MCUs can run Linux.

I don’t use Espriff products so no idea if it is available for the ESP32.

A lot of people (probably) would have chipped in and be happy with a half-backed first-generation product. People loved the Ender 3 and even accepted the Anet A8 which would catch fire if not modified because it was all they could afford/buy.

Look no further than Micronics sift bin. It was jankey but it was what it took to hit this price point and people accepted it.

All of the buzz was about SLS being finally headed toward enthusiasts and small businesses. Adoption/market size getting bigger and suddenly good SLS is affordable in the near future. All of this was killed with this acquisition as FormLabs is the wrong company for this trajectory. Even the fact that FormLabs is asking $4k for the * privilege * to use third-party materials is a strong indicator.

Do we expect anytime soon that FormLabs will beat what is already out there? Sinterit Lisa: $10k: https://sinterit.com/3dprinters/lisa/

My money is on that the next/first budget SLS will be made and engineered in China. I don’t know who will be next but it likely won’t be another startup in the west.

The whole ecosystem here in the West doesn’t favour starting up. It’s not easy to do it in China either, but the whole supply chain is there (as such also the knowledge/support) and the business environment makes it more likely for it to happen there.

Might be a restructuring:

The issue with Weller is their price in a competitive market.

Considering no alternative the entry level Weller is fine. Ersa has their awesome itool with this really short distance between soldering iron tipp and finger grip: https://ts.kurtzersa.com/electronics-production-equipment/soldering-tools-accessories/soldering-desoldering-stations/produkt-details/i-con-pico-1.html

Performance: Weller and Ersa are more or less equal. For generic solder joints both are great. If there are high thermal mass and it isn’t possible to use a large tipp than the Hakko T12 is the superior technology. Changing tips on the Ersa (while not recommended by the manufacturer) can be done with the iron heated up and tool free within 5 seconds.

Ergonomics: 100% Ersa. The only reason it has been my daily driver for half a decade and is here to stay. Before this station I actually had a Weller.

JBC has a similar tool handle to the Ersa but those are very expensive with little benefit.

The price to performance king are genuine Hakko T12 tipps with a China station.

How about a 3D-printer that prints its own z-axis?

The disclaimer says they’re trying to get it approved which implies they believe it could be

That’s a tough one and I doubt they will succeed with this. As far as I know, they would need to certify a material + process (3d-printer & settings, slicer-software & settings) + 3D-model combination. Far easier to certify a product containing 3D-printed parts than a 3D model/file.

Plastic is the wrong material due to moisture building up inside and some other pitfalls.

First of all: Legal is the bare minimum.

If you run a contest or sweepstakes and set out rules you are bound to them. Ignoring them like Prusa did exposes you up to liability claims.

You’re mad that the contest was moderated?

More the opposite. The sloppy way they moderate it to the point where they don’t even bother to remove comment spam below the contest description page.

Voters voted on the submissions they liked the most. Get over it. Voters voted on the submissions they liked the most. Get over it.

That’s not how it works. There is no public vote.

Honestly I stopped reading. Something about a paid part integration that you got mad about because it’s heavily discounted and you can submit photos even if you don’t have one or something?

Just read the comments here: https://blog.prusa3d.com/contest-experiential-robotics-challenge_97306/

Dozens feel like this isn’t a good choice.

Btw. I don’t take part in them but it is still very ugly what they do. Similiar you don’t need to buy Nestle to understand that Nestle might be problematic in some aspect.

For Germean voters there is the WahloMat to help with the voting choice (a dozen of questions and in the end shows how much overlap there is with all the parties): https://www.wahl-o-mat.de/europawahl2024/app/main_app.html

The major issue is that if you care about CopyRight: Party A. Easier to comply with regulation: Party B. Migration: Party C. Environment: Party D.

And all of the choices (A-D) have some very removed, prominent positions that you strongly oppose and in the end, have no clue what to elect and choose the least worst option and hope for the best.

I don’t lube the rails, it attracts too much dust. I still oil them to prevent rust.

Some aspects of Printables are “wrong”. Contests are a total mess at the moment. I might make a serape post about it.

This? Looks like a glitch/bug. As far as I can tell this is only active on paid items which makes sense.

If cold pulls won’t work get a new nozzle. Filament of choice for this procedure is Nylon.

One of the alternatives could be THF to dissolve the plastic and go from there. Don’t know what Prusa charges for nozzles but it can’t be that bad to make this procedure worth it. After all it is a Prusa and not some industrial machine.

Improved but still not a match to Ultimaker Cura.

Prusa is very slow compared to Cura as PrusaSlicer needs every option checked including Geometry handling accurate to sometimes get 7 pcs. matching Cura performance. If the result is 7 or 6 pcs. depends on where the part originally was placed on the print bed (or luck? run to run variance?). Not a reliable software for nesting.

With fast and balanced setting it only does 6 pcs.

fast:

balanced:

accurate:

Default settings. Where is the option to rotate it?

Providing it manually with 90° rotated and using the auto arrange instead of fill bed: 5 pcs. Still not a great result.

Cars are a very high-vibration environment with km of wiring and some carrying high currents, flammable liquids and hot parts. With e-autos there is even more including a 50’000 Wh energy storage waiting to catch fire.

While cars do catch fire it is unlikely to the point where they don’t need fire suppression systems.

Some cars have fire suppression systems but those are race cars. Built differently to maximize performance. (or military vehicles)

Similiar there are 3D-printer that might benefit from a fire suppression system but the run of the mil 3D-printer won’t need it.

Not convinced? Look at CNC-mills or swiss lathes. Those are designed to run nonstop for years in a production environment at the highest speeds to maximize production. Most of them don’t have a fire suppression system (they do have a mist extraction/collector to prevent them from exploding).

I like BambuLab. They handled the issue seriously. Resolved it and now it is fixed.

What I meant with low end China is like QIDI-tech having exposed 230V (not fixing it), Tronxy choosing high and low voltage wires with the same color and no PE connection to the chassis, Ankermake having issues with the heatbed insulation (not fixing that either) and crushed wires. That’s just three examples and don’t expect that other companies are better. BambuLab is a rare exception.

Once you teardown “industrial”/professional machines the point of view changes: PE connections, strain relief, drag chain rated cables with appropriate bend radius, crimped ferrules instead of solder on wire ends, … they are built to last and run 24/7 without catching fire…

The best protection is a machine that is well build:

We have ovens in our kitchens that are designed to reach upto 400°C (for cleaning) and nobody is afraid of them catching fire. Why? They are engineered to be safe.

Similiar a 3D printer that has good engineering is safe and doesn’t require an automatic fire extinguisher.

If we talk about low-end China printers then the answer is they might not be as safe but the solution is to fix them instead of adding the fire suppression system.

Watch your attitude.

I think you still somehow assume this is some kind of ad to sell this design for money or I am a jerk for not just publishing it with source files.

Also not everybody spends their time designing and publishing whatever is popular at the moment on Makerworld to collect points/store credit. There is a different world that doesn’t run on Fusion360 source file most people could edit and can design parts with a particular material & print(farm)/process in mind to get the most out of the FFF 3D-printing process.
