Just published my first review paper on cooperative robotic additive manufacturing, main focus was trying to capture the most recent developments in toolpath planning, motion planning, sensing and digital twins

Is it too much to ask for a $700k 13,000sqft mill from 1900 for a manufacturing startup?

This guy is getting very close to sub 1 minute benchy with a very interesting hotend design
There should really be a better quality metric which people optimize for, a really good 3 minute benchy would be much more useful

Manufacturing is 80% procedural and 20% propositional - most of it is learning by watching and doing. A 2 week training can't replace the knowledge gained from operating a machine for 20 years, especially when mistakes are costly

My submission for this is a stock loader for a race grinder, operator loads a stack of outer races which are fed to an air chuck, ground and released. I was responsible for the pneumatics, vertical loading system and the parameterized chutes for ~20 bearing sizes

It is very easy to see who has made physical objects in the real world vs digital based on how they post

Very true, I have not seen anything to convince me that your points have not been addressed. It will lower the bar for simple designs but not more complex

Recent met with someone who graduated 1 yr ahead of me at the tech HS I attended to who in the past year started a 2 man machine shop with <100k, no initial jobs (as promises had fell through) and is now making 10s of thousands a month w/ a fully tooled shop and a 2nd 5 axis coming in this month at 24 years old. This is the type of founder the US needs to reindustrialize

Why don't we have a factorio style game based on real manufacturing processes, real prices, logistics etc so we can get the masses addicted to industrialization

There is always a cost. Do we want to pay the price now while we rebuild our manufacturing base or in 5 years when China comes knocking?
tariffs will cost the average person an additional $835 a year while we rebuild american manufacturing. could be easily offset with zero federal income tax too

A fellow tech HS grad turned <100k into a profitable (10s of thousands MRR) machine shop in 1.5yrs at 24. A thread on starting a manuf. business from scratch.

Yup its in CT and practically speaking it would make more sense to get a newer building for the same cost, the idea of renovating an old mill is just too good though

Even with gloves the capability of your nervous system and your hands far exceeds that of current hardware. Give that gripper to someone who has had a stroke, has MS or other serious nervous system or hand injuries and see how well they can do basic tasks

Mechanical engineer python code which is developed just to work is some of the most painful code to debug (it is my code from undergrad)

Blueprint automation is incredibly dependent on the ability to reason about tolerances and GD&T. I do not trust LLMs to make any design choices about a single part, let alone a full assembly

This is massively different than the attitudes of how old school American companies treat their workers. When a cell is inefficient the question is usually how can we improve or replace the system, not the person.

This is not a dig at CS people, I think that how you learn to solve problems with code is different than physical problems

I can't wait for tariff season and US reindustrialization
This has been going around, let me explain as a manufacturing guy what you are seeing:
Economic 5th Generation Warfare
That is 100% what this is. The CCP subsidizes every aspect of these operations with the express intent of destroying America’s prototype and production infrastructure. If you are a US startup- why would you boot up a model shop or use your local machine shop when you can just send all your IP to China and get parts back in a week for 1/10th the cost?
If the US Government would:
- Let me buy CNC equipment for 1/4th the price
- Give me a building
- Sell me raw material for 25% the global commodity price
- Subsidize my workforce
- Offer zero repercussions for pirating the most advanced Western CAD/CAM/FAE tools
- Have zero environment, safety, employment regulations
- Offer me a postal service that did FedEx international shipping for 5% the FedEx cost
Give me all of that and you bet your ass I can build you tiny bullshit turbines for $0.75. Sounds like a nice hour long programming/setup project!
Do not be fooled by any of this- this is not Chinese engineers (who are *very* good!) competing against us- this is the Chinese government looking to put a significant percentage of America’s manufacturing base into the ground.

I can see the $4k used price, but I also don’t see anything particularly special about what they’re doing.
If you know PCB design and how to cut down on machining costs, I would imagine you could be very competitive especially with OnRobot being a Danish company which will be probably be impacted by tariffs. Their big selling point is ease of use so if you match that with 10-20% lower cost thats probably a win

Its insane to me how I have to constantly convince people that technology is good, like would you rather something take 1000 hours or 1? Its really that simple

Some PhDs are, some let you work on cool projects with other cool people you would have difficulty doing otherwise

I am well aware, I made this in undergrad. The challenge is getting something to work as simply and cheaply as possible. A spindle has few parts but is incredibly challenging and expensive to manufacture.
I hope your product succeeds. I am concerned about the challenges of design and how little people mention GD&T

I have yet to see any good robotics solution to bricklaying that looks pretty and is accessible. We should be investing in making cheaper high quality homes not concrete slop boxes

People coming from software don’t understand that the key is to make a useful tool, not just market it well.
Theres a video of Steve Jobs talking about the software being customer focused instead of being marketed, which to me seems obvious. Manufacturing success is 99% product quality and utility and 1% marketing most of the time; its really almost all connections to trust that you will deliver what you promise

When we have a base on the moon in 4 years how are we going to machine parts? Is it really feasible to ship mills to the moon?

Yes, as much as I would prefer a non-China printer they are too good to pass on atm. If you don't need one soon they have a yearly anniversary sale in the summer where everything is 20-30% off

I was just arguing with some grad students about this. People really have low bars for themselves for being able to figure things out, way too sensitive to being uncomfortable

People are often surprised how much I pay for local things vs. imported/big business. I'd easily pay 2x for higher quality locally made products if it means they'll stay in business and expand. You should put your energy towards things that you want to grow
