the whole printer has only been used since january, and all the nozzles are hardened steel. so i don't think anything has gone wonky with the hardware yet.
but switching to another head is a good idea. i'll try doing that.
yeah i figured that out. i ran some intermediates without and i thought the bumps were small enough that the ironing would smooth them out completely, but no.
i did that for my latest test and i don't know if it helped, but the default flow for this filament is insanely high compared to the default pla settings.
you know the weirdest part? i've now seen the exact same surface pattern on two test prints. it's not just that there are bubbles, it's that they are the same size and shape. and that's with different infill patterns; one rectilinear and one gyroid.
i sort of figured the gaps with the lower flow rate were underextrusion. i've already dried out the filament though. first for six hours on low heat in a snapdryer, then into my home-made dry box overnight. the dry box just a plastic bin with a hygrometer, a one-way valve so i can pull some air out with my vacuum, and one of those big-ass reusable desiccant bags for cars. the snapdryer read 10% humidity when i pulled the spool out, and the drybox is at like 11%. is that still too much?
as for temp, the official specs say it's good for 190-230C, and the preset runs it at 215. could that be too cold?
another think i've thought about when looking through the settings is that the preset for matte pla runs very fast. the "generic pla high-speed" preset runs at 18 mm3/s, "snapspeed pla" runs at 20, and the matte preset runs at 22.
good to know, i switched to gyroid for the next test and while the infill looks better the top surface still looks like ass. i'll attach a photo to the op.
but also, part of the issue is that the infiill just crumbles. i cut up the top surface and poked a screwdriver in there, and what come out was just powder.
are you sure about this? it says in the tooltip for the density field that it's "purely for statistics", to figure out how many grams of plastic will be used.
so this is snapmaker matte pla, the snapmaker orca fork has a profile built in for it... but it looks weird. the temps are off, the build plate is a little hotter than they specify on their page... i don't know if it's right. i'll do some cubes.
Edit: also, how can you tell the walls are over-extruded?
yeah "no great deed is commemorated here" etc etc etc. spooky stuff.
but... that's also true for asbestos. except it's worse because the moment you dig it gets worse, it can get into the water supply, and it doesn't stop being dangerous. it's carcinogenic forever. there are entire mining towns in canada that are condemned and cordoned off because of the risks of asbestos in the air.
like, there are as of right now two countries that have long-term storage plans for nuclear waste, and they both are "dig a big hole". ...okay? so just do that. there are thousands of abandoned mines that go down almost a kilometer where we have extracted millions, billions of tons of material. the total amount of nuclear waste ever produced is like... 200 000 tons. and uranium is dense, so by volume it's not a lot. just fucking dump it in an old mine if you want.
or better yet... don't! the fact that it is still radioactive means that it is still useful for generation. with the technology we have today, we can breed away like 40% into inert substances and new fuel. if we dump it all down a hole, what will happen is we'll have to dig it back up again in 20 years because it's too valuable to leave down there.
i used to live next to the biggest iron mine in the world, the luossavaara-kirunavaara mine. they have mountains of slag and waste product. far bigger than the actual mountain the mine is in. and in the mid-2000's, they started mining the slag. because there's still so much useful material in there.
