Printing Gaussian Splats
- deleted 3mo ago[deleted]
- relaxing 3mo agoVery cool product! And to think, in one of the many prior gaussian splatting threads someone declared there was no way anyone could build a business around the technique.
- spencerflem 3mo agoTo be fair, if they first vocalize it they could just use Sparse Voxels which is my favorite differentiable rendering technique https://github.com/NVlabs/svraster https://github.com/NVlabs/svraster
- amluto 3mo agoI find the workflow of fitting Gaussian splats and then immediately turning them into voxels to be rather surprising, too. I can imagine some performance benefits at large scale, or maybe a reduced tendency to generate certain types of artifacts, but going straight to voxels seems more straightforward.
- pizzathyme 3mo agoIncredible. I may be the only one in the dark, but until this moment I had no idea 3D printing at this high a fidelity was possible. It looks like a real bee. Last I knew, the best 3D prints still looked like hardened play dough
- Gigachad 3mo agoI do a lot of 3D printing and I had no idea either. I did some searching and this printer is as big as a work bench and likely costs around $200,000.
- arjie 3mo agoIt's different kinds of printers. That's a resin printer - pretty high-end one. I'm not getting that result on my Bambu P1S.
- stavros 3mo agoBut how does resin do colors?
- shitloadofbooks 3mo agoOne approach is to just print CMYK resin like an inkjet printer (and then cure it with UV). Do that hundreds or thousands of times and you eventually get Z height. Look up the EufyMake E1 for a consumer/prosumer version.
- Gigachad 3mo agoThe EufiMake isn't really a 3D printer though. It's more a normal printer that can do an embossed/textured print.

- jawngee 3mo agoUV Inkjet. HeyGears is releasing a prosumer full color UV inkjet resin printer this year for < $2K: https://store.heygears.com/products/heygears-g1-direct https://store.heygears.com/products/heygears-g1-direct
- wincy 3mo agoWell, to actually 3D print looks like it’s $3300, but still that’s really incredible! Seems substantially less messy than the resin printers I played around with a few years ago.

- crazygringo 3mo agoSame. This is insane, I had no idea! There's nothing I personally want to bring, but these would make AMAZING gifts, cool things for your desk/bookcase, etc. There have got to be so many interesting, educational, and cultural objects you could print like this, and the fact you can "blow up" an object like a insect is even cooler. Depending on the price, this feels like something that could take off in a big way.
- TacticalCoder 3mo agoThere s a whole spectrum between hardened play dough and the bee in TFA. A $200 printer with a 0.2 mm nozzle and proper setup (ironing calibration etc.) is already capable of making 3D prototype prints with details that look professional (e.g. highly legible tiny fonts). An example would be the multicolor articulated dragons that are flooding flea markets and garage sales around the world : when printed properly they are highly detailed and looked mass produced. Unsuspecting parents buy those for their kids and have zero idea these were 3D printed on $200 printers. The 3D printing world progressed a huge lot in a few years, which is what prompted me to buy one. It progressed so much it s basically solved.
- terabytest 3mo agoWhat is the 3d printing technique being used here? I can’t intuitively recognize it.
- JonathonW 3mo agoResin, on one of these big expensive Stratasys machines: https://www.stratasys.com/en/3d-printers/printer-catalog/polyjet/j8-series-printers/j850-prime-3d-printer/ https://www.stratasys.com/en/3d-printers/printer-catalog/pol...
- diabllicseagull 3mo agoso they buy and operate the machine, the customer brings the splat. is this just a print lab?
- promiseofbeans 3mo agoLooks like it. Plus it looks like they’re closer to a traditional screen sprinting shop in that they just take a file and will work with you manually tweak and adjust things to look good, rather than just printing a file straight away
- Lerc 3mo agoI remember seeing a 3d printer that was essentially a 2d printer which printed the surface and cut the outline and then laminated the sheets together which depending on the paper used would get you a block of something between mdf and plywood with high surface detail imagery. I would imagine much the same approach could be done by laminating clear plastic sheets if you can maintain the transparencey without bubbles. It would get you modern colour printer resolution in two dimensions and sheet thickness in the other. It wouldn't surprise me if some smart cookie could make a resin printer with a resin that sets in a state reflecting different wavelengths depending on how you zap it. That's a problem left for the reader. You could easily release pigment into resin just before it gets hardened, but getting the right pigment to the right place would be hard, A print head zapping back and forth inside the liquid doesn't sound like it would be viable. Printing in resin bottom to top part could allow a colour print head to fly over the surface printing a pigment layer then squirting the next layer of resin on top, zap and repeat.
