D3D Mega v23.05 Module Breakdown

Module Breakdown with explanations of how each module fits into the OSE Specifications. Specific attention given to the specifications of Modular, Low-Cost, Simplicity, DIY, High Performance, Industrial Efficiency, Lifetime Design, Scalability, and others more closely related to product vs civilization/community design.

[edit]

Universal Frame

The Universal Frame module is a scalable and low-cost foundation for the 3D printer. Its open source, simple design allows for distributed manufacturing using common off the shelf components combined with 3D printed parts. See Frame Construction Set.

Interfaces

• The top corners interface with the ends of the Y axes using nuts and screws.
• The Z axes are affixed to the frame via movable bases that are secured in place with fasteners screwed into plastic.

Universal Axis

The Universal Axis is a belt-driven precision motion system that can be used in numerous places throughout OSE's product ecology. The module can be scaled intensively and extensively by either moving up to larger axis/belt sizes or by doubling up axes together. See Universal Axis.

Interfaces

• The idler, motor side, and carriage all have some variation of the 30mm square bolt pattern that is seen best on the carriage. This allows for the attachment of almost anything with nuts and screws.
• The precision rods can have springs added around them to aid in counteracting heated bed weight.
• The precision rods can have rings added to suspend a fireproof fabric covering over the heated chamber.
• The stepper motor is connected to the Universal Controller via a XH2.54 4pin to XH2.0 6pin connector cable.

Universal Gearless Extruder

The Universal Gearless Extruder is a 3mm plastic filament extruder designed to have the shortest possible distance between drive and melt zone, an exposed and easy to maintain filament path, and excellent handling of even the most pliable of rubber filaments. All of this makes the extruder robust, high performance, and quick to troubleshoot. See Universal Gearless Extruder.

Interfaces

• The extruder assembly is attached to a universal axis carriage using one M6 screw and nut.
• The fans, height sensor, stepper motor, thermistor, and heater cartridge are all connected to the Universal Controller with various wires.

Fast Heated Bed

The Fast Heated Bed is powered by high temperature halogen lamps running on 120V AC. The heating capability of the bed can be scaled by increasing or decreasing the number of halogen lights. The bed surface is made from commonly available steel plate. See Fast Heated Bed.

Interfaces

• Affixed to the bed rods with wires run through holes in the bottom of the bed assembly
• Connected to 120V AC via the solid state relay in the Universal Controller

Universal Controller

The Universal Controller is a LCD-screen equipped controller that is capable of controlling 3D printers, CNC machines, welders, filament makers, automated machines, or any other applications where a microcontroller runs different actuators, sensors, or power elements. See Universal Controller.

Interfaces

• Connects via wire to all stepper motors, heater elements, and sensors on the 3D Printer
• Connects to frame using movable connectors on the frame's angle iron

Heated Chamber

The heated chamber is a simple steel shell with high temperature insulation inside. See High Temperature Heated Enclosure.

Interfaces

• The bed rods slip through fireproof baffle bags attached to the edges of the chamber. This allows Z motion while reducing movement of air inside the chamber.
• The fireproof fabric top covering is affixed to the bottom of the Universal Gearless Extruder/X carriage using magnets.
