sensitive materials. The benefits of this process are its wide variety of materials and colours as well as its ease in handling complex geometries and matrixes. Suitable for form, fit and function.
CNC
Computer Numerical Control (CNC) is the opposite of most rapid prototyping processes. Instead of being an additive process, it actually uses the selective removal of material to build your part. Building prototypes in Aluminium, Acrylic, Foam, Zinc, Nylon, Acetyl and Chemical Wood, CNC is ideal for testing product wear, snap features, durability and overall strength. A wide variety of finishes can also be achieved producing a prototype similar in appearance to the manufactured part.
Hand finishing and painting
Prototypes can be used in their "Natural" state or you can have them painted and finished to look like the end use product. Chrome plating is just one finishing technique we use to make plaster prototypes resemble their end use products.
