Building a large-format dual-extruder printer with V-slot aluminum frame and multi-material capabilities

Achieving the RepRap vision: the McWire printed a Mendel, which printed better Mendels, implementing true self-replication

A collaboration between electronics expertise and precision machining that created the J-Head, one of the most influential hot-end designs in RepRap history

Printing Mendel parts on the McWire and assembling a self-replicating printer capable of printing its own replacement components

Systematic troubleshooting solutions for extruder jams, flow issues, temperature problems, and mechanical alignment

Converting the McWire 3D printer into a CNC mill with a Dremel toolheadโthe beginning of workshop tool progression

Two years of extruder experimentation: from nichrome wire failures to reliable resistor-based hotends

Building a 3D printer from threaded rod, lumber, and determinationโthe first step in the RepRap self-replication journey
