To assist the technical evolution of these systems, this study provided the details of an invention for a low-cost, easily replicable open-source grinding machine for compression screw manufacturing. The system itself can be largely fabricated using FPF/FGF following the self-replicating rapid prototyper (RepRap) methodology. This grinding machine can be made from a cordless cut-off grinder and < $155 in parts. The new invention is demonstrated to be able to cut custom screws with variable (i) channel depths, (ii) screw diameters, (iii) screw lengths, (iv) pitches, (v) abrasive disk thicknesses, (vi) handedness of the screws, (vii) and materials (three types of steel tested: 1045 steel, 1144 steel, and 416 stainless steel). The results show that the device is more than capable of replicating commercial screws as well as providing makers with much greater flexibility to make custom screws. This invention enables the DRAM toolchain to become even more self-sufficient, which assists the goals of the circular economy.\n\n{{Pearce publications notice}}\n\n* BOM, CAD, Full source code: https://osf.io/ev6ta/\n\n{{Video\n| video = 6P7IGj5Wa7k\n| title = Using the OS Grinding Machine\n}}\n\n== How to use it ==\n\n* Nice review of screw-based 3DP<ref>https://link.springer.com/article/10.1007/s00170-021-07365-z<ref>* [[Making the Tools to Do-It-Together: Open-source Compression Screw Manufacturing Case Study]]\n\n{{MOST-recycle}}\n\n== News ==\n\n# [https://3dprintingindustry.com/news/michigan-tech-researchers-invent-open-source-grinding-machine-for-compression-screw-3d-printing-173325/ Michigan Tech researchers invent open-source grinding machine for compression screw 3D printing] 3D Printing Industry 72k [https://svmakers.org/michigan-tech-researchers-invent-open-source-grinding-machine-for-compression-screw-3d-printing/?doing_wp_cron=1595162688.8847200870513916015625 SVMakers]\n# [https://hackaday.com/2020/07/09/open-source-grinder-makes-compression-screws-for-plastic-extruders-easy/ Open-Source Grinder Makes Compression Screws For Plastic Extruders Easy] Hackaday 9.8k, [https://www.thetechstreetnow.com/tech/open-source-grinder-lets-you-make-your-own-custom-compression-screws-for-3d-printer-extruders/11194264494728433696/11194264494728433696/ Tech Street Now]\n# [https://3dprint.com/270286/open-source-grinding-machine-cuts-cost-of-pellet-3d-printing/ Open Source Grinding Machine Cuts Cost of Pellet 3D Printing ] 3D Print 75.7k, [https://www.3dprintingtoday.com/open-source-grinding-machine-cuts-cost-of-pellet-3d-printing-2/ 3D Printing Today]\n# [https://www.morgen-filament.de/3d-printing-en/latest-news-of-3d-printing/ Latest News of 3D Printing] Morgen Filament\n# [https://medium.com/@top3dshop_com/grinding-machine-from-professor-pearce-8d5afb4c20e3 Grinding Machine from Professor Pearce ] Medium 79\n\n== References ==\n\n<references />\n\n{{Page data\n| keywords = grinding machine, open-source appropriate technology, compression screw, grinding, cylindrical grinding machine, material extrusion, angle grinder, Circular economy, Distributed recycling, Polymer recycling, Sustainable development, distributed manufacturing, life cycle analysis, recyclebot, 3d printing, Open source hardware, Open hardware, RepRap, Recycling, Polymers, Plastic, Recyclebot, Waste plastic, Composites, Polymer composites, Extruder, Upcycle, Materials science, additive manufacturing, open-source\n| sdg = SDG09 Industry innovation and infrastructure\n| organizations = MOST, MTU\n| description = Discover a low-cost, open-source grinding machine designed for compression screw manufacturing, enhancing DIY 3D printing and supporting sustainable practices.\n}}\n\n[[Category:Polymer recycling]]\n[[Category:MOST completed projects and publications]]\n[[Category:3D printing]]\n[[Category:Recycling]]\n[[Category:Rural community development]]\n[[Category:Polymers]]\n[[Category:Plastic]]\n[[Category:Plastic bottles]]\n[[Category:Sustainable development]]\n[[Category:Distributed manufacturing]]\n[[Category:Life cycle analysis]]\n[[Category:Recyclebot]]\n[[Category:3d printing]]\n[[Category:Open source hardware]]\n[[Category:Open hardware]]\n[[Category:Materials science]]"}
