One of the makerspace areas upgraded during the pandemic was 3D printing. There’s been several printer upgrades and we even added a new liquid resin printer to the makerspace.

The most significant change has been to our delta 3D printer, upgrading our Rostock Max from v3 to v3.2. That included 3 major upgrades; a new printer controller board, upgrading the stepper motors, and a new hot end.

The controller board change went from an Arduino-based RAMBo v1.3, an 8 bit control board, to a newer 32 bit Duet WiFi board for the printer ‘brain’. The RAMBo board is certainly a good one, we’ll probably use it to build another 3D printer, but the Duet has major improvements in both usability and speed. The Duet is also WiFi remote controlled and since the control board is located internally, the former LCD panel and SD card was removal. We recently bought a PanelDue, so there will be a new touch screen control available soon when we make that upgrade next.

We also changed the 1.5 degree to .9 degree stepper motors. Combined with the Duet control board this reduces the printer noise level dramatically and improves printer quality/speed with the micro-stepping addition. A new hot end assembly also improves the bed leveling sensitivity and heating capability. Bed leveling and the ability to print higher temp materials are a nice improvement for this machine!

There’s been other improvements in makerspace 3D printers, including the Printrbot Metal Simple & an older now modified XYZ printer. We’re in process of setting up a workspace for a MoonRay S100 SLA/DLP 3D printer & will write up more about that in a future post. Come to one of our 3DPO (3D Printer Owner’s) meetups, the next one is 12/30 at 6:30 pm. Or stop by Castlemakers to learn more!
