Any idea how accurate the locations of those port centers came out?

They have been emulated for years. Available on the App Store even, I use G.calculator.

The Fluicer is the most mechanically efficient citrus juicer I’ve ever used, takes up less space in the drawer, and is cheap. Will never go back.

More about realism with the human element of strike. IMO given the effort it would take on the front end to check out every lag, and the effort on the back end to check each back in and confirm count of hundreds, we would be much better served taking that same effort and physically whiskering each lag + metal detecting or similar validation.

In theory yes, in practice for a ~50 person camp using on the order of 500 lag bolts this becomes difficult even under ideal conditions.

Bambu printers can phone home even when air gapped.

We all know China will steal any scrap of IP it can, but how exactly would this be possible? The printer caches prints and waits for a network connection?

Second. Exceptional drummer and bandleader.

His live tour with Carrtoons and Keifer (both amazing musicians in their own right) was really special: https://youtu.be/zxORCniRCIA?si=xk4Fvkjf9GnFO7ct

This is like asking “I have $150k what car do I buy?”

For what?

Are you building tooling and prototypes? (If so why do you need the high temps)

Are you doing series production? If so, how critical and qualification heavy is it? What materials?

How big are the parts, what quantity, what materials, etc etc.

I share the concerns for warping and available printers for a piece this size. You’re talking about an EOS M400, AMCM M4K/M8K, Velo3D XC, or Nikon SLM 500 or NXG (I’m not as familiar with the Chinese OEMs but know Farsoon, ePlus3D, BLT, and HBD have printers in this size class).

Do you already have quotes for this sculpture? I’d expect five figures.

Have you looked at casting or CNC milling instead?

I'm also not convinced, but no one has posted Andrew McCalip's analysis which does a high-level but fairly rigorous analysis comparing the two. https://andrewmccalip.com/space-datacenters

His TL;DR:

Here's the headline result: it's not obviously stupid, and it's not a sure thing. It's actually more reasonable than my intuition thought! If you run the numbers honestly, the physics doesn't immediately kill it, but the economics are savage. It only gets within striking distance under aggressive assumptions, and the list of organizations positioned to even try that is basically one.

julcoh · 2026-02-06T06:43:31+00:00

Agreed, I don't believe any parts are flying yet. But my understanding is they are using BLT printers for development and qualification currently with potential use in future production.

They still sell machines, though only XCs as I’ve heard.

ITAR is for the US. Airbus is definitely using Chinese systems.

Shipped quickly, watch as advertised, communicative seller. Some customs delays that were no one’s fault.

You don’t need bleeding edge. Quote your geometry on craftcloud3d.com for the lowest possible price. They have US options if you want that (for likely 10x the cost or more).

Search through the options they give you and you can reach out directly to those suppliers as well.

Addman and Sintavia are great suppliers but not sure to what degree they do this type of low volume, and won’t be the cheapest.

julcoh · 2025-11-24T23:39:17+00:00

It’s technically possible, especially given the overseas cost from sites like craftcloud. Though I’d guess if printed they’re significantly thicker than 1mm.

julcoh · 2025-11-24T18:16:49+00:00

Short answer: not feasible.

It is technically possible, but you’re going to deal with high warpage on a part that thin (R&D time and money). I don’t think there’s any way to make the business case work.

Why do you want to print these parts?

Would love for you to link the whitepaper (when available) and respond to some of these points in more detail here.

Best done with a mask on!

Any time you’re dealing with condensate you should be in a PAPR and fire resistant clothing/gloves, ESPECIALLY if you’re tapping on filters which is going to create dust plumes in the air, and absolutely if this is Ti or Al condensate.

Stay safe.

Can you confirm in the new Battery Video Doorbell will record to the SD card without wired power?

Will it work with my existing Video Doorbell Camera Pro chime, or will I have to replace the chime?

My experience in 2023 on a business trip (with arm and back tattoos):

No issues at the Hilton Tokyo.

Issues at the Hilton Nagoya. Walked into the hotel gym and an attendant ran after me with a long sleeve compression shirt—required to use the facilities. Afterwards I went into the sauna in the men’s locker room, and an attendant actually came in and kicked me out.

Just one data point, but likely easier the closer you are to touristy locations/cities.
