  • The primary concern with fdm printed parts is bacteria growth in the gaps and cracks, which you cant really avoid. Some materials allow vapor smoothing, but the most popular candidates ABS and ASA are not food save, even if perfectly smooth.

    For storing stuff that does not support bacteria growth (for sure salt, maybe tea bags and pepper) PETG is a good choice. Strong consistent layer adhesion enables water tight print. Its relatively chemically robust and will not chemically react with your food, and not leach out much if at all. It also means its mostly dishwasher safe, especially at low temperatures. You MUST have a properly tuned PETG profile to get a close to perfect surface with minimal defects. Burn of any stringing, otherwise it will end up as microplastic in your food.

    For storing stuff that can spoil, the requirements are a lot higher, and the only option is coating with a food safe resin. You should research what is compatible with the printed plastic, and maybe avoid dishwasher or aggressive cleaners.

    It’s worth it for the dry storage and automatic loading alone. Printing multiple objects one after another on the same bed and same print job, but with different materials is also a great feature and huge time saver for small parts. For actual multi-material prints the best use cases are imo writing into the first layer with a different color or using 2 different non-adhering materials for a thin layer between supports and the part. All of these things require very little filament changes and significantly improve the usage experience.



  • You are doing it wrong. Framework is easy to DIY, use that option and bring your own memory and storage. Only get what you need right now, you can always upgrade later when prices come down. Instead of the included charger, get a high quality third party 65W GAN charger. All that gets the cost down to about 1600 with barely any downside. Don’t buy a modular device without using the modularity to your advantage.


  • lol. Look at the current state and trend of tech and tell me with a straight face that it’s you who will be getting the innovation. What amazing feature was introduced in the last 10 years you couldn’t live without? How much garbage was introduced just because companies could get away with it because the average consumers PC is powerful enough to not notice the spyware/adware/bloatware running in the background?

    Yes, buy the new thing. Consume. Trash. Buy new.

    I don’t even value repairability to save a buck long term. I value it because I know I can get my system up and running again ways before I finish setup on a new device.




  • Agreed. If you buy the minimum spec bare bones version and get RAM and NVME from a third party, the price is somewhat comparative to other MRSPs. If you go for a higher spec or compare to sales prices instead of MSRP you pay up to 50% premium according to my research.

    If you however factor in downtime of a broken and non-repairable device, plus the time spend on setting up a replacement, the framework can easily compete if your setup is complex.








  • People joke about this all the time, and I here the sarcasm in your comment, but technology has come far since the iphone 6 or 7.

    Most high end phones have wireless charging build it. Between the receiver coil and the rest of the phone is a thin sheet of ferrite material to prevent the electromagnetic field from getting to the sensitive electronics. Battery technology has also improved a lot, so much that even relatively cheap phones like the Realme GT Neo 5 charge at 150W!

    From the technical perspective the limit is the cable and connector, because there would be too much losses that heat up the cable to dangerous levels and rapidly degrade the contact area in the connectors. Manufacturers don’t want to deal with this security risk, not the increased RMA rates within the mandated guarantee period, so they artificially limit the charging rate.

    Thing is: You absolutely can charge at higher speeds if you bypass the cable altogether! A microwave outputs usually somewhere between 150W-1000W, so stick to the lower end to be on the safe side. The screen of the phone must face down, because the charging coil is placed on the back. You also must prevent overcharging by setting the timer correctly: If your phone battery has 15Wh capacity, and you are charging with 150W, you must at most charge for 1/10 of an hour, or 6 minutes (less if you are just topping up your phone).

    One final note: fast charging does put increased wear on the battery, so I only recommend to use it when you need it, for example when you need to make a flight and are already running late.


  • I am aware of the basic arguments behind inflation/deflation, and neither is good in excess.

    Typically central banks targets inflation of 2% these days, but we all know the real inflation for necessities is far higher (>4%). Inflation disproportionately affects the poorer - rich people have the fast majority of their wealth “stored” in stocks or real estate, which rise in valuation as people rush into these markets to protect the little they have. I’d argue that inflation rates are artificially pushed far higher then is sustainable, simply because those who decide are the same people who benefit the most.

    I consider a low but predictable inflation rate about 1% ideal (0-2% is acceptable short term variation) for the following reasons:

    • No one has to worry about debasing/devaluing your currency by injecting more supply.
    • Nobody “passively” gains wealth by sitting on it.
    • If you want to keep your wealth, you have to take some risk and use it.
    • Inflation rate is not so high, that you need super high risk investments to keep up, making it more accessible to small players.
    • Large player can not as easily game the market by skimming of value from the lower to upper middle class.

    Yes, this idea is not without risks. But the way I see it the forced “we have to improve value by 2% every year” exponential grow can only go on so long before we (humanity) hit the finite limits of this planet.
