Abs needs an enclose vented to the outside, or really good ventilation. The ‘S’ in ABS stands for styrene, a fairly potent carcinogen and irritant. Do NOT print it in your living area as it off gasses while printing.
All other plastics you can print on the A1 will be safer.
I’ve printed plenty of different mid density tpu’s including random no name ones with generic profiles, using the Prusa Mini with its Bowden tube. It’s not always a no no.
It’s more about pressure than airflow. You just need negative pressure inside the chamber, so gas escapes into your chamber through the cracks, and out the vent.
I have my prusa connected to my WiFi, but it only serves up a Web page with limited control locally. You can only upload gcode, and start a print if the printer is ready to start. And it’s open source so I’d expect the community to have found any issues.
You should monitor it’s connections at the firewall and see if it’s trying to make ANY connections outside your network, no reason for it to try making any dns queries even.
You make a good point, and it’s really the reason I have and like Prusa printers. But I do look with some envy at the bang for the buck you get with Bambu
Isn’t there a group working on open source firmware? https://hackaday.com/2024/01/09/x1plus-open-source-bambu-lab-x1-firmware/
So if they are forced to remove something, it can be re-added
Have access to a quarter million dollar scanner from about 15 years ago. It still beats the pants off anything cheaper than 8 grand these days.
You pay for software that can handle millions of points, hardware that can stream a lot of points to the pc. A wide dynamic range to scan, nice matte white, chrome or dark black objects. And raw precision to cast and track very fine details
A $5 esp32 has more than enough computing power to run a vending machine, cameras and connectivity too. Would be cheaper than having to run all the analogue circuitry.
And a key tool in the Arab Spring uprisings
Twitter was the main tool in the Arab Spring revolutions. Whatever the Saudis paid to buy and destroy it was cheap for their goals.
I’m on the prusa mini as my first printer and it’s done spectacularly well, the few times I’ve needed a bigger bed I’ve been able to segment the parts and glue it back together.
One thing you haven’t mentioned is where your printer will be, mine is in my living space, so noise is a big concern. Placing down a foam pad and then a paving stone under the printer stops vibrations from echoing through the table it’s on. But the bambu printers though amazingly featured for the price, are noisy beasts.
There’s a datasheet available for your resin, as there is for any volatile product. Print that for your boss and show him the health risks, mostly cancer that he’s opening himself up to liability for.
They killed off other profitable divisions already, because the Csuite doesn’t understand it.
Next version will make the current generation cease working, even though there’s nothing wrong with the hardware
It takes lots of chops with an axe to break through
Prusa firmware is all still on github. They are using a few more machined or injection moulded parts where it makes sense for stiffness or things like the spool holder. Most of the printer and especially anything that might get revisions later is 3d printed
It does eat the pei sheets a bit, but that’s good to even out tiny marks and dings in the sheet. Like the previous poster said. It’s fine to do once in a while to refresh the surface, spring steel sheets are consumables anyway.
Scrub the bed with dish soap and a non stick scourer, dry it right away. Then print on that. Ipa only removes oils from your fingers, there’s other residue it won’t remove
Same for my whole city that is hilly and private garages are rare, people park on the roadside
How fast can you spin a cow on a spindle?
