This is super cool, and maybe I don't know your target audience, but you don't need to frame this as being strong where 3d printing is weak. A lot of 3d printing folks will point out (legitimate) critiques like (1) were those actually the same thickness? was this a fair comparison? (2) you can print in very strong materials like Polycarbonate and PEEK, as well as durable materials like TPU, can you do that in injection molding? (3) how much post processing does injection molding require compared to 3d printing? When I print the part often just comes out done! You can avoid all of these critiques if you position yourselves as *complementary* to 3D printing instead of in opposition. So for example. "Ya, 3d printing is great, but what if you need equal strength along all dimensions regardless of layer lines? Use injection molding! Use Flovv!"
Love the comment. It's a small and niche market. Even if you print with very strong materials layer adhesion will always be a problem(the parts in the video are done with the same thickness saying that it would not have mattered if 3d print part was thicker because of layer issues. It was also printed at 55C chamber temperature). We are definitely not opposing the 3D printing thats why we have our own combination of it.
I like that it sounds like an eldritch horror
Oh this will be a gamechanger
I like how the camera man was the only one smart enough to wear gloves. PPE...ahhh...my skin or eyes aren't on fire so I should be fine.
Cool product
very nice update video showing the flovv more and the injection process.
Why you will need a "beer dispenser" when you can pour directly from the bottle that resin?
You can't pour it from the bottle, it's a 2 component resin. Meaning you need to mix it to activate it. It takes time to manually mix it, then your mixing introduced air bubbles which you need to degas, then fill it into something like a syringe that can provide pressure so that you can fight the flow restriction of the mould (not every mould is flow restricted but many have to be), then fill that into a mould, it's an arduous and messy process. Due to how long the process takes, you need to work with slow resins, let's say pot life of 20 minutes, which will take about a whole day in the mould to become rigid enough to demould.
This, if you had a resin with pot life of 1 minute, it could totally use that, and the item would be sufficiently pre-cured to demould in minutes. That's a bit of a pipe dream, realistically the fastest resin you can buy is maybe 5 minute one and it takes a little while, but a whole lot less than 20 minute type, meaning you can also cycle the moulds quicker, it's maybe a one hour wait not a day long wait. The mix nozzle here doesn't introduce air into the mixture once it gets primed.
@@SianaGearz mixing syringes are existing btw
@@SergeiSugaroverdoseShuykov Maximum capacity only 50ml and that syringe costs 2€ and is STILL finicky. You might construct something nice using disposable mix nozzles, but like... there it is, these guys have solved the problem for you. And while not cheap, it's also not expensive for the amount of work it can save over the medium term - provided it's reliable, which is something they have yet to prove.
@Neckog Industries If you’re looking for Beta testers please let me know.
How is this different from mixing urethane in a vat and pouring it with a funnel? If it flows like water into an open mold, it won't gain the benefits of mold pressure.
I would be interested in reviews by the usual 3d printing nerds
Maybe it'll be handy to have 2 buttons on the nozzle.
Holding both gives you highest flow, while releasing one gives you a lower flow rate to top up & prevent spills.
Looking forward to see where this can go.
Makes sense. A proportional trigger would probably be better. We will look into that. Thank you for the input.
@@NeckogIndustries Proportional trigger might be more difficult to control reliably. It can be difficult to pay attention to the pressure besides paying attention to the mould, while using one or two fingers is easy. Worth testing one way and the other. Makes sense to also test with people who aren't very manually dextrous, less good at multitasking, and are not double action airbrush trained. And remember, the universe will always find a customer who's worse at things than you could ever imagine.
Also you know what would be good? BUTTONS. Not touchscreen. I mean touchscreen is nice if you need to switch a ton of modes or finely adjust a ton of settings, there's a threshold of complexity where that's the only way, but come on, touchscreen and droplets of resin on your gloves, no, that's a combo one doesn't wish on enemy.
Nice video, and I appreciate the transparency about the process steps and cost. The big benefit of the technology here vs plastic injection molding is the basically unlimited shot size. I'm an engineer professionally but I also design miniatures and buildings for tabletop gaming on the side. I think with the large shot size this is a feasible solution for tabletop scenery that would otherwise break the bank in 3d resin or take days to print on FDM.
Unfortunately, my hang up is the labor required to separate and clean the molds between casts. If I had a molding press with ejector pins, then we'd be golden.
We do M6 screws as ejector pins. It helps greatly with removing the part. The chess pieces we have on our website had these ejector screws on the mold. Slowly tightening them pushes the injected part-out. We will include this on the next video.
@NeckogIndustries Very clever solution. Looking forward to more videos.
So how does it work? A few peristaltic pumps for resin plus another for the purge media? I see the clear nozzle has turbulent mixers like JB weld epoxy tips, then a control board to dose it in the correct ratio? If so that's a cool implementation!
