Delta Bad Boy 3d printer

thingiverse

The provided text is a log of activities and decisions related to the construction of a custom 3D printer, specifically a CoreXY or delta style printer. The creator appears to be gathering and sharing various components and parts needed for the build, such as the following: 1. **Heatbed:** The creator has made a Heatbed plate in 4mm Aluminum (Alu) using a Waterjet cutter and has posted it online along with the SKP file, which users can edit or customize. 2. **Extruder:** The Extruder has been completed and includes Mounts for NEMA 23 stepper motors, among other parts. There are also mentions of considering using a 32-bit board for this part of the printer. 3. **Direct Extruder:** The creator is working on designing a direct extruder but hasn't shared it yet. 4. **Magnet Countersinks and Steel Ball bearings:** Components that are being considered or acquired for precise positioning in the machine's movements, like Hall endstops, have been noted. 5. **Bearing Types (Steel and IGUS):** The discussion covers alternatives for the X carriage, including IGUS plastic bearings for reduced weight compared to steel options, which would otherwise add considerable weight but are also more efficient and precise over time. 6. **Materials for Testing:** For test prints, cheap ABS filament has been suggested as an initial material due to its easy availability and low cost in various weights (e.g., 920g), priced around €14 per spool in Europe at the time of consideration. 7. **Nema23 Mount and Ramps Board Plate:** This involves detailed design considerations for mounts on the printer's X axis carriages, aiming for precise mechanical advantage from these moving parts. Additionally, mounting fans is suggested to be a rubber-mount process ensuring silence while operation is critical. 8. **Assembly Components (Aluminum Profile, Steel Rods):** A heat sink was chosen from E3D and profile materials (like those from MoDis) were referenced, along with sources for 16mm steel rods used in the moving parts of the machine. The user shares several sources from various suppliers on Ebay or from specific manufacturers for the components like magnet countersinks, bearings, heating systems (heated bed), or specific materials and tooling for construction like ABS filament. Throughout these activities, the emphasis has been on customizing as much as possible to suit performance and mechanical integrity.
