Workshop aiming to build a number of 3D printers of the "delta robot" principle. We will try to stick to the original design as much as possible, but with metric/EU parts.
First steps
- Waiting to see how many participants will join, to know in which numbers to order components
- Querying wishes of participants in regards to build volume, other details, etc.
- Compiling a bill of materials and defining correct order to purchase them in
- Making sure all parts can be acquired in a timely fashion (and for a fair price)
- Printing a few of the parts, noting time required and quality/checking tolerances
- Scheduling a first pre-purchase planning meeting?
I've built my first printer with 1 meter aluminum extrusions, but a bit higher or lower is also possible. Say minimum ~75cm, max ~1m20 maybe ? It would be good to hear everyone's preference to get the order of that under way.
I've emailed Steve Graber, waiting to hear back from him on availability and cost of the CNC'ed parts...
Yesterday I have printed three parts -see pic-. The two upper parts each took 3,5 hours to print. The lower one took 3 hours. The two upper parts are supposed to fit together, but it is extremely tight, I need to test if it fits or that printing adjustments need to be made (or machining...) Also, whether the lower part fits my extrusion profile which is hard to test without disassembling my printer..
Then, as each printer needs six pcs of each pictured part (not 100% identical but close enough) this means 40 hours of printing(!) for just the base building blocks for 1 printer. This means careful planning is in order to avoid disappointments, and perhaps an early start on printing objects.