You could also consider an add on module, perhaps integrated with a slicer plugin, so when the molds are created an automatic top and bottom are generated with locating/retaining pins to hold the mold, and some kind of pressure transducer that interfaces with a thin wall section of the mold can detect when it is full, since peristaltic pumps might not be able to pick up on the resistance created by the backpressure of a filled mold. All this would look similar to a hydraulic press. It would also be relatively easy to implement a vacuum pump into the flow path to help ensure no bubbles, either direct in line or with a consumable silicone check valve that is placed in the flow path, so small batch production runs could be completed while maintaining the vacuum in the system.
Just a though though :)
We are working on a software to automate the mold manufacturing at the moment we have a service called DaaS(design as a service) just for mold making. We are not worried about bubbles due to nature of RIM systems bubbles are not an issue. We don't use peristaltic pumps flow control(too little output with less control), cleaning wouldn't be possible with peristaltic pumps. System does have a vacuum pump on it.
We will introduce automatic injection setting which will be adjusted before injection for manufacturing same parts.
@@NeckogIndustries Oh that’s awesome! You really are including a lot considering the price. Have you considered who, if any, influencers you will be sending them to? I can see some like punish props being able to really highlight this system.
Teaching Tech, Makers Muse, 3D Printing Nerd…. and AuroraTech plus a few more. Get them review models. Huge audience and all of them top notch makers. Edited to add CNC Kitchen.
I'd love to get this to make aero components for cars that I'm now making out of fiberglass which is insanely time-consuming with horrible noxious fumes.
Can this make an entire rear spoiler, bumper or front spoiler? Side skirts?
Basically what is the size limitation of this system?
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.
Its mentioned that the Flovv works with 3rd party resins, can you go into more detail on that? Does the touch screen allow you to set a mixing ratio? Does the colour pigment adding system allow you to select a percentage of the total volume/mass? Etc.
For example, one product I use is 120:100 A:B +
We calibrate the mixing ratios for each third-party resin by taking into account the viscosity changes at different temperatures. The process of adding color is manual rather than automatic, as automating it would be prohibitively expensive to maintain reliably.
Every manufacturer produces resins with different viscosity profiles that vary with temperature. Our device is calibrated specifically for each resin, although it would function reasonably well even without precise calibration.
We are cautious about adding a pump-offset feature, as it would require customers to remove the nozzle and test it multiple times. However, we are open to feedback and will consider adding this feature if there is enough demand.
The hose from the device to the tip of the nozzle is 2ft/60cm long, which is ideal for inserting the nozzle into a 3D printer or using it in a casting/injection system. We can offer a longer hose option, but this would increase the amount of scrap material. Please share your thoughts on this.
You can use our system with our resins or Smooth-On, Polytek resins. We will continue to expand our library of supported materials based on customer requests.
Thank you.
@@NeckogIndustries thanks for the reply, that's some good information.
I hear what you're saying with regards to calibration, although I guess I don't understand the material science well enough, I have used some incredibly viscous epoxies with 100:10 mixing ratios for example, as well as very 'thin' PUs with more standard 100:100 or 120:100 ratios. From your reply it seems you have calibrated and tested a selection of 3rd party resins to create the profiles? Does that mean the customer is locked in to whatever your library contains? What does that development plan look like in terms of what resins you'll support?
Apologies these are quite detailed questions, but I wouldn't want to buy a device that appears to make my small scale manufacturing efforts significantly easier, to then find out I could only use it for 50% of my products due to a specific resin not being in the system.
How difficult would it be to add a user set ratio to cater for all?
Is there an upper viscosity limit the pump can handle?
I understand the point about the pump offset / fill amount, however (ignoring temperature) the mould is always the same size per part, so after trial and error (or calculation on the flovv-e) it would be hugely beneficial to be able to set an injection amount, fill it and know that it's full, especially when using very fast cure resins.
I assumed as much on the hose front, and in most cases probably not an issue. For my use case which is slightly above hobbyist my moulds are sitting at the bottom of a pressure pot and the flovv would be on the worktop so would need double that length at least. Excess scrap is a trade off but one I'd have to take. If the hose is replaceable maybe this could be an up-sell / optional extra, but wonder how that works with your calibration going from short to long hose.
I am very encouraged by this, obviously I am looking at it for a small scale manufacturing setup rather than pure hobbyist scale, but with the ability to cast parts more easily I feel more and more hobbyists will start churning out parts and also need some of the requirements I'm proposing.
Thanks
Yes for every resin, device is calibrated to that resins profile. Our plan is to support every resin including epoxies and platinum cure silicones. We were planning to lock resin profiles. But we have gotten few requests from different countries. We will have an open source material setting library with our customers.
Small scale manufacturers is our market, so you can ask and provide input as much as you like. Adding a user set ratio is really easy also we are planning on it.
Pump can basically pump whatever fluid we put even the silicones but with changed viscosity upper and lower flow limits change.
