Non-Planar 3D printing
First off, I LOVE my MK3, except for nozzle replacements (normal wear) I haven't had any issues with my Prusa.
After watching videos on non-planar 3D printing I see where it could go.
Does Prusa have any plans on non-planar 3D FDM printers?
RE: Non-Planar 3D printing
Considering that non-planar printing is limited by the depth of the nozzle, it's not practical for much more than a shallow demonstration print using today's consumer-grade FFF technologies.

Here you can see a 5-axis printer, but... the great problem is a well-functioning and affordable slicer software:

Sounds like a redesign with a longer nozzle is needed 🙂

RE: Non-Planar 3D printing
A great review and share by Teaching Tech on YouTube shared the dramatic use of this technology. This would be a great mod or addition to the MK3; I am looking forward to finding more information or creating a means to make this possible for the community.
Here is a link to the video found today; enjoy 🙂
Great thanks to those that have shared! Amazing how much thought and work that has already gone into this to make it reality!
RE: Non-Planar 3D printing
Do you not understand the technology? Non-planar printing requires a nozzle that can be oriented at every angle within a 360x360x360 degree world sphere. The MK3 can not do this.

The closest current consumer technology that I can think of that would have a chance of angling the print-head even a little bit would be a delta printer. But that would still be limited angles, and a designer would still have to worry about the head hitting a tall feature next to the one that is currently getting printed on. Considering Prusa doesn't have a delta printer line, I wouldn't expect anything like this from Jo nor his team.

RE: Non-Planar 3D printing
Yeah - a world coordinate system escapes most folk. Best example I can come up with is to ask them to hold a ball with the left hand using two fingers, now touch every spot on the ball with one of the fingers of the right hand; but you can't turn the ball to reach any of those spots.
ps: the final phase is asking why they didn't touch the spots under the two fingers holding the ball.

I understand, I simply must pinpoint my focus on the area that the conscious observer seeks.
It is best to understand how the 2D world creates the 3D world or vice versa. How light is reflected into various dimension(s). A whole new dimension presents a whole new perspective to create from.
Once this is able to be envisioned, then we are able to build an appropriate coordinate system for a 3D printer.. after learning more about various expertise's in how current systems work for adaptation.
Anything is possible, although we may need to do a redesign for the MK3. It is similar to looking from a 5D imagination into a 3rd dimension or a 4th into a 5th. The circle or sphere is most definitely the most complex object ever imagined. I remember when we use to think our world was 'flat' 😋
RE: Non-Planar 3D printing
Thomas and Stefan did a good rundown on the topic in a recent Meltzone Podcast episode. Non-planar printing is currently only a demonstration that can only be used on very specifically-prepared parts. It's a gimmick. It's not going to show up in consumer-grade products anytime soon. Think of it as a hint of future possibilities, much like cold fusion or faster-than-light travel. Neat, but not something a company should go diverting significant efforts towards developing unless that's their main business.

We already know how to do this, CNC machines are available that can mill parts in full 3D (with constraints) and can easily be adapted to non-linear FDM build. But few of us have the money to own one of those machines.
It is sort of like asking for a ride to the moon for the cost of bus fare to downtown.
ps: Here's an example of a machine that can manipulate a part with enough degrees of freedom it could be adapted to FDM non-linear printing (more or less).

RE: Non-Planar 3D printing
There are other technologies that hold much more promise for the consumer to eventually be able to build most anything at home with increasing resolution. Much like electronic photo printing, where once we had dot matrix and dithering, we now have 2400 dpi on our desk tops (which still dither, by the way).
But focused laser curing of polymeric substrates, it's already in the lab, and will soon be something we can afford to buy; and it will be 100 times better than any FDM technology.

@tim-m30
Yes, I understand what a monumental remodeling it would take. I posted my question because I am not the only person who has to believe it's the next step for FDM technology. The point of forums is to elicit a conversation, that conversation might spark an idea to make it a reality. I have neither the time or knowledge to figure out how to make it a reality. What I do have is a desire and money to pay for a finished product, just like when I bought my MK3 kit.
RE: Non-Planar 3D printing
Amazing ... "FDM can't do this" is pretty clear English. And there isn't a way to make FDM do it in any economical/commercial sense. But dream on. It'll be a long wait to place an order, so get a few hundred good books, or a few thousand if you are a fast reader.
While you are at it, wish me a $500 Ferrari 812 GTS, we know they can make them cheaper than a few million and it's just a matter for the technology to catch up.

I guess I must have dreamt the videos of FDM printers printing non planar....oh wait, no I didn't.
There is a concept called economy of scale, It's an economic term, basically the more you make of a product the cheaper it can become.
It's not easy, or readily accessible, but it has been done so it is possible.

[...] I guess I must have dreamt the videos of FDM printers printing non planar....oh wait, no I didn't.
Have you seen one showing a print any deeper than a belt buckle? Yes, there are demonstrations of the basic technique, but that's it. It may be a hint of things to come, or it may just be yet-another technological dead-end.
There is a concept called economy of scale, It's an economic term, basically the more you make of a product the cheaper it can become.
But you do have to make a viable product to start with. That's the challenge here. Unless you want to print belt buckles exclusively, this technique isn't practical with today's consumer-grade FFF technologies.

For belt buckles. Until you can show a Benchy printed using this technique using off-the-shelf consumer grade FFF technology, it's really just a gimmick. Yes, it would be really neat-o to have something like this available, but it won't be done with the 3D printers we have today. All of the breathless posts pointing to yet-another shallow print are just repeating the same trick. And it's not a new trick.

RE: Non-Planar 3D printing
There is concept of 5 DOF printer already, check this thread: https://www.reddit.com/r/3Dprinting/comments/bs7dml/first_tests_using_our_5_axis_printer_slicing_done/
It's really interesting and can bring many possibilities for repairing and reconstructing in place. Providing issue with surface detection gets sorted out.
RE: Non-Planar 3D printing
And another interesting approach to this: https://www.reddit.com/r/3Dprinting/comments/5obi15/6_axis_3d_printer/ this time nozzle is vertical and print surface moves.
RE: Non-Planar 3D printing
This FDM technology is at least possible: it allows the ability to make arbitrary changes in layer height. But print times grow exponentially.

And Chris: as soon as you show me a print of this part made using the non-linear process to print the wings perpendicular to the surface I'll be sold it will one day be possible for consumers to own such a thing:
