![Noob To Max With DRAGON REWORK In Blox Fruits [FULL MOVIE]](http://i.ytimg.com/vi/LnBMOinoOvA/mqdefault.jpg)
LITERALLY wife just walked into my office while on the video you talked about buying a blender, and she said "So I guess I will be expecting a Blender and an Oven in this room" and walked away!
@Unclejessy. 😆😆😆 I see what you did there adding a period after the name...
maybe get her a spa day or something "just because I love you babe"
They like that, buys you a lot of leeway for a couple months.
Why are they like this
3D print her a spa!!
The first thing that came to my mind when you pulled out the first mold. I want to make some D&D dice out of my scraps
I know right?!
Definitely this.
Right on! Making complex molds is a blast. I've been over-molding things into my designs. Its a blast!
If the filament has a comfortable margin between melt and burn temps. If you melt them first and then pour them into a mold, you might be able to get a better finish. and make sure to mix in some plastic with a lower melting temp or lower viscosity to have better flow, that will also help getting those bubbles out doing it the normal way
How do you pour it. I tried melting and never gets liquid enough to pour it in molds.
@@roll4stealth671 The plastic type is the most important factor. I dont know which filament has the best flow
I hate to throw away PLA waste from supports and fail prints. I've been researching on how I could transform it back to a recycled filament, but it is just too complicated. That's a great way to give them a purpose! Thanks for the video!
Suggestion: When blending, wear a mask. Especially if you make a living 3D printing, and therefore have a lot of waste that you are recycling. The fine particles that are created while blending, and that you may not realize you are breathing in, will eventually catch up to you if you don't wear the appropriate safety gear for your eyes and lungs. It is also advisable that you melt your waste in a well ventilated room, along with blending.
I got such a bad migraine after I did this
I definitely wouldn't melt anything in an oven that you use for food. Good ventilation while melting is most likely a good idea. Probably set up in your garage, barn, or outdoor shed.
Something you could test out: grind up your leftovers as tiny as possible. Then mix a batch of resin. Add the plastic grindings to the resin. Pour into a mold of your choice.
Wonderful idea, I have been using grey PLA+ like crazy and I have so many saved supports. Be fun to get some simple props with the waste, or at least make it usable for test painting on the smaller model designs.
This is what I like about the community, someone tries a new idea, and gets great result, and shares it, the community goes forward with a new tool in our box of trick...I tried to buy the skull mold today, and now they are sold out...luck I have a spare silicon skull ice cube mold to play with....and plenty of glitter to mix in....
That's a great idea, printing your own molds for this. Definitely going to give this a try.
This is gonna be a fun series to follow. Looking forward to more molds and master molds.
Just had my first melt. Thank you for inspiration!
@Uncle Jessy If you were going to do a large item with alot of void area inside, you could always partial fill, wad up some aluminum foil to fill the space and then fill up the ground up filament around it...kinda like what you do when you're making an armature for clay sculptures!!!😁👍🏻
PS--would cut down on the bake time as the PLA would be at the exterior of the object.
That right there is a fantastic suggestion! Will be giving that a try
Smooth on make some high temp silicone you might get better mileage out of
Oh man! Okay, I gotta go look into that! Thanks!
Oh maaan I'm gonna try this with some of my old silicone molds!
For the blending process... Would it be wise to wear a respirator? Microplastics and such.. other than that, cool as heck! I gotta try this one myself!
We ingest about a credit card size of micro plastics a week lol you will be fine as long as your doing with in a open area and not dumping it right after the blender is finished. I would let it sit for about a minute so anything small flying around is now settled.
But a credit card size is too much. We ingest too much to start with. It's like saying you get a cigarette if second hand smoke a day so another cigarette will be fine.
You need some high temperature silicone if you are going to be placing it in the oven so you wont have to worry about any problems. Smooth on makes high temperature silicones for mold making.
Very cool I love how that big skull came out.
I have a bunch of silicone molds because I used to do resin casting, gonna test this NOW! thanks
Just how viscous can PLA become? would it be possible to melt everything in a pot like you would gold or silver and then pour into a mould?
I'm thinking of starting up my own etsy shop for 3d prints in the near future, and this seems like a great way to use any scraps/failed prints from printing products. Thanks for another great video!
100% and apparently they sell fairly well also!