Calculating the injection shot is already in the works. Even with the fast curing resins working time is not a problem since it comes out the nozzle mixed. It essentially delays the exothermic reaction.
We will plan a longer hose option and test it. Longer hose means a bit more positive pressure on the pump end but since we run over-powered pumps this won’t be an issue. Priming and cleaning timings will change so scrap will increase.
@@NeckogIndustries couple of follow up questions before I put my deposit down 😅
I see you have to fill up the flovv resin tanks with your parts A and B, how does one go about emptying the tanks if not all resin is used / a different resin is needed / the machine will be standing for some time?
Is there the possibility you could forgo the tanks and have hoses going direct to the containers the resin comes in (with a universal cap or similar)?
Will you have EU retailers of your cleaning fluid? Or an alternative solution available?
Thanks
You can ask as many questions as you want. No worries.
1.By removing the injection handle, you can run the fluids through the system into the containers. It's just three screws to take off.
2. You can unscrew the nozzle by hand, then empty one tank, followed by the other.
This method is only possible with the least viscous fluids, and the containers must be special. Proper mixing isn't possible at low temperatures or with flexible resins. We work with a wide output range(flow range). If we were to use containers output control would be very limited.
Yes, mold release and cleaning fluid will be available for the EU, shipped from our EU warehouse. We tried alternatives like acetone, but their cleaning performance was inadequate, and they are flammable, which is problematic.
Looks great but I am curious, why ABS and not PLA for the mold?
I dont see any functional difference and its much easier to print with PLA
For this mold, PLA can be used as well since its thin structure prevents excessive temperature rise during curing. However, for thicker parts, the heat generated during curing can deform the mold. Therefore, we recommend using ABS, and sometimes PETG, for mold-making due to their better thermal stability.
@@NeckogIndustries What about ASA?
ASA works too.
@@NeckogIndustries What about PVA? One big problem with any injection mold is the design of the part has to allow the part being released. However, if you want your part to be made by urethan due to its strenght and other material propertys - could you print the mold with PVA with geometrys normaly not possible (of course, with chanels alowing air coming out, so everything can be filled) and than afterwards simply desolve the mold to release the object?
@@oleurgast730 We should make a video on that. It would work really nicely.
would it be suitable for miniatures and tabletop themed molds ? or is it more likely for prototyp building ?
For miniatures you would need silicone molds. It's can be used for both.
What is the max volume I should be able to expect? Can I do a car hood? Fender? Center console?
With the elegoo orange storm giga unlocking large build volumes for 3d printed molds, the flovv seems like it could open a ton of doors in the automotive space.
And any chance we can see some form of external tank option if we want to go over the 2 gallon limitation?
Device has two 1 gallon tanks but as long as you fill the tanks you can continuously inject.
We are planning a automotive part with glass fiber reinforcement. With polyurethanes you can produce composite panels under 1 hour(provided you have a mold)
@@austinlambert3994 Not without serious modification. As long as you keep the filling the tanks part under 5 minutes you can technically do it without anyone helping. It's better to have someone filling the tanks though.
@@NeckogIndustries I'm very excited for that video.
what benefits are these using the injection over just pouring it in there?
Hand pouring:
Introduces air into the resin.
Reduces the work time.
Resin is stays fresh inside the system
Less material is used
Takes much less time(from priming to filling the mold less than 5 seconds)
Much less exposure to chemicals
so you have a printed part and a mold ? I dont get it
It's a desktop injection system with a purpose formulated mold release to use 3D printed molds.
When is it going to be released?
20 June Kickstarter with end of the year deliveries.
OK, we'll wait to end of year after you fulfill the Kickstarter campaign.
Anyone else get War of the Worlds vibes
Nice. Just one comment. PLEASE get rid of the looped music. It's annoying and messes with the sound of your voice. Otherwise, good luck!
Urethane is not toxic ?!?? You do not need safety equipment?
Do you know how much money I'd lose of I switched from 3D printing to injection molding?! $300 up front, cost of electricity, cost of filament, less than a day later, and I have a part I won't need to replace for years. Idk if I'll even watch the video with that intro. I've been rightfully very critical of 3D printing over the years as someone who uses it, but this just seems vindictive lol.
PU resins cost a fortune and have short shelf life.
Looks very safe for u to use. No breathing protection, no glowes, no eye protection...
And that machine spits out toxic resin and solvents... Good work, good work..
NOT!!!
Now compare a part designed for 3d printing with injection molding.
Oh wait, you can't mold actually useful shapes that better accomplish the intention of the part and molding is extremely restrictive in shapes that actually mold? Yeah that about sums it up.
Don't straw man 3d printing.
what they are doing is pretty cool. PU has extreme properties you cant get with FDM. take a step back
@@alexportiiii6414 What they are doing is misrepresenting fdm. They can have the best product on the planet and I'll call them out for a strawman. "Look I used a 3d printer wrong" only makes them look bad.