- pants2 3mo agoThis is insanely cool. My wallet is ready.
- warumdarum 3mo agoFantastic work!
- vicentwu 3mo agoI want buy one.
- smusamashah 3mo agoThis is the splat https://superspl.at/scene/3ae6a716 https://superspl.at/scene/3ae6a716
- loclol101 3mo agoDefinitely ready to try this. Some scifi stuff
- KeplerBoy 3mo agoHow much are the prints approximately? Can't see a price anywhere.
- thenthenthen 3mo agoNot sure, but this will be cheap soon and invading trinket shops everywhere for sure!
- KeplerBoy 3mo agoSure beats flexy dragons, so I'm all for it.
- thenthenthen 3mo agoYou know exactly what I was hinting at haha
- jibal 3mo ago$143 according to a comment on the page.
- circuit10 3mo agoTrying a bunch of sizes in their studio tool (all cubes to make it easier): 5mm x 5mm x 5mm (smallest I can select): $32.58 10mm x 10mm x 10mm: $36.58 20mm x 20mm x 20mm: $82.86 30mm x 30mm x 30mm: $143.60 50mm x 50mm x 50mm: $509.14 100mm x 100mm x 100mm: $3,028.58 150mm x 150mm x 150mm: $9,618.86 195mm x 195mm x 195mm: $20,641.32 (it says it's an estimate excluding tax and shipping)
- motoroco 3mo agoIt does not include shipping. I paid an extra $30 for shipping a 40mm cube. It’s the only reason I didn’t comment initially in support of an otherwise cool service
- GL26 3mo agoInteresting how they voxelate the splat to print it. I am sure there are more efficient algorithms that allow you to make a mesh which then gets sliced before printing
- corysama 3mo agoBut, if you made a mesh you wouldn’t be able to represent fuzzy objects. That’s one of the major advantages of both splats and this printing technique.
- Arwill 3mo agoI am wondering if it would be possible to print a splat similarly as it is shown on the screen, so not voxelized, but like a hologram with overlapping transparent gaussians. It looks like the model from the outside at the given angle, but the inside is nothing like model itself.
- pennomi 3mo agoResin printers like this use UV pixels to cure the material instead of extrusion nozzles to trace the perimeter. Voxels are the natural format for resin.
- simonjgreen 3mo agoOverview of the printer used: https://youtu.be/T6sxVtViX-k https://youtu.be/T6sxVtViX-k
- lnenad 3mo agoWow, truly amazing that you can print a high fidelity Snickers bar.
- noduerme 3mo agoThis is genuinely fucking cool. I don't think I've ever seen a 3d printing implementation like this before. I'm not a big fan of splats as a modeling method, but for something like this it's fantastic.
- a_c 3mo agoI can already see myself hoarding all the prints
- tugdual 3mo agoAbsolutely incredible
- stevep98 3mo agoOnce in a while I get inspired by a post on HN, but I know I don't have the energy to follow it through. Here's my idea for anyone who thinks they can do something with it: Imagine you are holding in your hand a small glassy sphere. Initially it looks like random dots inside, but as you play with it in your hands, you get glimpses of images of loved ones. To implement this, select a bunch of photos of people, generate pseudo-3d models of their faces with your AI of choice. Position them around a sphere in a 3D modelling software, and generate a whole bunch of renderings all around the scene. Now, feed those renderings into gaussian splat software. The resulting 3D gaussian splat should include relatively high fidelity when the viewer is aligned with the supplied iamges, but more stochastic nonsense when misaligned. This should contribute to the feeling of being able to 'find' images while rotating the sphere around.
- lairv 3mo agoNot exactly what you describe but this project [0] did it with cubes. The cube is filled with splats. Each face reveals a different picture when viewed from a perpendicular angle [0] https://www.3dpoint.art/ https://www.3dpoint.art/
- bobson381 3mo agoif you allowed for some slippage in precision, how many images could you fit in that are recognizable from various angles, with ~acceptable~ resolution? Sounds fun.
- PashaGo 3mo agoWhy it's called Gaussian?
- corysama 3mo agoThe original paper that kicked off the movement a few years ago used Gaussian blobs because gaussians are differentiable and the tech to analyze a scene requires the tech used for rendering to be differentiable. https://learnopencv.com/3d-gaussian-splatting/ https://learnopencv.com/3d-gaussian-splatting/
