So I’ve been exploring the fabulous word of additive manufacturing for a few months now with my company’s 3D printer - a Prusa Mk4 - that we employees are welcome to use for our own personal use when it’s not busy printing tooling for work of course.
I’ve gotten really good at squeezing the most performance out of that thing: some of the functional parts I made with it at scales that are pushing the boundaries of what regular PLA out of a 0.4-mm nozzle can be coaxed into becoming, I’m properly proud of.
And I’m having a lot of fun finding ways to overcome the limitations of FDM. I don’t really want a more precise printer: half the fun is witnessing a part that shouldn’t exist come out of a printer that doesn’t really have any right to be this good. Pushing the envelope… It’s the spirit of hacking in the world of 3D printing and I love it!
But now I’m wanting a printer of my own. The company’s printer is fine and all but when it’s doing work-related things, I can’t use it. And I have to wait to go back to work the next day to print something I modeled the evening before.
So I’m on the market for a good fast FDM printer that can print prints with different filaments at the same time, because I’d like to experiment with stretchy materials but keep using rigid and cheap materials for the supports, and also to play with colors. And I think I want a core XY printer because I’ve run into problems with big heavy prints with the company’s bed slinger.
And finally, something that’s really important for me: I want something as open source as possible that doesn’t phone home, and ideally not made in China.
Money is not tight. The kids are out of the house and I have a well-paid job. I set my budget to 5k - dollars or euros.
So with those requirements in mind, from what I read, the best option for me is to stick with Prusa: it’s more expensive for what it does but it’s not sketchy Chinese spyware. Also, I know the brand already and I’ve been nothing but happy with it so far.
And in the Prusa line, I’m tempted by the XL with an the bells and whistles - namely 5 heads and an enclosure.
But here’s the thing: I hear this machine has problems. Is it true? Would you have a better suggestion? Possibly another brand that I should consider?
People are going to suggest Bambu printers, but if avoiding Chinese spyware is one of your criteria I would advise avoiding anything and everything by Bambu, regardless of how shiny it is.
Look into the Qidi I-Fast, which is a dual extruder machine, i.e. with two separate toolheads. Its multi material capability is superior to the Bambus in that regard, working more similarly to your work’s Prusa, albeit only supporting two materials at a time. Qidi is also Chinese but I have owned two of their printers so far (an OG X-Plus, and a current Gen 3 X-Max) and I can find no evidence that they engage in any spying or other misbehavior. The I-Fast is $1800 USD right now which is well within your budget.
Honestly, for $5000 you can buy a lot of printer, or multiple printers. Plan B I think would be to just get the Prusa XL as you have already suggested, which is a sound strategy. Me, if I ever manage to accumulate enough Prusameters to do so, I am 100% cashing them in for a Prusa XL.
Despite claims to the contrary (largely by their manufacturers and fanboys, myself sometimes included) there is no such thing as any 3D printer from any brand using any technology that is truly plug-and-play, and 100% problem free. The damn things are inherently full of moving parts, tiny clearances, consumables, and wear items which will all at some point or another require your attention either via tinkering, tuning, or occasional parts replacement.
Yes I kind of wrote off Bambu for those reasons - not least of which because Bambu was founded by former DJI employees, which in and of itself is alarming if you care about privacy.
I would like one industrial replicator, please.
