A project log for TOME - Portable 3D Printer

Portable and self contained FDM 3D printer designed to be the ideal tool for field hospitals short on supplies and nomadic engineers alike.

One of the major enhancements to 3D printing that the TOME brings is portability, and when this is combined with several TOME printers interacting with one another we can print some fantastic things. Picture a field hospital with several TOMEs and a problem, they need to 3D print an arm brace but it's far too large for a single TOME. This model can be printed and split between all of the TOMEs at their disposal to quickly print the arm brace. Remote printing will also take a large leap by allowing teams to print collaborate on projects by printing parts to each others TOMEs for more rapid project development. Being able to collaborate over large distances seamlessly, deliver engineered products to those who need it remotely, and then receive real feedback with one system will enable us to develop technology faster and be able to help a wider audience. 

The overall block diagram for the TOME electrical schematic is underway, and I hope to be able to post the first version tomorrow for everyone to see. Dean Gouramanis is a good friend of ours and has been working on some powerful stepper motor drivers, Corey and I decided to incorporate them  into the TOME. Dean has also been working on a RepRap style Arduino MEGA shield that utilizes his stepper stack, unfortunately the TOME requires a different form factor in order to achieve the compact size; Therefore I'll be spinning a custom PCB set for the TOME.
