CAD / 3D Printing: convert drawing for metal-work to plastic 3D printing
Budget $30-250 USD
I would like to create a pilot – a test – to see if it’s possible to convert a 3D drawing for metal-works into a 3D drawing tailored for 3D printing. There are some specific properties and limitations is 3D printing which needs to be considered compared to manufacturing in metal.
For the pilot, I have chosen a part called “BALJA”. It is pretty large and in metal, it’s made up of several pieces which is put together. For 3D printing, all parts are not needed to be printed separately, but everything as a unit.
To make a be successful drawing for 3D printing, the attached PDF ([login to view URL]) must be fully understood, the composition and how it will look assembled in metal. To your support, there are also files for SOLIDWORKS which is related.
Once the metal version is understood, the creative work will start and here comes the properties and limitations of 3D printing:
• The 3D printer can print objects 290 x 290 x 390 (height) in mm which means this PDF drawing needs to be split up into parts which can be fit within this volume.
• Each part, will be glued together to other parts. I will print with ASA and to assemble parts, Acetone is used to “weld” parts together. Where there is two parts which needs to be joint together, then the parts need to lock to each other. There are different ways of doing this and I will leave it up to you how you design this.
• The drawing is currently for metal work and is made out of metal sheets which is quite thin. This does not work for 3D printing, so the sheets needs to have a thickness of 6 mm. Where you have two parts joining together, you can increase the thickness to double to allow for a solid joint with the two parts.
From this PDF, I expect there to be around 12-15 drawings for each part of the 308030 model.
A suggestion for you is that when you start make the first drawing, send it across to me for an early validation. The joints between parts may be tricky and if nothing else, can carry some questions.
• I expect to receive a number of STL files where each STL file is one part which makes up of the full “BALJA” part (308030).
• Each file needs to adhere to the limitations of 3D printing I explained above.
• I expect also to receive a HTML file (or similar) where I can view all parts are joint together. I will use this as a first quality assurance that all looks good for printing.
As this is only one part and given a successful outcome, there is a good chance for repeat hire.
