  • 3D Printed TPU Gaskets? -- Follow Up one year later

    Jump

  • Most of the gaskets I've made are for oily things and I'm not sure all would be clean enough and/or fit on my flatbed. That does sound like a very fast/effective method though! Especially if you found yourself needing to do this fairly frequently.

  • Na, functional prints are great! You just have to be wary of "now that I have a big hammer, every screw looks like a nail".

    I do a lot of prototyping and one-offs with my printer that I just wouldn't make without it.

  • Is there much difference between Temu, AliExpress and Ebay?

    Jump

  • eBay and PayPal were independent companies. eBay purchased them in 2002 and spun them off in 2016.

    I have low hundreds of transactions on eBay and am generally pretty OK with the experience. I don't understand how people sell on there, especially new products. eBay takes a pretty big slice of the pie, followed by PayPal and friends. Buyers expect free shipping, which also eats into margins. If you choose to charge for shipping, eBay will also take the same commission percentage out of shipping costs. This means you still lose $$ shipping, but you are losing less than you would otherwise.

    Selling used stuff makes a lot more sense financially, but eBay will almost always side with the buyer should a dispute occur and not all buyers are good faith actors. This keeps buyers coming to the platform, but it is hard on sellers.

  • I love me some 3D printing, but if you need a fast gasket I would buy a roll of gasket material and cut it to size. Most auto parts stores stock a variety of materials for this use.

    Gasket mating surfaces can be... extremely fickle, especially when one of the two sides is stamped sheet metal or even plastic. Too little torque on the fasteners means there won't be enough clamping force, which means leaking. Too much torque on the fasteners will dimple the stamped or plastic part, which means leaking.

    If you're using this in a low temperature application with beefy mating surfaces, TPU could work fine I guess. It still seems like more effort to get a dimensionall accurate enough design than to grab a roll of gasket material and an exact blade.

  • Thank you for the information! I've been wondering if I should put the print head in a consistent location while waiting for the printer to heat soak. Sounds like it won't matter a ton.

  • Knocking is usually pre-ignition and higher octane fuel will reduce that. Knock sensors are one of inputs to the engine control algorithm's "how much can I mess with timing" game.

  • What is something you only experienced once and would like to experience again?

  • It could also be that you're getting older and you're developing a wider world view. I've been a corporate shill for a while now. When I hired in there were a lot of messes, but I was young/optimistic/saw a lot of opportunity and was rewarded when I cleaned things up. Over a decade later, this place is a mess. I'm coming to think that it's stuck in a rut of process/technical debt and Conway's law and that even though leadership has been saying things are changing for the whole time I've been here, we're really just getting more entrenched.

  • Cheap, low-effort, perfect filament splicing method

  • Epic follow up. We keep parchment paper on hand and I'll give this a go when I'm getting near the bottom of a row. This will be much easier than feeding the new role in mid print.

  • Do they show reasonably consistent temperatures? I've often wondered if I should have my thermistor at a fixed z height.

  • Given BambuLabs recent issues what now?

  • Mine also came with premade harnesses and all the necessary PCBs. Granted, I chose to cut the harnesses down in length so everything under the bed was a bit cleaner.

  • There's very little to run at your fuel consumption rate, so go for it!

  • After a year or two of being scared of first layers it feels so good to not worry about them anymore!

    Jump

  • I bought mine from Best Buy, but you're right - carriers don't offer them anymore.

  • I'm wanting to recycle household waste, where is PLA plastic used in packaging?

    Jump

  • Both grinding input plastic and then extruding that into filament can be challenging to do consistently/well. It also doesn't seem worth the $$ unless you're able to do so at a commercial scale - you run a print farm, you're looking to set up a local(ish) filament recycling scheme, etc.

    If you have the time and funds, it does sound like a pretty good rabbit hole to go down.

  • I am with you 100% and you're living the dream. I am jealous, but my present commute would never accomodate this :(

    Higher octane gas is not more energy dense than normal gas. Octane is a measure of the fuel's ability to resist combustion. Some more highly strung engines require higher octane fuel. Others will run fine on "regular", but have sensors that enable them to do things like advance the ignition timing, change cam timing and phasing, etc to make more power with higher octane fuel. The final camp of engines is optimized for regular fuel and putting higher octane fuel in them won't measurably impact performance (power, fuel economy), but it might make the engine sound a little nicer due to reduced pinging. Not that you would even hear that in a modern vehicle thanks to all the optimization and sound deadening.

    But! At $2/week in fuel you have very little to lose. If it's fuel injected and has coil on pack ignition, it might even be able to take a touch more power by running more aggressive ignition timing.

  • Very nice!

    Mine is a 350, so yay lots of panel surface area :(

    Where do you have your chamber thermistor mounted? Mine is mounted to the top of my stealthburner.

  • It is a 2.4 and I do have a klicky. I run a Z Caliberation macro that makes it a lot less fiddily to deal with getting offset just so. I could see using klicky to be the z end stop, but I'm done tweaking things for the time being. Maybe in the next go.

  • We have a 4 and 7 year old and keep the first floor between 63-67 °F. I also realized the Celsius temp above has a typo, it should be 15.5 °C and not 25.5. That would indeed be warm, lol.

  • BOM in a box is absolutely they way to go IMO. I ordered a customizable kit from West 3D and it contained everything I needed and more.
