Foil Madness
« on: November 07, 2022, 04:57:21 AM »
Hi guys,

I have been geeking out with a new VR headset (Quest Pro) and I am learning Gravity Sketch (free app).  I am a beginner with GS, just through the tutorial, but it is so cool.  You can freely create and manipulate objects in your real world environment.  Finished files can be sent on to manufacturing, 3D printing, mold making, etc.

I downloaded a foil section to play with from one of the thousands available online.  Imported the image to GS, Traced it, duplicated it and surfaced it (and then detached the surface).  Each section can be morphed, as can the whole.  It can be sliced, or cut into for attachments, hardware etc. 

These new headsets allow you to work in a variety of virtual spaces (grey loft in images) or in your real world environment.  You can switch back and forth as desired.  Manipulating a virtual object freely in your real world environment is shockingly cool (or maybe that's just me? :) ).  Oh, and you can collaborate in real time with others anywhere in the world and switch off model control, etc.  Spectacular!

Man is this addicting.  Learned some about axis and scale control, accurate measurement, added some sweep, progressively reduced the dims going outward, dipped and rounded the wingtips a bit and added some tip flare.  I kept the original section, just reduced, until the last few inches.  Couple of different textures (neither good) applied. 

I am also seeing a much easier way to do this that should allow for 15 minutes all in.

Here is a video i made this morning that may give a better idea of how sweet this tech is.  Amazing to me (still) that you can do this kind of thing and record live screen capture on device, cord free, using essentially a cell phone processor.  Things are getting wild.  What a great way to communicate product ideas, collaborate or brainstorm concepts.

Wild shit. Mine should be here on Monday. I have my trusty Prusa printer almost back in service. By the way, if you ever decide you want a 3D printer the best I've seen is Bambu Labs. I did a Kickstarter thing and got one reasonably cheap. I thought the tech sounded good but didn't expect much. It's definitely next level by every measure. I'm waiting for a hardened steel nozzle so I can print carbon-filled polycarbonate. I've done a bit of it for my Faux Drives and it's almost like aluminum in terms of strength, though I'm still shedding parts from my folding prop if I give it full throttle. "So don't give it full throttle, Bill"  "What's the fun in that??"

That Bambu printer looks amazing.  Have you tried making any molds using it?  That looks really interesting for short run carbon layup stuff.  Can your Bambu machine be upgraded to the high temp parts or is it a new machine?  I will be happy to buy in to either.

It has high-temperature heads to start with. I bought the hardened printheads for printing abrasive materials like carbon-reinforced polycarbonate. I haven't done mols with this printer, but I've made a mold for doing carbon forging. A messy process, but it made a nice part.

I am very interested in all of that.  Looks like reasonably high quality small parts could be direct printed or really nice parts (small and larger) could be done through a mold process.

Looks like you could direct print some suitably strong parts with your new capabilities.  Is it right that this machine (Bambu Carbon)  is $1,500.00?

Stoked to see your machine in the spring.  Let me know when you get your Quest Pro.

Yup, 1500 unless you want to auto-switch filaments, which I have no interest in but carseat would love. I got mine for quite a bit less on Kickstarter. Bambu sold 6000 machines in their KS project. They're just now digging out of it and about ready to sell to non-KS.

That Easy Composites guy is flat-out evil. I watch all his videos and try a lot of the stuff. Its the source of my fascination with forged carbon. Hugely talented guy, but what a time sink. My first project when I get back will be a carbon/kevlar bash plate for my KTM 390 Adv bike. I'm hugely tempted to do it in forged carbon, but it would probably turn my entire shop into a sticky mess. Find his video on doing a sled for an artic pole attempt using infusion in molds. My head was spinning with ideas for days. But anyone who has done infusion knows that you throw away at least two trashcans worth of consumables for every part you make. With my clumsiness and distracted approach to everything, it's more like five trashcans.

