This video was made ahead of the application for the James Dyson Award. A Big thank you to everyone who supported this project along the last 6 years. A special thank you to my friend Benni who ran this project with me until Summer of 2021. It is nice to see all of it come together in this video and I hope this project can create an impact. Thank you for watching!
For those of you who know the movie Interstellar also get the name reference. TARS is my favorite robot and always helped the astronauts when hard work needed to be done. This is sort of the same what this machine does to the user when it comes to recycling plastic waste. Sort of ;)

What a fantastic project! it is both aesthetically good to look at and functions really well! The price point could be a sticking point as well as getting the molds. Have you thought about the mold supply chain? You need to make the design process and manufacturing process easy for the general public. Perhaps a partnership with Makera that makes the Carvera desktop CNC. That machine would be able to make the molds/dies for your machine. Alos think about targeting universities and technical collage's as buyers of your product. They could actually teach the whole process from designing the mold/die's through to the finished product.

There is not a word in the film about the basic parameters of the injection process. How do you control the charge back pressure, dosing speed and stroke, injection speed and pressure, switching point to pressure hold, mold clamping force, cooling time and mold temperature? Building an injection machine is less than half the way to achieving a repeatable process. The cost of building an injection mold often exceeds the cost of purchasing an injection machine with peripherals.

This is extremely cool, but unfortunately the issue of microplastics make it so that most plastic types do more damage the longer they stay in circulation, as they continually shed damaging microparticles. This tech is critical, but needs to be accompanied with alternatives to a lot of these damaging polymers.

Great idea and beautifully executed, my main issue with injection-molding tho is the mold itself being expensive to produce. I was to produce this machine i would sell it at a loss and make a profit from making and selling the molds for it. Its in the molds the money can be made.

@trevormatthews3996 4 күн бұрын

Thats not entirely true, injection molding presses can cost much more than the tooling itself. Given the small platen size, the mold itself would basically be two blocks of aluminum to form the cavity and the core side. I build plastic injection/compression molds and have worked in presses for alot of major companies. Sometimes you can make more money off of the press and the components due to things constantly needing maintenance . Such as if you blow a heater wire, burn out a thermocouple, need new ball screws, ect. But it is really sweet to see such a small press for at home use. If youre ever looking for a company to machine new tooling for you @ManuelMaeder contact Franchino Mold and engineering

@karlsparmann1881 4 күн бұрын

@@trevormatthews3996 Yes but for a tabletop machine i guess it will be serviced by the owner and i'm not saying that the machine should be cheaper than a single mold but most people would probably buy multiple molds. So by selling the machine for a lower price (not as cheap as a single mold) a person has already invested in the produkt and dus is more likely to buy molds for it. So if you make the machine more accessible more people will buy molds. Now i don't know the exakt price for a single mold of that size maybe you could enlighten me?

@EXOgreenMC 4 күн бұрын

Something to also consider, you can 3D print injection molds too. Now you probably never want to try this with FDM (hot plastic in a thermo plastic is probably not a great idea, before layer lines), but there are resin printers out there that have specific engineering grade resins for injection molding. Specifically FormLabs has some high temp resin materials for low-volume runs (I think about 500) that would be perfect for this machine. I haven't done any research if there are other high temp resins for the cheep DLP printers out there, but I imagine that could be the case. Now not only are your low volume molds cheep, you can test molds before having one milled from aluminum.

@NutzNatz 22 сағат бұрын

This really looks cool! I am not shure about the „recyceling“ as it is just a injection molding machine and the parts you produce seem to me more like downcyceling. But the machine is really impressive! Still the parts show obviously the low injection pressure of the system and uneven viscosity of the plastic i. e. too short heating. But if you improve those, you got a money printer there. that could add to fast, cheap prototyping as 3D printers did. Concerning the recyceling, yes shredded bits make sense for cost, but are aweful for process stability, a mess when handeled, harder to control. Thats why pellets are used, even tho they are more expensive then loose shredded bits. May I ask your background? looks to me like you studied mechanical engineering.

Putting on my 'constructive criticism' hat for a bit here: while I like the idea, and this looks a lot better than the Precious Plastic designs (although, will this be open-source?), I feel like "low-cost" is a bit of an incomplete statement here - the two parts of a small-scale recycling setup that are typically the expensive ones are the shredder (due to the steel shredding wheels) and the production of the molds (due to the need for accurate machining). The former is not included in this machine (how does mixed waste turn into sorted and shredder flakes without transport?), and the latter is left out of the video. I think this project has a lot of potential, but to function as a true fire-and-forget low-cost local recycling system, there need to be clear answers to these two points - they are the Hard Problems of this problem domain. There are undoubtedly many possible ways to address those issues, but there needs to be _some_ kind of solution for them that still fits within the "local, easy, and low-cost" bracket, and right now it just isn't clear that there is.

@manutechlab 4 күн бұрын

Thank you for your thoughts on that and I have to agree with you on most of it. This video had to be limited to 3 minutes and I did not go into these topics. It is not open source yet. Most of my projects related to this machine and the former deisgns are. If you want to have a look at them. I shredded the plastic I collected from friends and family at my university. They had a big shredder there that did a fast job. So the raw material price for me was low and the products created from the machine can be sold at higher prices than granules and be soled to an end consumer. That makes it much faster to reach break-even with this machine while their is not much man labor needed. I wrote about this in my application for the James Dyson Award, if you want to have a look into it. It was just hard to fit all of that in this video. I love the fact you took so much time and thought in this comment, it helps me a lot to find out what is still missing in the project explanation and helps me make a better job:)

I think the title is a little bit missleading in itself. It is a great looking machine but the core problem is the shredding of plastic, this plastic needs to be sorted out into the different types of plastics. Need to make sure the thermosets are not mixed with the thermoplastics. If the shredder was sorted out to do all the sorting this would be a 1 of machine, but I have doubts about that ever being feasible in this formfactor. What sort of lockingpower does the IM have? And can it keep afterpressure in the cavity itself after filling it up?
