Meet ... the Filameister

Expert at filament deposition

Overview

3D Printer capable of the FDM process. Design will be optimized for quality components and dynamically stiff structure to produce excellent quality prints. The design should look more professional and less like a hack job with clean layout of especially cables etc. The printer should be capable of a number of materials, from PLA to PC. The original design will be for one filament at a time. The build volume will be enclosed to prevent airflow, but will probably not include any insulation or heater.

Details

Note: this is a work-in-progress and I will try to keep this post current.

Build Volume

Shooting for around 200x200x200mm build volume

Structure

The structure will be aluminum t-slot frame with acrylic panels for shear stiffness. Additional aluminum and polycarbonate components may be used as brackets or supports as necessary. 

The axes layout will be an XY gantry (x moves front to back on two Y axis rails) with the bed mounted to Z moving up and down under the gantry.

The linear bearings will be recirculating ball type linear bearing rails (not rods) for X, Y, and Z axis.

Hotend

E3D-V6-1.75mm Universal for Bowden with 30W heater and PT100 sensor

Extruder

Bondtech BMG 1.75mm Bowden

Controls

Looking hard at the Duet3D-Wifi running RepRapFirmware or possible g2core-edge. motors, bed, hotend will be 24V.

Belts

Gates GT3 2mm pitch belts and pulleys

Motors

Sized as appropriate. Right now, its looking like NEMA17 0.9deg stepper for X axis, the rest are TBD after mass and speed calcs

Bed

The bed will be heated. Print surface will likely be removable glass plate. There may be an aluminum heat spreader under the glass.
