SAMG proposal on feasibility study for 3D printer project - Peter Gheude 9-9-2017 What is RAMPS ? The Replication Rapid-Prototyper Project (RepRap) is an open source hobbyist “do it yourself” low cost 3D printer project. RepRap Arduino Mega Pololu Shield, or RAMPS for short is a motor controller shield for the Arduino Mega2560. See: http://reprap.org/wiki/RAMPS_1.2 Basic components and considerations when building a 3D Printer. ACME Leadscrews Rods, Belts and Shafts Linear Guides Hot Ends Extruders Heat Beds Filaments Build Volume X, Y and Z Motor drivers Motor Types Cubic Frames Dual Z Axis A key component kit for a 220x220 version can be obtained from various suppliers such as; Note there are latter choices with the RAMPS and Arduino combined. https://www.aliexpress.com/item/3D-Printer-Kit-set-Ramps-1-4-board-12864-LCD-Screen-MK2B- Heatbed-A4988-motor- driver/32769335220.html?smToken=072e46394ee3431f8ce4b89a35422f9c&smSign=1QzGOzizwG p9H%2F%2B04WI3NA%3D%3D Example of an incomplete basic kit for around $50 Example of ACME Lead Screw There are numerous providers of Kit Projects with a multitude of designs and electronic controllers. Cartesian Core xy Delta Laser etch and cutters Printer Types FDM - Fused Deposition Modeling MJ - Material Jetting - Wax Casting DLP - Digital Light Processing SLA - Stereolithography SLS - Selective Laser Sintering SLM - Selective Laser Melting BJ - Binder Jetting LOM - Laminated Object Manufacturing EBM - Electron Beam Melting There is much room for improvement including; Stability of structure Precision Size too small ? Easy of constructing an enclosure to maintain temperature Cost of 3D printer When adding Laser Diode the XY area too small H-BotXY (CoreXY) vs Cartesian vs Delta Other reasons Questions for meeting Is there a group 3D printer project here? Is it worthwhile that members participate in a feasibility study to build an FDM 3d Printer? The committee and volunteers could shop around to determine if the components can be bulk purchased at an affordable price? A fun project and in keeping with the groups goals. The cost would be a key issues. How much? Large intelligent community. What do you think?