@@UncleJessy could you also try using a 3d pen and injecting material into a silicon mold that way rather than just using scraps? Might make for an interesting video
@@zzace00 do 3d pens get enough flow to fill up an injection mold? Last I saw they only lightly extrude, and at a temperature slightly lower than a printer, but it would be interesting to try
this is so cool I was just throwing scraps away when I could be doing this!!!
Dude, this is pretty bad ass! loving it!
This was a fun one. Part 2 coming soon 🌭
These kind of videos are fun!
Are you doing a review of simplify 3D v5? I think you are one of the few 3D printing RUclipsrs (I follow) that still actually uses it, and I'm interested to see what you think of the changes.
What if you melt the filament and then pour it?
Try mold release next time also when you put more filament in press down on the melted mass to rid it of air bubbles 🎉
Nice topic, I would know more about it. What’s your experience, which silicon mixture you use, how thick are the walls etc. .
cant you use the same stuff they use to make spru glue, people use stuff to turn sprues into a glue i cant remember exactly what it is its in nail polish remover it melts the plasyic down
try using dice molds i think that would be such an amazing way to use left overs and amazing look for dice
when you go to add more PLA I'd give the mold a few taps on the side or maybe drop it from a low height a few times to get rid of some of the bubbles and voids if you were trying to get an even smoother surface.
Jessy, try silicone mold release, I been playing around 3d prints and molds. but im not sure what type of mold release you should use,, there is a few different types
Yeah i have two! For sure using them in the 2nd video for my 3D Prints + silicone for the release... works extremely well
Another option that would work well is to take the ground up pieces and mix them up with casting resin before pouring into the molds. That way you don't have to actually melt the plastic.
Would work if they're ground to a fine level and then added almost like glitter, but can be not as fine as glitter of course
I used an Ultrabase print bed, arranged scrap PLA filament bits to make a nice pattern; in my minds eyes, I was making a collage.
I popped the thing into an oven, baked it at around 180C until the material 'slumped' into one big thing.
As it cooled, I heard popping and cracking noises, and finally a very loud BANG as the glass under the PLA exploded!
Did you know that cooling PLA can strip the black surface and glass off of Ultrabase?
I now have a print-bed missing about 1/3 of its surface, to a depth of 1-2 mm!
Ultrabase and PLA will permanently fuse at PLA melting temps.
I am looking forward to seeing more expanded videos from you. In case you didn't know, if you want to make a mold with your resin printer you will need to either use a Tin based mold mix or use Inhibit X to coat the resin before molding with a Platinum mix.
Aha is that right? It's a good tip, I didn't know the resin for printers had that issue. Most cheap plasticines also suffer from silicone curing inhibition.
@@MaximilianonMars Yeah, unfortunately. You need an inhibitor of some type, tin-based, or use an older print to mold. I don't have any to test that last one but supposedly small prints can take up to 6 months to degas enough to use platinum-based.
I have heard of a few types of specialty printable resin that are okay to use on their own, but none I can name off hand.
Do you think a simple clear coat over a resin print would work?
@@Thanos88888 It is possible, I know people make cosplay props, for example, use spray cans and cover the prop before molding. For both FDM and Resin. That is essentially what Inhibit X does.
But, it also depends on how much detail you want. Each layer adds thickness to the model and can settle in recesses making them less defined, so if it is something very small and fine I would be careful. " TheCrafsMan " has several good videos on this.
The perfect use for failed prints! Nice work!
or all them benchys haha
Looks like an acid trip and a half! I love it!
Great idea's and that skull, cool and creepy as hell at the same time!
Yay! no more trashing "excess" filament. Thanks Kuya Jessy
thank you for this it's a real cool idea for converting waste pla in to more things
I have tried this yet but I've been saving my scraps to do it in the future. I've seen people using griddles or panini presses to make flat things like coasters or pendants.
Build your own vacuum chamber (it’s fairly easy) and you can pump out the bubbles. May need to keep it on a hot plate inside while removing the bubbles.
Wicked idea. Love it!
Very well done Sir. The skull is such a recognizable shape that the eye forgives those many bubbles, and it's a cool 300g gadget if i got ounces right. Pretty much a self defense weapon! :)
I'd suggest to find a way (I haven't imagined yet) to pull air out of the mixture. Idk if taking the mold out of the oven to pull it in a vacuum chamber at every melt after you add material, is feasible. The vacuum insulates a lot and the molten pla should not exchange so much heat to cristallize in the time you take it outta oven and pull vacuum to it, but I haven't tried, so... I'm watching you do it for us! :)
Ideally the vacuum chamber and the oven should be the same enclosure.
