Desktop injection, desktop SLS, (more accessible than before) FDM printing with pellet extruders, etc... So many new things coming out lately, makes me want to set up a garage factory
Desktop RIM sounds awesome, and I feel like you might be missing out on quite a few customers by only focusing the demos on printed molds. It would be great to see examples from metal or silicon molds to eliminate all bottlenecks to see how one could scale up production after first working with printed molds. Also would be great to get these units into the hands of youtubers/makers to see what they can come up with ! There are a few on here that focus on desktop injection molding etc that would be great candidates😊
We will have silicone and metal molds in the future videos. Thank you for the good wishes.
This is incredibily! I need this in Brasil right now!
I would love to test one of these machines, wish I had the following for that. If i can save the money up I will purchase just because i have small part that would be best molded like this. Great work keep up doing innovative things.
Awesome!
For doing really small things like custom lego, would the tolerances for connections, pin holes and axle holes be dependent on your 3D printer?
It depends on the printed part tolerances.
Very interesting. Where do you source your isocyanate and polyols?
For USA and Europe we have different suppliers.
I get it, kind of. You don't get to say "this only took 10 minutes" when you have 24 hours of printing and 2 hours of sanding into making a mold for a single part. But for making hundreds of parts, a machine like this would make a difference. I've done enough work with resin to understand why you might want a system that can automate the measuring, mixing, and injection of the resin.
You think of this from a home user perspective. This is build for scalability. If you have to design a part yes it takes 24h to print and 2 to sand till you have the exact model but once you do that you can reuse that mold till it fails. Again this is not necessary aimed at 1 time use molds it's more towards print farms and fast turnaround for making the same part after you print the mold
@@lauretiu Thats my point. No one cares if casting "only took 10 minutes" unless you are the little guy. At the scale where this is practical you choose this because its cheaper startup costs, not because of cycle time. So saying "only 10 minutes" is just silly.
Cool tech. That part wouldn't take 24 hours to print on a modern FDM printer but this is certainly way faster. I'd like to see strength tests of the resin since all resins tend to be weaker than traditional materials. Considering how fast it cured I would guess it's quite brittle? Typically a part like that might be injection molded with ABS, Nylon, or PP. Can the resin compete?
Without fiber reinforcement at the same thickness it can come close but not compete. With fiber reinforcement it exceeds.(its the same with injection molding but harder to achieve composite parts on injection molding) The point of reaction injection molding is upfront costs are really low with most of the benefits of injection molding.
Hmm. Design part , design reverse mold of part, fdm print mold, fill and sand mold, inject resin into mold, remove mold(does not pop out like the big dogs), resurface molded part as needed, paint as needed. It's alot more work than just plain fdm. And alot more limited in the geometries you can have though maybe not as bad as large scale molding. Still alot of work for one-off parts. If you are repeating the same part over and over it starts to get faster at production than fdm possibly.
Is it possible to switch between different resins in the system, and how much cleaning is needed to do so?
Yes it's possible but changes from resin to resin. Going from flex to rigid requires full tank flush and cleaning while rigid to flex or foam is pretty easy. We will be selling the tanks on our website too they will be $30. Removal of the tanks is 5 minute job.(6 screws and tank connection)
I mean it's cool but the injection part which is the only new aspect is just a resin dispenser?
I am whelmed.
Would it be possible to add aluminium powder into the resin mixture for cold casting ?
It would work, but it does change the viscosity. Pumps are designed to work with that. As requested, we are currently integrating pump offset values to our gui. You will need to calibrate it before the injection though.
To you sell the resin in europe directly? how much will it cost in the EU?
Yes we ship it from Europe warehouse. 1 gallon kit is $60 for Rigid resin
What makes the degassing step unnecessary?
Degassing is necessary because mixing resin by hand introduces air into it. However, when resin is mixed using passive mixers, no air is incorporated into the mixed resin.
Pressure pots are used to minimize bubbles in the resin, with humidity being the primary cause of bubble formation. After pouring the resin into the machine's tanks, the tanks are activated only during injection. When the device is not in use, the material remains inside a controlled environment, maintaining optimal conditions to prevent bubble formation.
Passive mixers also enable you to pour very slowly, extending the working time. When injecting, if air is trapped inside the resin due to the pouring process, passive mixers provide more time for the air to rise to the surface.
Is the output of the injection manual or can you give the machine the model and it will automatically detect the required amount of medium to inject?
It has two modes: manual and automatic, selectable from the screen. In automatic injection mode, you need to input the desired injection value. (this was one of the comments from our customers so we added it.)
You can take the necessary value from fusion 360, solidworks or whichever design tool you use.
@@NeckogIndustries Thank you for the swift response.
How likely are you to hit the November shipping? And is that you shipping out, or product landing in Europe?
Quite excited about an actual US manufactured tool and not another Chinese one.
November is our target shipping from US. Thank you
You haven't answered my question for the last three videos. What is the size limitation of the injection molding?
Is it possible to put together larger molds and still inject?
Thanks
Your question was answered the day you asked. You can check from other videos too.
