Table Top Foam Cutter

thingiverse

This is a model of a tabletop foam cutter, printed in 4 parts with the base being 100x100x30mm and the available height of cutting wire being 90mm. A NiChrome wire or guitar string along with a DC power supply is required to operate it, with optimal electrical parameters found at 1-1.5V and 1.2-2A depending on the desired temperature setting. It is also possible to cut thin plastic parts such as PLA or HIPS sheet, in addition to paper. The back plate attaches using four 4mm self-tapping screws and a 7mm diameter compression spring ensures that the wire stays taut by maintaining a tight grip. A suggested spring rate of 2N/mm or higher is recommended for effective operation. A 6mm diameter bar fits into the slot on the underside of the foam cutter for wrapping the cutting wire around, with channels designed to route power cables along the outer edge and under the base. Rounding corners and fillets have been applied to prevent any potential issues related to interference fit components. To ensure a smooth print process, please review the model's finer details and features to guarantee successful printing on your machine. STEP files are provided for editing purposes, with other formats available upon request. ***If you find this model useful, consider supporting me by donating $0.99 via the link below: http://3dsha.re/product/table-top-foam-cutter/*** Thanks for choosing this tabletop foam cutter model! Instructions: All parts can be printed without supports except the arm which requires the 'support everywhere' option in Cura. The base is best printed with its top face against the build plate. Printed at 50mm/s and 20% infill, the base takes approximately 3 hrs 30 mins while the remaining parts take a total of 1 hr when printed at 100% infill. STL files are designed with dimension tolerances that work well on my printer, the DreamMaker Overlord (delta style), however STEP files have been provided for any necessary adjustments. As a general rule: internal diameters have been increased by 0.5mm.