This video is even more seductive for anyone who has a 3D printer and wants to make stronger parts. I probably have 200 hours into making this work. It's probably how I will make my bash plate. 3D scan the bottom of the bike, turn the scan into four parts and trim it up. 3D print and fit together with pins. Bag in the Carbon and Kevlar. Toss the whole thing away and try again. It's also how I plan to rework my pseudo foil drive project using the hollow board Mark gave me. I'll rip out a few days worth of work to do it. Yay. https://www.youtube.com/watch?v=4ND2WtEZatY

Yes!  I got sucked into those videos as well.  Made me think I could do it on the kitchen counter in a clean shirt, sipping on a hoity toity.  Have you tried that oven bake only prepreg?  I will be ready to play by spring...if I can hold off that long.  Is it a bad sign that Google is now returning results for small prepreg autoclave?  I thought so.  $1500 is actually a little scary for all the Bambu needs to do but, the reviews are great and yeah, Carson will freak.  He has a Bearded Dragon coming for his B day, prenamed, Fierce Pierce, so we can build some colorful habitat toys that may not even be that toxic.  Oh, the places you'll go...

PLA is your friend indoors. The fumes take a lot longer to kill you than PET, ABS, or Polycarbonate.

As I said, that guy is evil. I started building my own autoclave using a 250 gallon propane tank and only managed to stop myself when I realized I'd never used prepreg and probably wasn't going to. I know the quality of my work would ratchet up mucho levels if I had monogrammed shirts. I'm going for it, I'm sketching up logos for Marblehead Motowerks as we speak (Diane named the shop Marblehead since it was a marble cutting biz before I bought the building and some sideways reference to the density of my Cranium).

I made the mistake of downloading Bambu Studio.  Man is that cool!  I had to preorder, but at least for the moment they are saying December.  I don't know anything about 3D printing so tons to learn, but it accepted my obj file straight from Gravity Sketch which is crazy cool.  Straight from VR to 3D printer.  Mind blowing.  Print area is too small for this test file at full scale but it looks like cuts are pretty straight forward which could be sweet for glue up reverse molds.

I figured out a few nice ways to do recessed attachment points with any dimensions and shape in Gravity Sketch with sub millimeter measurements so that is nice.  I made some progress on a split block mold but I am guessing there is a much better way or  an intermediate app that will automate that.

While you're flinging money around willy nilly take a look at Revopoint. I think I have the mini in Hood River. I bought the original to play with and then realized my brother could make more use of it, so I sent it to him. Then later I got seduced by a Kickstarter project (I have to quit doing that) and bought whatever they were offering. It's sitting tanned, rested, and ready--unused at the shop, but diving into this meta stuff it's certain that won't be getting dusty once I get back. It's 3D scanning that can go straight to print or be edited and restructured to suit, along with the software to manipulate the heck out of it. My first project when I get back will be to scan the bottom of my dirt bike so I can 3D print a mold for laying up a carbon/kevlar bash plate. Combining that capability with the meta gravity manipulation and the Bambu printer has me considering an early return to Hood River. Just too fucking exciting.

The easy composite video on making direct printer 3D molds shows how to print large molds in multiple pieces. It's generally easier to get complex shapes out of molds if they are multi-piece anyway. Looking at the combination of these three technologies to make forged carbon molds to build wings is just more exciting than I can take. I've got all the stuff at the shop to vacuum bag carbon, but building molds is always the stopper. This could easily be the solution.

I am getting Willy Nilly monogrammed on my shirts now.  How do we not have this suck and bake oven?  https://www.easycomposites.co.uk/ov301-precision-curing-oven .  Thing is Brilliant and almost 1.1 Meter internal.  With a little angle, that will fit any parts we would do.  That autoclave free prepreg process looks incredible...and tidy.  It may be simplest to to use a glued up multipart print as the (infilled/semi hollow) carbon core and laminate prepreg on top of that??  That sounds slick.  You could maybe even use longer stock carbon stiffening rods at full length if needed.  I don't know if any of that works but it seems cool.

Tidy is absolutely my primary goal. Ovens are kind of easy, autoclaves in the composite sense generally get pressurized, sometimes a lot. That's a pretty little thing but it's not an autoclave. Still, that's very cool. and has a lot more capacity than a home oven. 1800 bucks, not bad.

I love the idea of doing hollow wings with a lattice that's 3d printed as the core. I was talking with Kane about that last year. It could easily be printed in three parts. and then glassed and carboned to make the usable wing. Of course, it probably makes more sense to do something like 20% infill with a strong pattern like rotating polygons and just glue the parts together and glass. The first few layers would have to be lightly bagged or it would squish up like a plastic water bottle. The mind boggles.
