@muhasaba_needer @TimmySeto And all of that coolant loss! It's like a sponge that never let's go of it. Just all around nasty stuff to deal with.

@TimmySeto strongly dislike dealing with acetal disposal because of the wet chips

We keep lids on those Uline receptacles, the smell is terrible. If you are machining Delrin (acetal homopolymer), choose your coolant carefully. It will make the smell far worse as it has the potential of degrading in strong alkaline environments. We don't let the chips linger, they have to go out to the dumpster at least twice a day. The gasses are trapped in the chips and will continue to bleed out for several days. Again, coolant could compound the problem!

@jrhartman131 Wow! I've actually got a long way to go before I'll be making guides that long. Nice work sir! What's the length on those?

@67Designs @josefprusa They were happy for the nearly instant delivery, and that's the lesson. I'm not picking on China, they are following the same path that lead US manufacturing to ruin. You can't paper over the logistics when it makes sense to pay me $200 to print $5 in filament.

They must be happy you are doing the prints on a Bambu from China. Shame it was not on a @josefprusa . I think Bambu now dominates the FDM arena. It is stunning how they swept in on the Prusa ecosystem and ran away with the market. There is a massive lesson for every single Western manufacturer when it comes to opensource and trust that all cultures are cut from the same cloth. In fact what China did with Bambu was classic target-n-leapfrog. They did it with drones and no surprise it is ex -DJI execs that drive Bambu. The next space in additive that is in the cross-hairs is SLS and vapor smoothing. The lawsuits are already flying in the U.S. courts, but China has a playbook and I would not be surprised if Bambu delivers an SLS printer platform.

I just sold some 3D printed parts to a 50% Chinese owned multi-billion dollar manufacturer. We printed these PETG fixtures for their quality department on a Bambu X1C. It's been a very weird year.

Many customers are now requesting kitting and light assembly. Easy enough if you're running high production like this but it gets complicated with low volume. Humanoid robotics might solve it but we're thinking along the lines of highly customizable mini machines to do the work.

@Systematic___ Nice. Due to axis accel/decel our actual cycle times have taken a bit of tuning in, a long time problem we are hoping to solve with machine feedback.

@amer_icon they are based on machine specific rapids. i have yet to confirm cycle time accurately with a stop watch. however have compared identical profiles on mazatrol and the cycles were within 1m. (on 52 minute cycle)

SaaS? Never heard of her. We're just quietly building for ourselves. First widget installed on the new whiteboard. Hovering on an item will show all release dates and how far away they are. The goal is no red on the board. My nephew is just killing it, they're gonna be alright.

there are parts of vc culture that are deeply wrong. they create very unrealistic expectations. i recently had a chat with a young founder in his 20s. he's been building a CPQ software in industrial manufacturing for 3ish years and is struggling with long sales cycles, small budgets and slow adoption in a legacy industry (sounds like job shops i know). somewhere, maybe from the vc world, he got the expectation that he can build something in 3... max 5 years, grow it into a $10–50m+ business, and exit by year 5–7. anything good in life takes time. startups, especially in manufacturing, take decades. the best companies i know reached significant milestones, whether revenue or an exit, in years 10-20+. it might be hard for younger founders to digest. 15 years ago, i thought exactly the same way. i would've never imagined i'd still be building the same company 12 years later. never. it's just the wrong expectations created by a culture obsessed with short-term growth and quick exits.

its very easy to blame the people who raise VC money. call them grifters. say that kind of money is completely out of reach for regular people, especially in manufacturing. obviously the AI bubble and the huge AI rounds just add fuel to the fire and get people mad. but just a reminder: no, it's not easy to raise money. especially the first time. it's never easy. and you have no idea how much harder it is outside the US. sometimes 10x harder. you also have no idea what happens to you if you, god forbid, fail your company. the US is the only place where failure isn't quite the end of the world. it's experience, and people actually cheer for you to do better next time. and even here, for someone who moved from outside, building a network from nothing and raising money is extremely hard. 99% fail even when they try damn hard. i raised my first 25k after two years of endless drives to SF, hundreds of meetings, accelerators, and 1000s of no's. and the thing is, i was building this silly little saas in manufacturing in 2017 to 2020, back when 99% of VCs couldn't care less about the space. not to mention my confidence and my english at that point were... well, sub-optimal. so no, it's not like you show up to the market, it rolls out a red carpet, you say "i need VC money," the money arrives by the boatload, you take it and build another dumb saas. instead of truly struggling for decades, poor but true to the work, moving atom after atom, never taking a dollar of VC out of principle. most people i know who raised did it through pure grind, after 1000s of no's. and then spent 10 to 20 years building something that may or may not turn into something big. either way they went through every possible up and down. ran out of money. almost sold. lost the big customer. all that kind of shit. maybe i was just lucky to only know people like that. don't get me wrong: a VC round isn't the biggest achievement compared to say revenue. but it still matters. you create jobs. you develop the market. you build something people actually benefit from using. and i respect (and you should too) that kind of person and that kind of grind.

@Systematic___ Endless customization for the users is a fantastic goal. Once you start asking for feature requests, they never end lol. Nice work, are those estimates or are you reading machine data?

cool. i have built a few machine shop tools. inventory for tooling / inventory / receivables for material. and currently building a programming UI. originally built it for complex engraving (we do engraving all parts HT+PO+sometimes serialized).. and it is turning into a monster. the options to customize the shop and how data flows is really endless with the ability to build user/shop specific dashboards / tooling.

There is this lie that America lost its edge and doesn't know how to manufacture anymore, despite showing everyone else how to do it. And the other great lie is that software is going to be the big "reindustrialize" moment. If VC's aren't seriously discussing the problem, they're grifting. I have no idea if this is related to the latest thing.

Here's how standby lead-times work: We significantly drop the price, and then set a longer guaranteed lead-time. BUT, we group your parts in with other standby and standard orders. Your parts will usually ship much faster. You get lower prices, we get scheduling flexibility.
