@sendcutsend Love it 😂 Did you see the smallest one? x.com/nemimilo/statu…

Machining “The Part”: A Short Film

If you have a SEM and want to help imaging, let me know, let's try a micron version Lets make the smallest @emm0sh benchy-v2 in the world (until somebody e-beams it)

@emm0sh @jimbelosic If we can find somebody with a SEM to image it, sure

@nemimilo @jimbelosic you should see how small you can make it

@emm0sh @jimbelosic how about a 1 mm version?

@emm0sh @jimbelosic It was made with two photon lithography, I could have went far smaller towards single micron digits but properly imaging it would have been a pain 😅

@nemimilo @jimbelosic competing to see who can make the smallest is such a good idea

@humphilomath @lukeweston @jwt0625 see nature.com/articles/s4158… for example

@nemimilo @lukeweston @jwt0625 Um, I haven’t had time to visit Austria properly, but will look up the company later…

wow you can really reach feature size much smaller than wavelength with two photon polymerization (2PP) this sample is from UpNano GmbH, using a green laser at 515 nm

@samschmitz Tip stays inside when you pull the handle

I designed an MRI-safe torque wrench that can be printed in place in a single piece on a Fuse 1+. Doesn’t rely on friction so it keeps 0.6Nm after hundreds of cycles. It works great but has one MAJOR flaw—can anyone guess from the pictures?

@lukeweston @humphilomath @jwt0625 Doesn‘t scale yet*

@humphilomath @jwt0625 You’re not missing anything. Nano 3D printing with 2-photon absorption has the potential to disrupt or replace a lot of other nanofab techniques. It doesn’t scale to full wafer throughput, just like how the industry doesn’t use EBL at prod scale. But it’s such a good R&D tool.

@mechadense @jwt0625 Surely, resolution depends on the objective (+print parameters) used and therefore the speed/cost

@jwt0625 Could this be used to make reversible microclips for 300μm diameter SPM needles for automated needle exchange with a needle magazine? To not … ★ need to replace a non-cheap qPlus nc-AFM sensor ★ be doomed to the tap to fix tip hack ★ be doomed to manual needle fix out of UHV

@jwt0625 Using it everyday, has quite some advantages

@zanehengsperger How much

holy cow factory space in CA is expensive

@YunTaTsai1 Does the new AI5 chip include PWBs?

AI changes the nature of compute, thus it also changes how a chip is built.

@jwt0625 Co-packaged optics should speed this up

transceiver modules and attachment for 16 x 3.2 Tb/s

@jwt0625 How do they dissolve the resist although it has such crazy undercuts

god this looks so fun Smith2021: [High Frequency, Low Loss, Additively Manufactured Hermetic Package](imapsource.scholasticahq.com/api/v1/article…)

what the hell is this polystrata process, bruteforce additive 3d copper components and packages by layers of photolitho + plating + planarization + die attach for embedded components, and rinse & repeat..

@mbpup @jwt0625 Website available? Interested in hearing more

@nemimilo @jwt0625 novel process for micro-scale metal parts

A powerful laser lights stuff on fire, until it does not. ("cold processing" - when a fs-ps laser pulse vaporizes material faster than thermal or mechanical time scale.)

@mbpup @jwt0625 What kind

@jwt0625 nope, still working in extremely niche and wacky 3d printing however

@jwt0625 Using fs for 2pp lithography

@inventorOli Sounds like you need a better table or base for the arm, big vibrations seems like

🤖🦾 Robot arm project update. With new aluminum parts, the rigidity and repeatability are greatly improved.

Agree, from the outside it sounds like crazy…and it really is, just in a different way than you would expect The density of talent & resources is like nowhere else
