Is a lowered belt printer BETTER? 

Good walls then?

That's exactly what my first thought was

@@colinyoung3685 shortly followed by this

it's almost like it's half a cube.. 😋

That’s not the reason for this belt printer they wont to b able to print for example a one meter sword with this machine. If you want to print several things in a row this is not the way to go.

@@FT91-z5j out of curiosity, what would be your ideal solution if you were looking to print a large number of individual parts with minimal downtime?

@@WeAreChecking for me something like Thomas voron it’s Great to do that. But it’s a littlebit over engendered. For less down time the simplest way you can go is to push the prints off bed by the printer itself.

@@FT91-z5j that's not necessarily true. There could be a sequence that would allow part to print, then move the belt, continue printing.

@@dominick253 it would still have to be sliced diagonally or use non-planar 3D printing. Extruders still have a width to them, so you can’t just do sections.

You can feel the fury building up

Naomi be preparing all her cyborg ninja tech weapons & armour to pay Thomas a visit

Was low key hoping to find you in the comments! Also, it seems he has replied to 3D Printing Nerd's comment, but not yours...hmmm. maybe he is afraid XD. As an aside, I cant wait to get one of these belt printers in the future, I might be more inclined to mess around with cosplay :D.

Naomi ‘SexyCyborg’ Wu, do you think a PEI coated belt would help with his adhesion issues? He is using petg.

Is there some reason why it the belt can't be tilted the other way and the nozzle rotated 90 degrees to make a regular X-Y-Z machine with the belt being the Y? I would imagine that this was tried first, then the belt was turned 45 degrees for some practical reason. Would you mind sharing that reason and why having the nozzle at 90 degrees to the belt was a problem to solve?

Honestly, I don't need an infinite y axis. The 45° angle looks horrible too

I'll need to try Kiri:Moto with the CR-30 some day... Ideamaker, too!

@@MadeWithLayers Hmmm... What about a second extruder at the back--perpendicular to the belt--that lays down a thin, hot layer for the main extruder to lay the model on?

Once my CR-30 arrives, I'd really like to try Proper Printing's "Moving Portal Mod" to basically turn it into an ABP. 'Course, such a thing can't be commercialized til Makerbot's patent runs out in 2030, but a lights-out 3D printing work cell sure would be nice!

@@KeithOlson i was thinking the same thing

You should increase your top layer and bottom layer to 7 layers

But then it would be angled wrong for when its printing the rest of the part.

I was thinking the same thing as the video went on. Add 2 more stepper motors and a hinge and some shenanigans and you've got yourself a masterpiece.

@@Justkyrios Then we could also have a go at nonplanar printing. The only thing that remains is slicer support and proper bed materials for adhesion.

@@Tubaii25unfortunately all is missing is patents expiring... Adjustable angle printers -> patented i3 printers with conveyor belts for Y -> patented Non-planar printing -> patented I do understand why patents exist and their functions, but they are really holding back the full potential of 3D printing, imho. Both Tom and Stefan have been going through this topic on their podcast, several times...

@@andy_liga Yeah.. forgot about the patents side of these things 😔

but if the community just started building things without selling them would a patent really matter? 🤔

Exactly what I was going to suggest.

Tool-head clearance becomes an issue.

Would it be possible to show how to do the skewing in CAD before slicing?

@@shamusobi2748 Yes... or just a pre-processor on the STL.

Isn't that exactly what today's belt slicers are already doing?

It's the order of precedence that is wrong... those features need to be identified before the skew... but generated after it... so they're generated at the proper offset (angle) from the layer above.

Cura wasn't available when I wrote the first post processors... but it should be easy to modify it to do it in the correct order. Post processing won't do it correctly.

Hmmm... I was about to say it would also be possible to design an angled nozzle, but then the problem would likely be getting it to properly tighten at *just* the right angle

@@jasonking7570 you might also run into flow issues with an angle that sharp, you'd probably have to angle the whole hotend, and I don't know if that infringes on the patent that these angled belt printers avoid or not.

@@Redeemed1337 It really doesn't matter if it infringed on the patent since that only applies to products you're selling. You're free to infringe on all the patents you want at home for your own use.

@@xKatjaxPurrsx In the US, you can indeed infringe on the patent by just making something for use at home. Obviously, this isn't enforceable, but the moment you put that information on the internet... Well. Have fun.