Here it is: There is no size limitation limit is 2 gallons; as long as you fill the system you are able to use continuously.
Entire rear spoiler would be too heavy unless you have a inner core placed before(Like a closed cell foam or a inflatable inner core). Bumper and front spoiler would be ok.
Just needs 4d cnc to be affordable.
Hi. How strong is the resin part compare to 3d printed part from pla or abs?
In every axis it's better than PLA or ABS printed parts. On Z axis there is no issues due to chemical reaction of injection. Parts are isotropic meaning the durability is uniform on every axis.
@@NeckogIndustries thank you for answer. I do understand that such part is isotropic. I just thought that resin on its own is too brittle without reinforsment with some material (like fiber glass, carbon etc).
You can check our other video on durability. Polyurethanes are a bit different than epoxy resins.(epoxy is more brittle). We will do a video on polyurethane composites with glass fiber cloth.
@@NeckogIndustriesbetter how?
@@NeckogIndustries lemme introduce you to PCTG
how much is the PU per gallon?
It's $60 for Rigid Polyurethane
how reusable are the printed molds
We did test it around 30-35 cycles no problems. If longer cycles are needed we advise to print the mold as shell then inject with polyurethane as infill. This way there is no issues due to 3d print parts being too weak.
Your machine sounds very similar to me after too many taco bell burritos.
Seemed like e a cool idea given that mixing and cleaning resin can be a pain, but an additional $3000 for the printer is a bit over excessive. Also, at $1000 base price, I'd expect it to support all resins, not just resins that are tailored for the machine. Finally, you can clearly see bubbles throughout the pouring. I feel that if you used a clear resin , it would not be as bubble free as claimed. Also, what happens if someone forgets to clean it within the set time? Is the entire machine dead? Are we going to be charged hundreds for a hose and nozzle replacement? Your videos show a lot of cut edits and almost nothing up close and en detail when it comes to final products.
It supports 3rd party resins. We will be adding resin calibration files as requested. If you forget to do cleaning you just change the nozzle. You don't need any tools. You can buy it through our website or 3rd party sources. They are industry standard and costs around $2. These systems do the mixing with a mixer nozzle as long as you don't inject from a very high point and introduce air to the mixture. You won't have bubble issues. We will have more videos on the channel about different parts.
I can't get the benefits of this set🙈 why one can't just have a vacuum pump with a vacuum chamber, 2 component resin and regular syringe for the same goal?
I think that's exactly the same. Ppl just doesnt know whot resin cast can do....
I don't get it. Is all of this just to be able to reuse the mixing nozzle? Mixing nozzles for urethane is dirt cheap any way, why buy this expensive machine just to make the nozzles multiuse items in stead of single use?
How is this any different from pouring resin into a mold ..? Lmao
Plus I bet there was air bubble galore in that part
You would have to mix the resin, as he explained. To get PU to flow everywhere in a mold like that would be a total PITA by just pouring so you would have to put it in a big syringe and inject, like he did here. Then clean it all up. You're right had he just poured it after mixing it by hand there would like be a bunch of bubbles but he didn't do that. Look up RIM like he mentioned in the video. I'm not in the market for this but $500 is pretty damn cheap for a system like this and the only company i've seen making this stuff at this scale.
@@carmelol8574 $500? I see 700 as early bird and it shows regular price is 1k. Is just a pump which I assume will clog at some point. There is no way it can clean 100% PU from system after mixing.
So it might be ok for big projects, everything beyond 600-800ml of PU as you can use even syringe for that.
Also is heavy on bubbles, they don't use clear resin for that reason.
But 3d printer for 3k is just mental 😂 you can buy 6 bambu lab printers for that price and print those parts in just an hour.
Still interesting concept.
Wait...how did you fill the resin? You skipped that. You have to show the entire process otherwise I believe it's not easy, perhaps it's very messy or impossible. It didn't take 10 minutes. You printed the molded parts after then sanded then assembled then mold release then filled the resin tank and perhaps cleaning fluid, then injected then cleaned up. You're not honest by not showing and counting the real time.
For one part, yes. However the point is you can do small production runs with one cast. So it depends how many you do, as to how you divide the time up. End part is 10min per part. Mold is probably 3x 3d printing the part, as you need to make both halves of the mold then glue it all together.
But it has other benefits. You can do arbitrarily large parts without joins (as long as the volume doesn't exceed the tanks) . And the parts are stronger.
So it's complimentary to 3d printing, indeed depends on it.
@benp7328 looks like it could be useful for sure, thats not in question. However you should show the entire process and thought process. Start with the part you want to make and go from there. Perhaps an influencer would show the process without skipping so many steps. I would be interested to make a 60 shore A TPR shoe sole and a flexible foamed TPU insole.
Guys honestly the video quality is really bad… the audio still sucks and it is really difficult to watch it this way, it also make your company seem way less serious to be honest. Please get some reasonable video gear and plan it a bit better, the injection fail in the last video and the poor storytelling is somewhat more bad pr than useful in my opinion
Personally, to me it makes it feel more like a real product. I'm tired of awesome videos selling smoke.
