3D Printing Case Study

Here is a nice example of a large part made in smaller sections.

Sometimes we need to make parts which are too large for our 3D printer. In this case we can split the part up into manageable sections, print them out, and glue them together.

What is 3D printing?


First, the 3D Printer spreads a thin layer of powder. Second, an ink-jet print head prints a binder in the cross-section of the part being created. Next, the build piston drops down, making room for the next layer, and the process is repeated. Once the part is finished, it is surrounded and supported by loose powder, which is then shaken loose from the finished part. This can be done in a variety of materials to suit the customer's specific needs. Finished models can be sanded to produce a superior surface finish and painted or electroplated to enhance appearance. Secondary operations like milling and tapping are also possible.

You may be aware of SLA (stereolithographic) or SLS (selective laser sintering) processes but have been put off in the past due to the cost; the service we offer is a much less expensive option.

What can be 3D printed?


Basically anything that can be modelled can be printed, we can accept any models in a variety of formats but we would prefer step, stl or vrml files. Should you have 2D data (dwg or dxf) or even "fag packet sketches" we can create 3D models for you, suitable for printing and other associated activities. We can print single models up to 8"x10"x8" (203mm x 254mm x 203mm) however parts can be joined together to produce larger parts.

Binder is printed onto the powder,

like ink, to form a cross section

of the finished part.

What are the advantages of 3D printing?


Well that is really like asking how long is a piece of string? But the main advantages are speed and cost. Parts that would have cost thousands of pounds and taken weeks to produce using traditional methods can now be produced for hundreds of pounds in days or even hours. These can be used for concept modelling, presentation models, functional testing and visualisation. In addition, 3D printed models can be used as master patterns for investment casting and silicone rubber moulding. In some cases the printed parts can be used as a working parts. All of these can save time and money for your company.

Have we convinced you yet?


When we first looked at investing in a Z corp 3D printer one of the companies we worked with produces high end hi-fi equipment and we got a mock up of the front of a hi-fi system made for them. At first they were not impressed as the buttons did not protrude far enough to make them functional, however on closer inspection the problem was with their model and not the 3D printed parts. The next day they were going to get production tooling produced, so the prototypes saved them many thousands of pounds in tooling modification costs and saved at least five weeks in getting the product to market. Having already seen what the Z corp printers could produce that was enough to convince us.
