3D printer

[Demon]

Some printers may seem very interesting at first glance.

And then you compare the specs with other printers:

Layer resolution: 0.1-0.3mm
Positioning Precision: 0.1-0.3mm

That makes me doubt the demos when I compare them to other printers. The orange elephant seems very good for such a weak spec.





The more I research, the more confused I become.

And then there's printers like these which seem just too awesome to be true:

Click on FEEDBACK.

Then click on the number to the right of the stars, starting with 1.

I just have to show this thing:

Not sure about doing any CNC work on an open-frame type machine. CNC throws dirt and debris everywhere. Those belts, motors, circuits, power supply, eeesh.

And then the guys doing laser work with their face right up to the printer without using any glasses?

That CNC precision doesn't look too fancy. Not sure I'd want to do my boards on that. And then there's the toxic dust from the PCB board.

We have a government agency in Quebec, loosely translated as Workplace Health and Safety Agency, they'd have a heart-attack just looking at this ad.

Wow, all the printers on AliExpress now look like ice-cream machines.

This looks promising as an upgrade:




Prusa is supposedly open-source (if I remember right), so in theory this should fit onto one of the made-in-china models. The Prusa original printers are triple the price.

If you can afford it, the original Prusa is the way to go ($699 in kit / $899 assembled). And then buy the dual ($199) or quad ($249) update above if you need more colours .

Wow, alot of work you have done!

Indeed the evolution of the 3D printers is great!

Thanks for the info you posted.
