VR Sculpting to 3D Prints with Gravity Sketch ( ...and Printing Iron? )

[Music] cool hey everybody its devin here again with make anything and today we're doing some more sculpting and virtual reality so maybe you remember a few weeks back I did a video sculpting on my HTC vive when I made these little guys and that was super fun and exciting I think you guys liked it I loved doing it I'm especially excited for this one though because I'm showing you guys a brand new application called gravity sketch it's in pre-release right now so many people haven't even seen it and I think it's a pretty powerful tool for 3d modeling especially since you can output those models into files that can be 3d printed so how about we get straight into it and see what gravity sketch can do alright so here we are you can see pretty much what I'm seeing in virtual reality here we have the menu for gravity sketch it's it's interesting pretty much designed especially for VR so it took me a little bit to get used to but I made a few models so that I would not be in a total loss when I'm working on this for you guys so as you can see the first thing I'm doing here is using a surface tool that lets me draw on a flat plane so I'm just making this circular platform so that I have a flat base to stick to the build plate while I'm printing it so that's a good foundation from there I'm using this cube brush I'm like code on where you're sculpting this virtual piece of clay in gravity sketch you're basically drawing out solid forms like you're drawing on paper but in 3d so I'm using this cube brush and basically drawing out these long cube prisms I'm not exactly sure what the name of this shape is a cube noodle I guess I can call it that because I always name things funky and I really like the cube brush because it kind of combines the very geometric shape of the cube but when you draw it becomes more organic because it's using the actual motion of my arms and like how I'm drawing it out in virtual reality so I'm just trying to draw a hand here I want to do something that I couldn't really do so easily in SolidWorks so basically anything organic especially like an anatomical model like this would be very difficult to do in SolidWorks [Music] and as you can see it's very easy for me to just slowly go around move them all around and look at it from every angle and just add on to it until I get that mass that I want so I'm just going to slowly fill out the fingers now this finger right here I kind of wanted to make it interesting but I think that overhang might be a bit tricky for my printer and it doesn't really make sense maybe I'll just have that finger go straight up as well the other good thing about this software is it's not parametric like SolidWorks you can't just go ahead and like stretch out a line after you've already done it but it is non-destructive so I can undo basically as much as I want or I can select a specific part by hovering over it with my right controller with that little red sphere and then I can just take specific parts and move them around or delete them and it doesn't matter if it was the first line I drew or the last one and I really loved that about this software it makes it even easier to just work without having to worry about things too much because hey if there's something you did at the very beginning that you end up not liking you can just go grab that and get rid of it and it won't ruin the rest of your model so I'm just going over these lines a couple times to make them a little more organic and interesting so it's not just a single cube they're kind of overlapping to make this really complex shape all right starting to come together pretty quickly admit I have very little experience creating anatomical models in any medium let alone virtual reality so this might not be perfect but I think it's actually coming out pretty well all right so our hand is done and now I'm going to go down to the base and kind of add a whole bunch of cubes and make it look like this hand is shooting out of the ground or something creating some kind of dynamic explosion I'm really fascinated by creating a form that will create the feeling of motion even though it's obviously a static piece but by having these blocks kind of jutting out and every action simulates a frozen moment in time versus just a static sculpture [Music] I think the other reason I'm really drawn to this cube brush is because it reminds me of like minerals and gemstones that can have perfect cube shapes but they're still very organic and placed kind of randomly and chaotically and that's kind of what I'm trying to go for here so the awesome thing about this is I can just keep working on it until I'm happy I can add things take things away and at some point you just gotta say alright that's it I'm done so I'm pretty happy with this model and if I just save within gravity sketch it'll create a folder on my desktop with the obj file that I can convert into an STL for 3d printing later I'll show you that whole second part of the process but first I'm going to do one more sketch for you guys because it's pretty fun and I think it's cool to watch in this one I'm going to start out by turning on mirror and as you can see it turned on this grey transparent wall and that's my mirror everything I draw will be symmetrically mirrored on the other side and that's pretty cool for creating like models of living things or creatures and such because you know most animals are somewhat symmetrical I like to create a base using the mirror mode and then before I actually finish the model I'll turn it off and kind of add details on either side to make it a little imperfect because you know nothing is perfectly symmetrical but to start out this is a great way to get a nice even form so I'm making sure to fill up everything here that way I won't have these difficult to print hollow spaces inside of my form but then I'm just gonna slowly keep building up and I'm kind of just creating a head here so I'm creating a kind of stylized skull or it's maybe gonna be like some kind of tribal item I can imagine some ancestors creating these scary omens to summon spirits or something I don't know but anyways I'm just gonna keep working on that building up as you can see it's very easy to adjust and just move entire parts it's like one of my favorite things about this and I'm just gonna keep on dry make sure that I got the eyebrows there we've got the nose we've got some teeth and then I'm going to kind of fill the inside of this eyeball and start fleshing out the back of the head building up slowly making sure I don't leave too many gaps in virtual reality of course I can do pretty much whatever I want but I have to consider that I'm going to be 3d printing this so I do have to be aware of any overhangs I'm creating and make sure that this is something I'll actually be able to print out successfully so I turn off the mirroring so that I could kind of get a little more asymmetrical and natural with this hair or whatever you want to call it I'm giving it a little decoration on the back at this point I thought I was going a little overboard with the hair so I actually decided to just scrap it and kind of do it again