Overview
Expand our current collection of 3d printers by adding two Prusa XL’s (provided by Asmbly) and two Prusa MK3S’s(donated to Asmbly). Doing so would allow us to create an intro to 3d printing class with a curated experience for new users, allowing them to get their feet wet before moving onto more nuanced printing with other printer manufacturers.
Goals
- To increase the use of the 3d printing area by reducing complexity of devices in service.
- To instill confidence in the end user by giving them instructions that will help them achieve a near 100% success rate with their projects the 1st time around.
Specifications
A little while ago I was speaking to Travis about the 3D printing area and 3d printing in general and something that we could agree on was the hodge podge nature of our current printing setup in the 3d lab. While the majority of the printers are in service with only one truly out of service the end user has to remember the particulars of each printer which isn’t great for people looking to get started quickly. Therefore I propose that we switch to a fleet of printers that are all the same and “it just works” premise so that the end user can start printing what they want, be successful and then explore/ go down the rabbit hole of advanced printing.
How to achieve this
My proposal is to refit the lab with three Prusa Printers. Recently Prusa announced the PrusaXL which is a CoreXY printer with a 14.17’’×14.17’’×14.17’’ print volume, option for multiple tool heads, a segmented heated bed and a host of other features that would make printing a frustration free experience. Many more of the enhanced print features can be found here Prusa XL but I’d like to highlight this part of their webpage
“Load Cell-based system for fully automatic first layer calibration. No manual calibration, no Live Z adjustments. The XL achieves a perfect first layer across the entire surface every time you start a print.”.
This is the core of getting people up to speed quickly after instruction; they also make repairs far less frequent than our current collection of printers. With this printer we can instruct new users using either PrusaSlic3r or SuperSlic3r (SuperSlic3r is a better version of Prusa’s version as SS takes some of the best features of Simplify3d and PrusaSlic3r).
“But what about our current printers?!” Yea that is the question du jour, they work but are not uniform, there is a tendency of people using them improperly which leads to errors and with errors it becomes an unpleasant experience to the new end user. The Polyprinter and Qidi X-Max should definitely stay around as they can be tasked to specific materials/nozzles. Lulzbot, Robo, CR-10 (and CR-20) could become a part of a more advanced/in depth 3d printing class that goes over maintenance, first layer calibration, firmware writing, etc
Costs
Three PrusaXL with 2 tool heads will cost 7,497. Since it will ship from Prague I don’t know how much is actually needed in shipping/VAT costs or how our status as a 501c3 will impact that price if at all(website said we get a 5% discount). Also since it’s still preorder there isn’t a price listed on the baffle attachment to protect the print area from drafts but with X-max and Poly, those two could be ABS only)
Shouldn’t be much of a lift as we can build a new medium to large enclosure to hold more printers. See the addendum here.
Needed Action
- Find a location for the new printers while minimizing the displacement of the current printers in the lab
- The space in the lab is limited as is so some displacement is gonna happen. But a “U” shape maybe the best course for additional printers.
- Possibly building a new enclosure for the printers.
- Sort through our current items and decide what needs to stay and what needs to go as well as general organization/labeling of parts and other consumables.
Volunteer Statement
- With this initiative I pledge to assist with the following:
- Writing curriculum for the use of prusa slicer and basic workflow of the Prusa printers
- Instruction of said curriculum to new users or to others that wish to teach a very basic class as needed
- Assembly of the printers and work surfaces/enclosures.
- Sort and organization of the current parts and consumables in the lab.
- Work with other members to secure a Grant for 2 additional Prusa MK3S’s
- Work with contacts to possibly get a filament sponsorship or a discounted rate on filament for use with these machines.
