Please go to Category: T-Slot for the full list. Thank you.

"T-Slot" is a type of Beam made from extruded aluminum.

This page is dedicated to the creation of a 3D Replicator with a frame based on T-slotted framing. Here is an excellent source of these materials: http://8020.net/T-Slot-1.asp

We feel that the desire to self replicate has been holding back the RepRap device from gaining wider acceptance and also attaining higher performance levels coupled with greater versatility. Ideally a T-Slot Replicator will be multi-tool enabled with support for FDM, Shape Deposition Manufacturing, CNC_Mill Spindles, Pick and Place and possibly other tools like lasers and Laser Cutters. We also would like to see more versatile and off the shelf solutions for the electronics as few are willing or capable of creating their own boards. Lastly, the software needs to be more plug and play so that less time is spent installing, configuring and tweaking. See also Development Pathway

Development Pathway

This page will eventually fork into a tree of different webpages. That will include SamBot, HydraBot, My Extruded Aluminum RepStrap, My Extruded Aluminum Laser Cutter, and so on. But right now, all the action is on this webpage.


kinds of T-slot

VSlot: Metric Extrusion with built in Linear Rails

fischertechnik aluminum beams look similar to MakerBeam. See FTIStrap.

fischertechnik: you can get extruded aluminum versions of some fischertechnik parts

80/20 beams: typically used for machines larger than a refrigerator

MakerBeam: typically used for small desktop models
