3D Printer London

     3D printing is a form of rapid prototyping that can produce real 3D objects you can hold in your hand. 3D printers have been developed a lot more over the last ten years where the software and manufacturing processes have been adapted and changed for ease of use and for faster and cheaper purposes.

Printing in 3d can turn sketched models and CAD designs in programs into finished prototypes for 3D savvy customers wanting to hold a real object in their hand.

Creating these types of 3D printing techniques has allowed for easy prototype creation of products so they can be tested for size and functionality. There are a few different types of materials you can use when you create these products. There are plaster based materials that you can use to print and find out sizes and shapes for your 3D printing final product. These also still allow you to print in full colour to give you an aesthetic idea to the product.
There is also a high strength semi-translucent plastic material, ideal for fine detail and functional testing of products and prototypes that a company may want to test for new products and functional items they are hoping to sell.

Some 3D printers have been created to make quite large items such as the ZCorporation 450 printer that has a build size of 203 x 254 x 203mm. The Pro Jet 3000 has two build modes, high definition (HD) and ultra high definition mode (UHD).

In HD mode the build size on a printer is 298 x 185 x 203mm. In UHD mode it is 127 x 178 x 152mm. Producing parts outside these boundaries can be achieved by splitting the model into sections, printing them, and bonding together. These are so you can make larger scaled models and prototypes of bigger objects.

3D scanning techniques also allow for small models, replicas or CAD design of models.
Formatting your files into the correct files is key to get the right outcome of the product you want. Here is a list of the best types of files to use and what for.

.STL Widely used for rapid prototyping, this stereo lithography format is best for creating meshed data
without colour information.
.VRML Stands for Virtual Reality Modelling Language, this format support models with colour and texture.
.ZPR Designed by ZCorporation, this format where possible should be used for data containing colour and texture.
.3DS Commonly used in 3D Studio Max for parts containing colour and texture.
.OBJ Widely accepted format that can carry colour and texture information.
.ZCP & .PLY Commonly describes parts produced by 3D Scanners that contain colour, texture and geometry.
