This is a Mostly Metal, Leadscrew driven printer with a reasonably sized build volume.T slotted extrusion frame is all CNC machined and Xaxis carriage is machined to integrate linear bearings and leadscrew nuts.Printer is good for printing moldings and other projects. It isn't the fastest printer by any measure at all but it is extremely reliable because of the metal frame and leadscrews. Next iteration will probably include belt driven X&Y axes for a large speed increase and will reform the printer frame size around the build platforms.Actual Build Volume: X: 375mm Y: 260mm Z: 280mm Volume: 27300cm^3Linear Motion: X&YAxes: 8mm dia rod with cheap linear bearings 8mm dia leadscrew with 2mm pitch and 4startsZAxes: 8mm dia rod with cheap linear bearings 8mm dia leadscrew with 2mm pitch and 1startBOM:https://docs.google.com/spreadsheets/d/1Gwe15uqKOj_OOHFW0r1COhH6iVW_NGl7IuCsY7lVwB8/edit?usp=sharing
