Scalable Delta Printer

The aim of this design was to create a scalable 3d printing platform which uses what I consider to be the best available components. My requirements are:

• Scalable from large (XXL 400mm+ XY, 300mm+Z) size to monstrous (XXXL 650mm+XY, 1100mm+Z)

• Be 'enclosable'

• Have a choice of removable bed surfaces

• Quick change tooling

• Have a simple assembly, manageable by one person alone

• Be capable of creating very large, accurately sized, high strength parts in reasonable times

• Be able to print common materials such as PLA, PETG, ASA, ABS

• Have a low count of overall parts

• Use 'best of breed' parts where possible

• Design printed parts so that they can be produced on a 'normal' sized 3D printer

• Be as 'open source' as possible

I think for the most part I've managed to achieve the above, and have created a design which stands up to heavy use without breaking a sweat. Between the two machines I've created with this design, I've performed around 2000 hours printing so far, and they are outperforming my consumer printers in most areas on every print.

I wasn't able to upload Excel sheets here so the BOM is available here: [https://1drv.ms/f/s!AiA0W_qYRT2Nhdtp-tNuQ4XVGAJnPQ](https://1drv.ms/f/s!AiA0W_qYRT2Nhdtp-tNuQ4XVGAJnPQ) which also documents suggested print settings.

Building these machines is a lot of fun and results in a very useful and reliable tool - and you usually get to win the 'who's printer is bigger?' conversation at your maker space!
