everyone's talking about shenzhen iteration speed. half of it is just that the shop answers ur message in 10 minutes. that part doesn't need to be in china.

elon made a car fly tonight. i spent mine telling a customer we can't do a sharp inside corner. same industry technically.

got asked "what are u building" 5 times today. told one guy i'm building patience. he asked about my burn rate.

every week the parts get a little harder and the problems get a little weirder. not complaining.
the more we build, the more problems we run into but that's part of the fun
almost feels like we're aura farming at this point
just go to 2426[dot]parts, if you want metal parts
[sound on] for this week's vibe

one of the biggest gaps in modern cad is how we communicate design intent.
we spend hours designing parts, then communicate what actually matters through a separate drawing.
gd&t shouldn’t be an afterthought.
critical dimensions, tolerances, and manufacturing requirements should live with the geometry itself.
this is our first step towards that.
Introducing critical features:
mark features that are need specific dimensions.
mark your threads and finishes.
get a downloadable drawing.
upload your parts, mark your critical dimensions, we will make sure you get your parts RIGHT!

NEVER DFM AGAIN
they literally solved it
Today we're shipping DFM review.
we built a system that flags manufacturability issues on your part and tells you exactly how to fix it.
we let you know exactly what features we can't do in our shop -> you make the modifications -> we get you the parts QUICK!

generic dfm checkers are useful, but they only tell you whether a part is manufacturable in theory.
what matters is whether it can actually be made on a specific set of machines, with specific tooling, materials, and setups.
most engineers never interact with the machines that make their parts. this creates a massive knowledge gap between design and manufacturing.
a dfm system built around the actual capabilities of a manufacturing platform closes that gap. it tells you what won’t work, why, and exactly what needs to change.

week 3 at @ycombinator
moving into week 4 with a lot of clarity, made a lot of chips, ordered a bunch of metal, broke an end mills, built a lot of software
look out for a bunch of launches this week 👀

Wait two weeks to find out a part doesn’t work.
Then wait two more weeks to try again.
@dayumsam knows what that does to a builder.
He started in hardware.
During COVID, he switched to software because he couldn’t get parts. Slow iteration wasn’t just costing him time. It was discouraging him from building hardware.
Now he’s back, making parts for other builders.
@twentyfour_26 manufactures metal parts in San Francisco for robotics and consumer hardware startups.
But it didn’t start as a machine shop.
Sam and his co-founder @hemanthug were building software for manufacturers. Selling it was hard.
So on the first day of Founders Inc., they changed the business: instead of selling software to manufacturers, they became one and started taking orders themselves.
Their approach is deliberately focused.
Rather than trying to manufacture everything, they standardize the machine, materials, tools and workholding around a narrower set of parts.
Their software handles quoting and programming, and they run production themselves.
Upload a STEP file. The software checks whether the design fits their setup, flags anything that needs changing, and turns accepted designs into a quote and machining plan.
When the part fits and capacity allows, they can cut it the same day.
For a hardware team, that’s more than a shorter delivery time. It changes how often they can test a design, learn what’s wrong and try again.
The obvious cost of waiting is a delayed prototype.
The less obvious cost is a builder deciding to work on something else.
Sam’s building for the people who want to stay in hardware.
"Send CAD. Get metal."
