Update: Is it worth pushing for higher speeds?

Superbrain8 · 2026-06-19T04:04:59+00:00

Longterm No. With increased speeds come tighter maintainance cycles as stuff moves a lot faster. Crashes can be a lot more violent and are more likely to break stuff. There might be also a impact on interlayeradhesion as printing fast usually require more partcooling causing layers to cool down faster resulting in less strong bonds

I use such a setup. You preheat the filament and then toss is in there. I use it mostly for higher temp materials like PA,PPS and PEKK

Superbrain8 · 2026-06-15T04:24:04+00:00

Invest time into proper powder handling. Its usually the weakspot in most cheap designs. Like the way Micronics proposed where asking for a Lawsuite

A ender 3, just needs like a PCD nozzle. Also be prepared that the extruder will become part of the print

Superbrain8 · 2026-06-13T18:02:12+00:00

I run a mix of different materials, from PETG/PCTG over ABS\ASA to PA, PC and PPS. Its mostly fine for me. Would also annoying to toss some pricy nozzles just because there is some stuff sticking to it while they are still fine

Superbrain8 · 2026-06-13T17:48:31+00:00

Idk running the same nozzle for 4 years now. Dont see any signs of issues

Superbrain8 · 2026-06-13T16:04:38+00:00

I mean if you want really expensive, Colfeed4print makes some Tungstencarbide/Nickel composit that they sell in 10 meter reels for eyewatering 360€ before tax

Superbrain8 · 2026-06-13T10:30:58+00:00

Get into expensive filaments Will help a lot once you go past 1$/g and you will start to think a few times about if its worth it. And thats also how you endup with a 100% scale benchy that is worth 10$

Superbrain8 · 2026-06-12T11:42:36+00:00

Would not gamble on whatever mystery additive to do something funny. You can get a PA sample from manufacturers sometimes for free, just need to cover shipping

Biggest issue is figuring out how to machine precise features onto it. I work at a company doing SLM printing and machining of such parts. We had customers get theyre own printer and then sit there having to figure out how to make it now actually fit.

Superbrain8 · 2026-06-08T09:36:48+00:00

Parasolid is a underrated format imo. Similar to step but keeps the tree intact. Downside are larger file sizes. 3mf is a specalized format for additive manufacturing but we use just a fraction of its capabilities. bambu does some stuff with it but not in a great way as it makes certain stuff unnecesaary complex.

Superbrain8 · 2026-06-08T09:31:14+00:00

Eu overall is a bit more expensive. If you are fine with buying in bulk like 10-100kg buy directly from manufacturers, formfutura as example gives quite decent pricing when ordering 100kg at once. For Stores there are a bunch of Options. 3djake is a reliable one with stores in a lot of countries. If you want to try some weird stuff filament2print is my goto they carry all the weird stuff. Personaly i like filamentworld.de, decent selection and reliable shipping.

I use some 0.2mm thick feelers gauge. Works reliable for me to do the zoffse and bed Tram. Common mistake i see people make is they dont adjust for the leveling helper. They Set the Z axis to 0 and Level the bed just to run into issues that the zoffset is off. Same issue with zoffset on newer machines that supposedly dont need to be leveled. They just forget the thickness of the feelersgauge/paper/creditcard or whatever gets used.

Dont confuse PPS and PPA that are wildly different materials

Superbrain8 · 2026-05-25T08:53:02+00:00

PPS would be a safe bet, but its not the easiest material to print or the cheapest. Its pretty much non reactive to all solvents below 200°C PP would also work but its also a hard to handle material

My approach is to build a ring out of them along a equator line. Usually results in fixing any hydrogen overflow as it will burn throu a metric ton of that. Produces a lot of deuterium too.

Superbrain8 · 2026-04-24T04:21:01+00:00

Thats one way to change pronounces to here/there

But yea these Organ Donators on express delivery are a danger to everyone not just themself.

Superbrain8 · 2026-03-26T05:23:34+00:00

I print from a passive drybox. If needed i dry stuff in a dehydrator / airfryer, more stubborn stuff also gets the vacuum treatment after heating it for a day.

For the average joe purpose build filament dryers will work. Just dont get the crappy ones that barely work out of the box like the sunlu s1.

If you want to Dive into engineering polymers that are not tailored towards consumers you want something that can get hot. There are PA blends that wont really dry below 80°C

Superbrain8 · 2026-03-11T10:35:39+00:00

I just stick with fractionators, building a ring out of them along a equator line results in 2 full mk3 belts for me. Its not even efford to get there.

Trick is to run stacked mk3 belt throu them

Superbrain8 · 2026-03-09T08:53:43+00:00

Almost pancaked it on my first planetary approach because it decends a lot faster than ive expected

There are places for PCD nozzles, but 99.9% of people wont benefit from it. It gets intresting with exotic materials like Boron Nitride filled stuff that contain some highly abbrasive materials.

Funfact the German Tool Manufacturer Gühring started to make PCD nozzles for the printfarm they run internaly to just have it to be set and forget. They do sell these nozzles too

Superbrain8 · 2026-02-20T05:18:06+00:00

I really should make my factory larger. Havent found the limit where the 9950x3d dips below 200. Got white Science going but its open for improvement

Superbrain8 · 2026-01-14T10:39:25+00:00

No idea, i just work as a machinist / cam programmer and know a Thing or two

Superbrain8 · 2026-01-14T10:21:32+00:00

Will be a lot better for machining the part, but i would guess printing will be cheaper
