@mr.impression.3d: Moins de matière. Toujours capable de faire le travail. C’est l’objectif de l’optimisation topologique. On indique au logiciel les efforts à supporter et les points de fixation. Il cherche où garder la matière et où en retirer, selon les contraintes définies. Résultat : une pièce allégée, aux formes parfois étonnantes, que l’impression 3D peut permettre de fabriquer. Et derrière, on teste pour valider. #additivemanufacturing #3dprinting #imprimante3d #impression3d #3dprinters

Hacker :

Went from a $100 part to a $2000 part. Nice work

Engineer :

And you have now tripled the machining time

carterrsully :

The bulk still provides strength even if it doesn’t hold most of the weight

Neutros :

Manager: why did the part fail? Engineer: the computer said we didn't need the extra material :)

Lloyd33 :

and people wonder why older equipment seems to last longer

tsmith154 :

Forces in the real world are not exactly as we design. Be prepared for some unexpected forces. Even for someone using a pry bar. or a bloody hammer because they're trying to replace this part or something nearby.

MyBackYard :

I wanna see stress flow paths AFTER material reduction.

Ash :

and that folks is how you reduce the lifespan of a part by 90%

SSTB10 :

ByteNerd :

Might save a little bit of weight. Will cost a boatload more money.

Omega travels :

yeah so your telling me taking away material wouldnt then change the results of the stress test without the excess material that supports the material under stress... righttt

🇨🇦 Angry Canuck 🇨🇦 :

unless those parts are getting 3D printed that's more expensive because mills still have to remove all that material from the block. and it still gets wasted.

St.Almana :

BS, corrosion not included

leftist advocate 3 :

okay but now when it does crack it will snap clean off instead of just having a crack.

Swiss cheese :

this is super useful for things where every gram counts. F1 cars, race bikes, &c. Structural durability isn't as important. as the budget is there to replace the part more often.

franky :

Unable to withstand deformation.It will collapse like a house of cards.

aakkonst0 :

На анимации моделей нет учёта динамической нагрузки, градиента статической нагрузки и проверок на работоспособность при износе деталей. Все это не говоря про изменения в площади соединения деталей сварными швами, и сохранению значения передаваемых нагрузок от болтовых соединений при условии уменьшения возможных принимающих поверхностей от материала, все это приводит к увеличению хрупкости деталей со всеми вытекающими последствиями

TheGuyInTheCorner :

yes yes there's so much wrong with this, but it could be really cool for 3d printed parts where every gram matters. definitely has it's usecase

IONE Gamer :

выглядит ненадежно

Metafleks :

Doesn't this just add more manufacturing time? To remove material with a mill or laser table. Just leave the flange be square.

legoshart :

the stress only is in the areas where is it when you first measured and scanned it because of the "excess" material, remove that "excess" material and now your stress spots have changed

ray_ghawi :

Manufacturing cost 📈

Thrive :

I ran a little experiment with loadbearing. Removing everything that’s not under pressure changes the location and intensity of the pressure.

lonore980 :

I'm wondering if this is satire as an actually engineer

vasilepopan55 :

now do the simulation on a removed material one,you'll see the stress is much higher