Or better, but complicated, could be trying to set up a rudimental injection system, or somehow pour in the mold already molten pla.
Yes!!! Looking forward to part 2
The algorithm brought me here. Man my first thought is "where can I buy Gridfinity silicon molds?".
I do wonder if you could use a cheaper and especially more space-efficient way than using a blender. While a second-hand blender might not be super expensive, it also takes up a lot of space, which is not practical for a hobbyist with limited space like myself. I saw someone using a drill and a specially made jig to transform filament into pellets, but I wonder if you could do something similar that'd accept random sized plastic.
As for the over, unfortuantely I guess there's no way around the space issue, gotta buy the smallest cheapest used oven you can find.
Starting 3d printing brings you down the rabbit hole of just doing more stuff.
I'd say the silicon mold started to burn from being too close to the elements in the oven as opposed to the general heat. A bigger oven and putting it on a lower shelf would probably solve that issue.
They sell mold release spray to extend the life of the molds.
Another thing you could do is melt the filament before you put it in the molds but you way looks cool because of all the colors
Collecting these PLA chunks sorted by color, I'm still planning to try and re-melt them to produce some recycled filament one day. More than likely terrible quality, cloggy, uneven thickness, totally unusable stuff, but who knows. Still sounds like a classy way to waste time, money and precious energy on a hopelessly challenging project. Until then, it's quite useful for welding larger parts together where it's suitable and out of sight.
Great Idea, I also seen the same thing on TikTok. Good use of scraps.
YEP! Thats exactly where I was seeing it as well!
On the side of safety and in my opinion, I would like to state that this temp or those baking temps are too low and at that temp, You're creating a toxic gas. Make sure to wear a respirator as well.
@zaxdesignz8698 Do you have any recommendations on handling temps here? I am considering this idea at some point since there aren’t many services with good recycling resources for 3D printed stuff.
I’d recommend getting an electric grain mill and not a blender. The blenders tend to brake fairly quickly, whereas the grain mill will hold up better
Love this. Recycling without having to build an expensive infrastructure to do it!!
You should use some kind of crusible to melt the platic in first, and then pour it into the mold. it would probably be safer. but good way to reuse old scrap piece!
I actually have a tub for all my printing waste just sitting waiting for me to reuse it somehow. I might do this with some. I make a lot of large prints so tons of support material
This would in my opninion be better for resin waste. The molds would hold out much longer since the temperature would not nearly be as high. All you would do is chop it up like with the FDM and then use ether clear uv resin if the walls are thin enough and transmit uv light or epoxy. meaning you should get more uses out of it. Next low and slow is the way to go if you want your molds to survive. Silicone molds usually start smoking at 365-370 unless it's specifically a high temp silicone luckily most PLAs melt at about 355 so that lower temperature while taking a lot of time will keep the molds at a better temp and therefore decrease the rate of degredation of the mold
Might be able to use some resin to fill in the holes and give it a more polished look.
You could probably melt down a while baking tray at once to liquid and pour that into a mold.
have a merry christmas & happy New Year uncle jessy
Merry Xmas!!
I put all my failed prints, purges, and supports into bags, that way when I get a filament maker, I can reuse my waste.
The Salvation Army are another famous used appliance stores would be a good place to get a blender like that or you could always go garage sailing. Sounds like an interesting project
Just made my skull. Lol love it. Trashed my blender but it’s so cool
Not quite what I was planning to do but this is a good second option.
How about printing a mold of a wall, fill it and then spray paint. Rince and repeat to end up with modular walls that can be attached together. That seems like a good idea to me to end up with no waste at all and with extra imperfections that will make it look uneven which is perfect for caves for example.
Do you think it would make sense to melt down the filament chips in a glass (Pyrex) cup first, then pouring the goop into a silicone mold? I really like this solution to 'recycling' filament scraps.
Would you recommend I do this outside? Does it smell? Or am I okay to do it in my craft room?
My big question is, can we find an easy way to melt these scraps down into a format that will let us use the bottle > filament method and create new filament with them? I'm thinking melt them into very thin sheets that are bendable and then cutting them into strips.
I mean, even just melting them down into sheets of different thicknesses could be useful for other kinds of projects.
Great video! I wonder if it might be easier to melt the scraps in a pan and then pour it into the molds after it liquifies.
YAY!!! I made it onto the video this time WOOT
why not melt the plastic in some sort of pot like a double boiler or something similar to melting metal then just pour into the molds and let it kool, I suppose with that much plastic you would have to deal with a lot shrinkage and warping, however at least you won't melt your molds and you can use a mold release that way and you wear your molds out as quick.
