It does work. Just not very well. Not enough to be widely usable. If it was an idea it wouldn't have thousands of lines of code and working binaries. 100% infill doesn't remotely s…

Yes. It's a modified triangle infill pattern. A solver pairs the triangle with one of its neighbors. Then cuts a window at the bottom during the slice. So plastic gets injected int…

Because that's not accessible. IMO the reason other efforts to achieve similar Z reinforcement have gone nowhere is because it was one guy fiddling with G-Code. All the big innovat…

Thank you! A lot of people here took issue with the crappy docs. My mistake, I barely spent any time on them. The reason this "came out of nowhere" is because I was working on it i…

because the plastic has to displace air. This method seals the nozzle against the tube and injects under pressure (theoretically). And leaves a path for air to escape. Pretty much …

Z layer weakness is the main reason that 3d printed parts are brittle and much weaker than injected molded ones. This is meant to knit together the part in the Z axis

You can set the tube height to like 4mm and that's pretty much what you'll get. The tubes only need to be tall enough for a "window" at the bottom and a splitter in the middle so t…

Resin would be very interesting. The tube design seals them everywhere below the top layer. And the two ends of the tube tops are always at the same Z. You could technically inject…

I did some basic calculations on isotropic heat loss in a circular tube. I don't have the knowledge to model it in detail but I don't think this is correct. You can set tube height…

It's more than that. I added a SAT solver to refine the tube endpoints so that nearby tubes don't start or end on the same layers. Even the default greedy solver (CP-SAT is SLOW) d…

The post was from a week ago. Must have been refreshed by the algo (or admins) for more visibility. Originally never got any comments. Have you looked at the code or tried the bina…

The injection probably happens faster than you think. With a high flow hot-end and 5mm deep channels its reasonable for the injection to complete in less than a second. > How are y…

> The problem that the author is describing is that the plastic is actually far too hot when injected and causes wall collapse. This is because the author isn't taking into account…

The filament is injected into tiny triangular U shaped channels, about twice as wide as the filament diameter. The depth of the channels is configurable and you can go as shallow a…

No, unfortunately. I've printed a ton of objects but nothing clean enough to be interesting. The top of cells always melt as I'm using the same material for injection and the rest …

Here for any questions about how it all works :).

Commodity FDM print strength is limited by poor Z-axis layer bonding. Parts crack along Z under stress. MAGMA tries to fix this in software that works on any FDM 3D printer. It's a…

Google's Guava Bloom implementation is very well tested. I suggest looking at their guava test GitHub repo. They even use pre-seeded and manually verified filters as controls as so…

Depends on the language I guess. The most efficient way to represent buckets is to pack the buckets right next to eachother in a giant memory block made of bits. The other part of …

No problem, The paper authors left a lot of the specifics off... I got burned by the victim cache too. I saw one in their reference code and thought it was pointless until weeks la…

The code should use bits, the point of the filter is to increase space efficiency so you need to pack everything together as close as possible. Having fingerprint sizes of only mul…

Hi there, I've wrestled with Cuckoo filters myself, so I took a look at your lib and there's a some things that stood out. Fingerprint size- It allows fingerprints that are too sho…

The thing with Cuckoo filters is that the item's alternate position is determined solely from it's current position and fingerprint. Mathematically this is done by XOR'ing with a m…

Hmmm.... this might be an artifact of the python implementation? The insert speed should be roughly constant until the filter begins moving items into their alternate buckets(when …
