3D printers have bloomed in the market in recent years. They are expensive to make and maintain. Large models only allow for prints up to 1-2 cubic feet. Our purpose was to create an affordable large scale 3D printer to appeal to “Maker” community hobbyists and do-it-yourself enthusiasts. DreamBIG has designed and fabricated a prototype that does not require heavy specialized machining equipment or costly custom parts. The gantry our team created can safely support and control up to a 500 pound extruder equipment and spans a printable volume of 8 x 8 x 6 feet. This design provides the foundation to enable the electrical controls and extruder attachment of our partner teams. We created a simple, robust, and reproducible foundation at a fraction of the cost of 3D printers available today.
