There are more and more injection moulding companies that are taking the same approach to 3D printing of smaller machines with a quicker turnaround. I was just quoted 4 days ago for a project to be injection moulded and was a little surprised. The quote was 4-6 weeks for the mould to be made (quicker and more expensive if they made it state-side instead of in China) and then they say about 10,000 parts a week. I could get as little as 1 part made or hundreds of thousands, with the cost going down with more purchased at once of course. Aside from the $8k mould, it would be about $4pp if I got 100 made or $1pp if I got 10k made. They retain the mould, so when I need the next batch the turnaround is quick. I was thinking of injection moulding for the consistency of it as well as the speed to increase production versus the limited ability with 3D printing. That said, it costs me about $0.30 and 3.5 hours to print the part (1 hour on the P1P) and with my farm now over 40 printers, that is about 6 parts per printer per day (on the Enders) or 6,700 parts across them all in the 4 weeks it would take for the mould to be made. It is cheaper, the parts are already in my hands to package as we go instead of boxes worth at once, and if anything needs to be customized or changed it can be done on the fly. If I want to change the colour or add a variation (family mould with injection moulding) then there is no extra cost to do so. Both methods have their uses, but 3D printing holds up really well when it comes to mass production of certain parts.

I agree. I went down is route as well and came to the same conclusion. I wish there was a way to make injection molding like 3D printing. I would rather 3D print a mold with lots of parts and then use a smallish injection molding machine to crank out many parts quickly. The great thing with Injection molding too is you don't need supports and you could use ABS plasics without any seam lines. I looked a the Buster Beagle project but it seems really complicated for an unreliable end result.

Not really if you wanna do a more equal comparison take a desktop injection machine like Action BOX or others and all the logistics issues you were putting on injection molding are gone and the race is lost. I like the work you guys are doing pushing the limits in 3d printing farming but as 3d print lovers you are getting blind by just looking for all the niches were 3d printing is "better" yo defend your services, which is good for your business, but then you forget everything else that could actually increase production for the same service (making plastic parts on demand), and I understand, I also love 3d printing and own a farm, but as all manufacturing machines, they are tools each one with their pros, cons and their own applications. My point is: Expand your factories capabilities to more desktop/semi industrial manufacturing options, there are also other process out there like vacuum forming were companies like Mayku are doing some interesting innovations. Many Chinese plastic injection factories are now expanding to 3D printing farms with fast shipping service and low cost to compensate that gap, how are you gonna compete with that?

3D printers scale linearly in cost and production. Not to mention the adaptability and on demand capabilities. Injection molding scales a little more sharply in cost and in production capability. Both have their use case scenarios. If you had a good CNC machine, you could probably run a hybrid model with both production techniques in house.

FYI you also forgot to mention the time, cost, and design of the mold for each separate mold.

Good point. Though to be fair optimizing a design for mass production 3D Printing can also take some time to do it right.

@@slant3d agreed but cnc mold build time and mold materials are expensive and time consuming also if it is not right the initial expense and time go up dramatically.

But lets look at an example that its not you that has the farm, but lets say there is an enormou, like 1000+ machines, everything being equal, shipping and waiting and everything, printing is faster than moulding because there are no mould, ut takes a model and makes it happen immediately, no need to make a mould, let alone make a mould for every iteration of the product Not everyone lives next to you in the us, so the argument about shipping doesnt apply to someone living far from you or the injection moulding factory

You left out the part to have the mould itself made. That can take months alone before you even reach the production stage. I used to work CNC machining and plastic injection mould design in another life. Not a quick nor cheap endeavor.