@@Redeemed1337 citation needed...

That probably won't work. If you angle the nozzle you'd get better bed adhesion but your layer adhesion will suffer the same amount as the bed adhesion improves.

Just had a thought, what if you file the top of the nozzle at a slight angle? I recently had trouble with a nozzle I enlarged being slightly off-centre causing bulges on one side (roughly equivalent to tilting the hotend at the contract point)

The only thing I can see is the ability to have a machine crank out a run of parts without you needing to be there. I often would like to set a second print that would finish before I get back to the office, but someone needs to remove the bed and set it for the next part.

That’s a great idea. I wonder if that’s do-able.

Maker it has an patent on that until 2030 and they want crazy money for it.

@@FreeOfFantasy oh really!? I did not know that. Thats a pitty. Maybe ill get myself a printmill some day to mod into a standard style Cartesian. 😂

Same. Seems like one step too far with the CR-30. People would love serial production off of a regular coreXY.

To push that idea a little farther, I wonder how well it would perform printing lithophanes?

I've seen people use this printer to produce mass amounts of clips and things like that so its doable

Then the head isn't perpendicular to the layer anymore.

Why not just G code a regular core XY head to knock prints off? This belt stuff is a total gimmick

@@ianhoolihan2396 Belt printers are a regular core XY head. But I think what you're suggesting is to simply use a regular 3D printer movement system and have a way to knock the prints off. That's a great idea, and here's what I want you to do: Give it a shot and let me know how it goes. There are lots of people who have given it a shot and have had various levels of success with it. However, it's not 100% reliable for all models. A belt is. "So why don't we put a belt on a normal movement system". Yup, Makerbot tried that. But it adds another layer of complexity. In simple terms, it adds another motor. Whereas, a tilted gantry like this gives you the advantage of a belt, with it's quick part removal and "infinite z", with no additional motors or complexity. However, it does change the game, and has it's own set of disadvantages because of that. I wouldn't say belt printers are a gimmick. Belt printers are a new paradigm.

That's patented by MakerBot can't sell those.

Just G code the head to smack and remove the prints?

Z-axis optional 😉

@@MadeWithLayers Maybe use ink instead of filament :D

That's patented by MakerBot can't sell those.

You mean sanding the tip at a 45 degree angle? I think you could, but the nozzle opening would be oval, not circular. That might influence the quality of the print, since each "dot of plastic" deposited would be wider in one direction than the other. Also, there is a patent covering 90 degree angle belt printers and I think depositing through that sanded nozzle you describe might breach that patent. Because you now deposite at that 90 degree angle, even though the rest of the printhead is at 45 degrees. But I'm not a lawyer, so I'm not sure.

So a Voron 2 with a belt bed? That's patented by MakerBot can't sell those.

i don't think so, partly because of that makerbot/stratasys patent about it

That's patented by MakerBot can't sell those.

@@CutterSlade001 In that case, why not rotate the "core xy" mechanism by 90 degrees (and counter-rotate the nozzle), making it into a core xz printer with a belt. And if that's also patented, instead of putting a core xy mechanism over the belt, put a delta tower over the belt. That's surely too mad to have already been patented. Actually using the delta tower over the belt has some advantages. There are two main use cases for a belt printer: continuous production of parts, and printing large parts. Using the delta printer over the belt could work well for the continuous production of parts - the belt stays stationary until the part is complete, then the belt moves to dislodge the part, and then another part can be printed on the now empty belt.

That's patented by MakerBot can't sell those.

I show clarify I mean the print head axis. You could even rotate parallel to the printer axis, if you wanted to creat even heavier coding issues.

There are experimental heads that tilt upto 45° but the extra weight is limiting

agreed why not print a wedge type spacer the same degree as the incline of the x y rails have the print nozzle perpendicular to the belt and slice on a 45* or whatever angle your axis is set at ?

Interesting ideas. I had in mind some simple stepper motors to position the head, almost like automatic welding systems on a three axis arm, but far simpler.

@@mikeday5776 that would be interesting but I think a bit overkill just a simple fix the avg person can use. But I like your thinking.

It's only good for those 12 guys that are printing oversized final fantasy swords for their grandmas.

@@MoeReefs yep
