FTIStrap

This page describes the "FTIStrap", a RepStrap which is almost completely built from FischerTechnik parts.

(please note: because of relatively strict time limits, I plan to document the FTIStrap piece by piece finishing around midth of november)

Stepper motors are used as actuators, the interior of a hot-melt gun forms the extruder and a (removable) glass plate acts as the base to print on. A FischerTechnik "Robo Interface" together with an extension module (both running in "online mode") controls the steppers and scans the end stops - they can be connected to an IBM-compatible PC running Windows or Linux or a Apple Macintosh running MacOS X through a serial interface.

Its main "advantages" are

- the FTIStrap almost completely consists of FischerTechnik parts - stepper motors are 

(which can easily be ordered online) - all other parts may be also bought online or found in various shops in your neighbourhood
- no special tools are required to build the FTIStrap - although a hacksaw is recommended to cut the balsa wood