Cuz it would be like some thick gooey that would be hard to pour
@willburito makes sense
Try using some mold release to get them to come out easier.
The first part gives me hard 'Will it Blend' vibes 😄PLA smoke. Don't breathe this
I recommend using Mold Release Spray. It would make your molds last longer.
Given he's using temperatures that break down silicone in the first place, I feel like that's probably not a big factor.
You should do some strength testing to see how strong this gets once melted down. Not going to be ideal strength of the original material but stronger than a 3D printed model for sure
Could you melt the scraps in a glass measuring jug (one suitable for an oven) and then pour in the mould?
Just made my first silicone mould from a 3d print, definitely could have been better and probably should have started with a simpler print.. plus if you're gonna use the Lego bricks that come with the sets, word to the wise, tape them up! Lost most of it first time trying 😢 Made a few candles now but after watching this thought could make a copy with all the waste filament I'd been collecting, nice one 👍
Would you need the blender for purged filament with multicolor prints?
I’ve been looking for an oven safe mould all I can see is the epoxy ones, it’s not clear if they’re over safe or not lol
what about melting the waste in a cast iron pot and then pour into the silicone mold?
pretty cool, i think everyone is trying to figure out what tondo with the mounds of pla waste . there should a free drop at staples or something 😂
Candy/choc moulds as re rhe way to go smaller and easy to fill
This is great wow nice idea
Got my max on order ;-) life size ironman helmet mold incoming lol
I do something like this to make 2x4 boards for another project I am doing. :)
Can you melt the plastic first and then pour into the mold?
i have two 20kg buckets of filament scraps waiting to be recycled, im going to try this out
Maybe try pre-melting the filaments?
That way you can pour the liquid plastic in the mold, for better results?
I'm imagining doing it like people who do soft fishing baits (like Worlds Worst fishing), if possible. Could be worth a re-visit IMO :D
..... hmmm...... This combined with a little flurish with a 3D pen looks like a great filler for stock. I do love this because I've honestly have been reluctant to print like crazy due to the waste. This would help
👍🏽 I might try this
I'd suggest checking out the local thrift/2nd hand store for a used blender.
Ok, i've been holding onto my scraps (able to recycle some), but i've been mulling over how to shred my prints up enough to melt down . . . completely forgot about cheap blenders.
Do you think it would also be viable to use a heat gun to heat the moulds instead of baking them?
i also thought of a source pan....
I saw a video recently for a filament machine that takes the scrap, feeds it through a hopper, melts it, and creates new filament with the scraps, wondering if you've looked into them and if the cost of the machine is worth paying to recover the waste?
nope
you take a about 10 tons of wastage or 10 years to break even :P
Great Idea!!
This is a very good idea
Yeah a pretty fun project
I so want to do this! I have a large box full of failed prints and such that I have been saving for future recycling, and this might be the way to go. I would need a big grinder for it though, one of those more industrial looking grinders. Might have to start saving up
Cool, thanks !
How did the blender hold up? My wife is starting to dislike how much wasted plastic I go through. I’d love to be able to recycle it into something somewhat useful.
I saw a cnc kitchen episode where he sourced his own plastic shredder and assembled it. It was expensive but he was able to use it with a direct drive hotend where it had a spot to pour in ground up pla.
Actually I found that blender was unnecessary. I even put the whole failed prints, and they melted successfully. So unless you're making something tiny, don't bother
cool though always remember that to do this sort of thing outside where you can see it and if your working outside don't do this in the rain
Good video, i never sorted out my bambu poop. So its all mixed PLA and PETG. Did your (print)poop contain petg as well? Im afraid my skull would crack from petg not binding well to the PLA.
Hope to get your opinion, keep up the good work
Why not melt first then pore into the mold. Probably help prevent those air pockets and save the mold
This is exactly what a guy has been doing on TikTok for a long time now. Same molds and mica powder ideas too. If I find his name I’ll add it on here. He has full detailed instructions from the shredding to the melting
Did you ever find his name?
Question. Is it possible/safe to melt scrap PLA to fill in gaps or holes on a model?
If we could melt resin we could do so much
It says sold out. I have been trying to get a 3D printer for months and when I did finally order one it never came. Can you please tell me where I can get this printer or one like it?
Nice! Now we just need to figure out how to recycle the silicone molds 🤔
