From what I've seen, good quality metal molds can be thousands of dollars. How do you achieve quality with a 3D printed mold? Also, how do you prevent a plastic-on-plastic part from fusing or the heat of the liquid plastic degrading a plastic mold? How many times can the mold be used? Doesn't a metal mold serve a dual purpose by acting as a heat sync to quickly cool the parts, and wouldn't a plastic mold act as an insulator? Overall, it seems very cool and useful. I'm just curious why you dont see plastic molds more often!

This mold is made of UV-curable resin on an SLA printer, not FDM/FFF. Thermal constraints aren't a concern in this application as a result. You'd be correct in assuming metal molds are more efficient in terms of time from injection to ejection due to the difference in part cooling rates, but metal molds are also likely to employ coolant channels to facilitate the rapid cooling of the part for mass production. Metal molds are the status quo due to their wear resistance and production efficiency. Printed molds are only found in the hobbyist and small entrepreneurial spaces as they're cheap to produce, easily iterable, and simple. You would never see them on an industrial scale.

Why does something that melts and squirts plastic into a mould cost so much? Is there something more complex about the machine that I'm not realising?

@@joshuaisaacs8970 An industrial injection molding machine is hundreds of thousands of dollars into the millions. The mold itself is thousands up to tens of thousands or even much higher depending on the complexity of the mold. The mold is expensive because it needs to be designed by an engineer and then machined. The engineering is expensive because you have to design the mold for proper plastic flow, for the specific injection ports, flow simulation, selecting the right materials, surface finishes, etc. Machining time is also not cheap. For consumer products, injection molding is usually only economical if you’re making hundreds of thousands or millions of copies of the part where you can amortize the mold cost across all the individual parts.

​@@joshuaisaacs8970the expensive bit is the repeatability A million parts might get made and the first is within 0.05 mm of the last Similarly, 3.144 grams of plastic is used every time

I've been saving from the moment I saw the 1.0 video. My Injekto fund is almost fully financed! 2 more months! So excited.

Dont forget to Balance the Propeller.

Honestly, I don't even know what is better - this machine or two X1 Carbon printers

That spring back (that closes when clamped), was it designed, warping from injecting and heat or from printing?

How do you know how much plastic to insert?

I can't believe you are doing that in your house in an enclosed space... might want to setup some ventilation my dude

Which machine you use to prints 3d printed mold

Brutal 👀

Saving up , just boight a bboo p1s , need that injection machine lol

So the next thing for at home making will be injection molding? I could see this being applied for costumes, cosplay, and hobby parts to cut down the costs related to small runs.

Do you have to suck all the air out to ensure the plastic fills all the mold's cavity?

@ActionBOX

No, there are escape channels for the air which are too small for the plastic to flow into.

Wow 😲

can you please make a 5255 3blade prop?

Very nice! Please read up on injection molding. This mold needs better venting. There are simple principles that will make your work more professional. Venting / draft angle / injection speed / plastic temperature / runner & gating systems.

Very nice

Resin molds are relatively common for small run injection molds. You're not gonna get anywhere the number of parts out of it compared to an aluminum or, better yet, a steel mold. But it's great for doing a few tens of parts.

And why didn't you made it to produce more than one propeller at the time?

When he scraped that part out, will scratch the mold surface down and down.

Nice.

Molding

And where did the hemi come from? Mercedes Benz!

Injection molding was good enough for Grandpa and it’s good enough for me. Don’t need no highfalutin 3D printers.

4 prop version when? 👇🏻

Try make toroidal blade

Make toroidal propeller/ fan

what material did you print the mould out of?

How to pre heat the mold😢

how much is it

Lol so you made a injection molded 3d printed finish part.

It look great and sounds cool. But i'm gonna catch you on a technicality. You wouldn't "mass" produce anything like that.

Lol GW is fucked. Im gonna make whole 40k armies like this😂😂

You can use it to make them out of carbon fiber

That air need to vent ......

Very interesting but way too expensive. I have this fondness for food and drink so they must take priority.

No way bro can make pp parts 😮

You seem to have a defect, scratch, on your mold

Why not just 3D print the propeller??

@ActionBOX

Because it’s far more fragile than a propellor made of a uniform piece of plastic, plus this allows us to choose any type of polymer we want to use. It’s also much easier to make a bunch of parts much faster 😃 Hope that helps

can't you just 3d print the propeller🤔

But how did he get the first prop out

propeller? I barely even know 'er

2k 😂😂😂

I don't like that there's an imperfection in your mold en you didn't do anything about it. See those 2 sripes in the blade..

Most commercial props have some carbon fibres in the mix....

Why not just 3d print the props
