  • Your argumentation doesn’t make much sense; indeed your last sentence even reinforces my argument that, hopefully, the process is as clean as possible. Also don’t you think you’re a little bit quick in assessing my priorities based on a single comment? 😉

    I think 3D printing, as many things, is a net positive if used responsibly. It’s so easy to repair or upycle stuff with it. I’m also really interested in that pure PHA filament (which is actually compostable, unlike PLA), haven’t gotten around to trying it. Of course also using PETG; got two huge bins for PLA and PETG to collect and send it to Recyclingfabrik (getting cheaper rPLA & rPETG in their shop in return). It’s awesome how easy it is with 3D printing to have a full recyling circle. I think awareness for both environmental impact as well as basic safety concerns are really falling short in the community though. The amount of people sanding their prints without any particle extraction system, printing ABS and stuff without air filtration or even work with resin without proper respirator is concerning. And so many people just clean their sanded pieces under water, unaware of the consequences (it’s impossible for huge filtration plants to fully filter them out). On the other side it isn’t too hard for any 3D printing hobbyist to run their dirtwater through something like a coffee filter.

    So yeah, I like 3D printing and the environment and am optimistic we can have a cake and eat it too. 🥧


  • […] Polymaker’s HT-PLA-GF, a glass fiber high temp PLA that can be annealed in boiling water without deformation to withstand temps like 150º.

    That sounds like a microplastic water risk. I hope Polymaker did at least give a little shit about the environmental aspect and made sure the material doesn’t leak into the water during the process. Probably still advisable to pour the waste water through a filter afterwards, just like after sanding & cleaning.

    That’s just because we made it like that though for some weird cultural reason (as well as propaganda), there’s zero reason why an office worker or train conductor couldn’t eat multiple small amounts of fruits and veggies over the day, or just none at all until home. Even the idea of the “importance of breakfast” literally came from Kelloggs trying to convince everyone to eat cereal in the morning 60(?) years ago to build themselves somewhat of a ‘cultural anchor’. I mean, we could’ve also gone the way to chop each workday in 2-hour chunks and eat a bite between all of them. Good thing nobody told Nestle they could’ve made people buy more food that way.

    This. I really only eat a small breakfast because I have to for meds, but if it weren’t for that I’d totally be fine with one big meal a day (turns out to be dinner most of the time) and perhaps one apple or sth. late at night.

    This forced 3-meal system is so weird and inconvenient.




  • Those problems are being fixed with newer vehicle designs though. The charging speed (the 800V systems seem to reach sub 20 minutes consistently by now), range (450+ km appear to become normal, the more fancy ones even got over 650km) and economics (battery packs become repairable and way more affordable even for a full replacement, especially given the savings in other expenses compared to ICE) seem to check out. The main problems are infrastructure, lack of affordable second-hand options… and honestly that stupid idea that cars should be our primary mode of transportation. Damn, we even got viable alternatives to lithium-ion batteries by now, that technology didn’t properly evolve for half a century or sth.

    The data on battery longevity is also promising, they stay at usable capacities way longer than expected. Those first generation EVs just age really poorly given they’re, well… first generation. The technology is developing at breakneck speeds for the last decade.

    On a sidenote, don’t let anyone tell you european EVs are somehow worse than chinese (they are not). They’re just more expensive due to a fortunate lack of slavery, and generally higher standards of everything in the production chain compared to China.


  • The emissions part I’ll have to agree on, but safety? Germany is literally among the safest nations to drive in. There’s not much lower you can go.

    Always room for improvement, especially if there’s such an unnecessary reason it’s “only” 16th place. Regarding EVs: You didn’t really acknowledged the economics arguments but simply assume that ICEs will be faced out. Which might still be true even in the worst of all economical situations, however my argument also entailed that people want to buy EVs. Giving ICEs and EVs equal footing in a “free” market is a good thing unless you want offset not doing so with a heavy hand with more regulations. One way or another we need this change asap, so a regulation that’s literally everywhere but here, has support from a majority of people and benefits every cause there is makes the most sense if you ask me.

    “Top 10 in road safety” also has a nice ring to it.


  • and for people to always check their mirrors before switching lanes.

    Oh, I wish. I don’t think your expectation of adapted behaviour is correct on a societal level, and given how many deaths could’ve prevented by a speed limit… people drastically overestimate their abilities and underestimate the speed and force of impact all the time. If the road is going slow right now or someone missed their exit people will still drive like maniacs. Not to mention that there’s also other good reasons for a speed limit, environmental and economical (with ICE cars you don’t immediately feel how much more you’re paying in money and convenience/time, but EVs will tell you that immediately = more CO², more costs individually and for society, less sane car purchases).

    I don’t think strict TÜV, training etc. is connected to a lack of speed limit either. It’s more of a cultural thing in society, and of course to politics and how well people are off.

    I get your opinion about preserving existing freedoms. It’s always a balance, however in this case I think this personal freedom to go fast is in no relation to other people’s right to save travel, and future generations’ right of well-being.



  • I mean, the US really isn’t a good example for road safety. Even Germany got better drivers, and we like to drive 140-200 kmh. It’s a matter of good education, standards and regulations (as always).

    In the end self-driving public transport is the way the future of mobility should primarily be imho. Self-driving cars… as long as there always is a steering wheel in case of unexpected circumstances or to move around backyards and stuff it’ll probably me fine. Just don’t throw technical solutions at cultural problems and expect them to be fixed.



  • Well, they arguably can also be used as one big long-term storage. Not sure who’d need to save so much data for a long time, but there surely will be at least some people who do and buy the “modern solution” over old HDDs thinking they’re better in general. As the “family backup” for example, or as cold storage solution in faculties that can be quickly accessed if needed.

    Read somewhere about a professor who used SSDs to “permanently” store important data on SSDs (perhaps in the comments of the article above) for a few years. Well, wasn’t that permanent…
