D3D Pro 3D Printer

The D3D Pro 3D Printer is an open source additive manufacturing machine developed by the contributors of Open Source Ecology. D3D stands for Distributed 3D, as the D3D project is meant to be built primarily from low-cost, locally available materials. The printer is part of OSE's Global Village Construction Set.

The main benefits of using this machine are its open hardware license, its low cost, high throughput performance, and its modular and scalable design.

• Large build area (300mmx300mm for v23.12)
• Uses open source electronics, software, and off the shelf motion components
• Can be converted to other uses, such as the Belt-Driven Open Source Circuit Mill Using Low-Cost 3-D Printer Components
• Modular design that enables intensive and extensive scalability. Add extra axes, more extruders, more beds, or swap out for larger components in high force applications. Scale to any size required for your project.

• Universal Frame: A cube-shaped frame made of 1/2" rebar (12.7mm) and 3D printed fittings.
• Universal Axis: A scalable, belt-driven motion axis system based on 8mm smooth rods.
• Universal Controller: A controller system that can operate almost any actuator, sensor, or power element that requires less than a 100kHz control signal. Uses RAMPS 1.4/Arduino Mega, a Raspberry Pi, GFCI protected power supply, and solid state relays.
• Fast Heated Bed: A rapid heating print surface powered by halogen lamps.
• Universal Gearless Extruder: A high temperature, high-throughput filament extruder.

• Universal Frame: constructed from 1/2" (12.7mm) diameter rebar stakes in place of the previous versions' 1/8"x1.5" (3.2mm x 38.1mm) angle iron profiles. 3D printed corner connectors were updated to accommodate the new space frame members.
• Universal Axis: strengthened connection joints for X & Y axis interface and redesigned the Z axis carriage to increase the stability of the fast heated bed.
• Universal Controller: added a 3D printable electronics enclosure and upgraded to Klipper 3D printer firmware from the original Marlin firmware.
• Fast Heated Bed: increased the size to 12"x12" (305mm) including additional halogen light bulbs for more rapid and even heat.
• Universal Gearless Extruder: added a high temperature ceramic heater cartridge and thermistor for compatibility with engineering polymers.
• Project documentation is generated using the Distributed OSHW Framework (DOF) legacy software, a model based systems engineering tool being developed to make hardware as modular, shareable, 'forkable', and reusable as open source software.

• The Z axis and electronics are already oriented to accept a high temperature heated chamber upgrade. The heated bed and the end of the extruder would be the only components inside of the high temperature chamber.
• Move from the OSE Universal Controller to the Open Source Framework for a Broadly Expandable and Reconfigurable Data Acquisition and Automation Device (BREAD) system for compatibility with other Appropedia projects, and to allow modular expandability of machine capabilities in the future.
• Use the Open-Source Grinding Machine for Compression Screw Manufacturing to upgrade the extruder to a pellet/regrind-based system.
• Further iterate on the Universal Frame design to increase rigidity using steel cable and turnbuckles to keep 3D printed components in compression with the rebar frame members.
• Redesign the interior of the Fast Heated Bed to include more halogen lights for higher temperature materials and more consistent and even heat across the build surface.
• Experiment with DIY mounted linear rails for increased rigidity at the center of the motion axes.
