They dont show really how they work… I wonder which pros and cons this type of printing has, or if it has any advantages compared by a classical stereolithography printer

Given the feeding frenzy of new printer companies looking for money over the last year or so, my default assumption now is that showing a content-free promo like this means that you’re not sure exactly how it’s going to work either.
There is no such method like helio lithography. Can you explain more about the method of making this process continuous?
This is not “heliolithography”. This is stereolithography, with a spinning build plate.
It is a newly coined term, since they created the process they’re perfectly entitled to rename it. They’re not claiming it’s not SLA, they’re claiming it’s a new subtype of SLA. It’s just like using the term Delta to describe extruder printers, it doesn’t stop being an extruder, you just know which type it is.
As for differences…
Seems like there are some, but how meaningful they are or aren’t /shrugs/
@ThantiK It’s a little different. I’ve been publicly theorizing for years that by constantly moving the vat (or in this case, the platform), such as with a spinning motion, you should be able to recirculate resin under the print without pulling the part up each layer to allow resin to flow underneath, allowing continuous DLP builds with the layer height limited only by the projector’s FPS. This video tells me three things: I was right, some fuckheads are trying to patent it, and they gave it a stupid name.
@Whosa_whatsis so gather your posts and submit them to contest the patent claim
I was just about to post my speculative thoughts but @Whosa_whatsis pretty much nailed it. Very similar to the “spiral vase” option in slic3r.
@Daniel_ShadowDrakken , It’s as if I were using a Delta printer, and instead of calling my fabrication method “Fused Filament Fabrication” or “Fused Deposition Modeling”; I called it “Delta Deposition Modeling”.
It’s not a new process. No, it doesn’t deserve a new name.
Ok, so stop using “car”, “truck”, “van” and “SUV” since they’re all already named automobiles
You don’t seem to be understanding. “van” and “suv” are different types of vehicles. Not different methods of propulsion.
If they said that this was “Constant Motion Stereolithography”; I could agree. Because it’s still stereolithography.
“Helio” is of or relating to the sun. “Heliolithography” would be using the sun for manufacturing. Words have meanings for a reason.
really? The only difference I see is size. Other than that, they all use combustion engines, a frame and wheels. They’re more identical than HL and SLA are.
It’s a good thing that heliolithography isn’t actually a thing then!
It is now, they’ve coined it and are patenting it. Get over it, or challenge the patent.
When I first read “heliolithography”, I thought it must mean that they’re using selective application of sunlight to polymerize the resin. Turns out they’re just idiots who don’t know what words mean.
They were probably thinking helical… and failed… so yeah, the name sucks, but it doesn’t change that they can name it whatever they want
What would you call it with more than 2 lasers?
Moving the platform or circulating the resin…if they move the platform and patent that, the someone else can move the resin and patent that. Hopefully, a kickstarter happens to fund the research with a goal of open sourcing it and cancelling the patent.
Making a new one that does the same thing now would violate the patent when it’s granted. You can’t contest a patent by copying it.
If you want to contest it, it has to be done with prior work, which means people like @Whosa_whatsis who have publicized the same method in the past are the ones that need to collect up their evidence and submit it in challenge.
Only for right hand turn blades. I see massive structural failure on anything that had hydrodynamic drag.
Hmm,strange ,the solidification begins at the bottom of the vat,so you need to wait the solid piece grows to the part.If the head is turning continually there is a risk of displacement of the growing piece.I can imagine the vat full of small solid pieces at the bottom.But probably they have overcome this problem.Or maybe this is the reason that we are watching only the animation,not the real product.