in a different way so I was able to easily just get rid of that hair and now I can experiment some more and see what I like so I'm thinking these more chunky blocks are gonna work out better so it's not quite so crazy on top I don't want to distract from the skull itself too much some parts like this eyebrow were giving me trouble so I decided to switch to the round brush and as you can see that creates a bit of a smoother line so hey why not just go around and kind of start smoothing things out I already did my super geometric model for that hand so nothing wrong with doing some rounded parts on this one yeah so I ended up kind of changing the direction and going a bit more organic again using these round brushes and making these kind of swirly patterns I think it looks pretty cool and it also creates a more of a contrast between that geometric hair part that I have and the skull itself makes it a little more dynamic and interesting alright so make sure to save this skull and like I said saving this sketch will create an obj file and in order to do some final modifications I'm going to bring that file into meshmixer so when I bring it into meshmixer you can see that all these different strokes are different colors and that's because gravity sketch doesn't create a single model it actually keeps each stroke separate that's why I have to bring it here into meshmixer and use this make solid command and that is a super powerful tool that'll just take all those lines combine them and get rid of the whole mess of intersections and instead create a single form so I'll just play around with the settings a bit and since I have some geometric forms here I want to set the solid type to that sharp edge preserve because that will get me nice clean lines unlike these really ragged edges that you're seeing here of course you can use whatever settings you want it's fun to play around with and see what kind of different results you can get so there we go I've got a nice solid form and the next thing I just need to do is use the plane cut feature which will cut the bottom off and give me a nice flat surface to print up from so I can preview it look underneath make sure there's no holes and when I accept that boom the model is pretty much done I think that's all I have to do and it's ready to 3d print I save that STL and then the final step is to bring that file into my slicer which is simplified 3d when you're working in gravity sketch you really have no idea what the scale of the object is so I really don't worry about the size until I have it here in the slicer and I can easily scale it up and down within simplify 3d where I at least have this virtual build plate to reference the size of my model so I'll just go ahead and scale it however I like I think this is a good size and then I'll Center in my build plate and I'll make sure I have the right print settings I want to make this work I'm not really doing anything crazy with the settings here I'm just making the layer high point one millimeter so a little more high resolution than I usually go and I'll also take down the infill to 20% the preview function is pretty great because I can look up here at this super steep part and see if I think it'll print out it's definitely agree Civ and goal here that we're trying out but I think my printer can handle it so I'm gonna go ahead and send it out alright so here is my skull printing out and if you can tell it looks kind of metallic or sparkly and that's because I'm using this very special material from a company called proto pasta and it's a composite iron PLA so it is still PLA plastic but it has some little bits of iron added into it I'm using that iron composite PLA for this model in particular because I'm trying to create that look of an ancient relic and iron has the ability to rust and create a patina which is kind of a way of showing the age of an item and what's really cool about this is you can create a special rust solution apply it to this part and it should oxidize at a accelerated rate so before I add my solution I'm just going to go over this quickly with a metal brush to kind of buff out any ridges and such and now I'm going to create my own resting solution using white vinegar hydrogen peroxide and salt so I'm going to pour some of the vinegar into my glass here and about an equal amount of hydrogen peroxide as well and then finally I'll add salt until the solution is pretty saturated then I just mix it up with this brush and brush it straight onto my part and I also leave it for a few hours covered in this paper towel that is soaked in my solution because I want to get a nice good rust so while that sits in rust I want to show you guys some other models I created in gravity sketch so this one here is my first model that I actually created in gravity sketch and it was very much inspired by that gemstone look and also the desire to capture action in a static piece this was a pretty nerve-racking print because I had no idea if it would work it's got some pretty steep angles and I had to leave it overnight because it's such a large print so I am just stoked that it survived the night and came out so well [Music] here's another very similar sculptural piece I mean I just like the style so I guess I'm creating a series now [Music] [Music] all right back to my rested part here it is after a couple hours and as you can see it has turned a bit more brownish orange it's not super rusted but it definitely made a difference all right guys so for my second attempt at sculpting and virtual reality and bringing that into 3d printing I think my results today were pretty awesome gravity sketch is obviously a very powerful way of creating in virtual reality and bringing that into 3d printing I was able to make these complex sculptures relatively quickly and intuitively using virtual reality I mean I could make this stuff in SolidWorks but it would be a pain in the butt using virtual reality it was really nice I was just kind of going with the flow let me just get my ideas out there without having to plan it out as much as I would have to with some other 3d software so I'm really getting more and more confident that virtual reality is a useful tool for creating art I'm also really excited about this tribal skull thing I created using that iron composite PLA my wrestle solution obviously wasn't as powerful as some things I've seen online but it still gave it a nice aged look and maybe I'll just leave it outside and let it age on its own and see see what happens with it could be really cool oh and I should also mention that the iron PLA is somewhat magnetic so I'll have to play around with that some more at a future time and see what I can do with that material all right that was another episode of make anything for you guys I hope you enjoy it make sure to LIKE and subscribe and leave a comment it's always nice to hear from you until next time don't forget to stay inspired you

Is a 3d printer expensive?

[u/faction1337]

that was pretty fucking cool

[u/[deleted]]

That's really something. I wonder if he could he have gone finer with the brushes in VR or if it's just cube and sphere.

That shirt makes it look like he is really sweaty at the end.
