Hi Folks, I have been sitting on this content for a couple years and figured I would tell you about the Gametammer tray mold that we made. I may be incorporating this tray into a new Dragonfly Eng product too. Enjoy!

It always amazes me how a brick of metal transforms to make something, that could ten,churn out thousands of something else, with very little effort. On another note, 3D Benchies are supposed to be the determining factor of the max speed of a 3d printer(still a longway off from industrial IM, apart from extreme wear on tooling?). It will be a fun project, if you could create a 3DBenchy mold(may be a buch of them in a family mold?), that blows the current world speed record(one benchy in 2+ mins.). It would be a fun project, will definitely help with viewership numbers. While searching on thing*verse, search for original 3D Benchy. It is nothing but a small boat(has some enclosed area though,may need inserts, or something more creative?). Just some 💭❤️👍

The fastest machines I've personally seen are the Husky ones that produce preforms for PET blow-molded bottles. The preforms look like test tubes but with a molded thread. Something like 48 hot-runner cavities (so no sprue to remove) with a (don't quote me on this) something like a 10s cycle so around 5 parts per second if memory serves. All hardened steel with TiN coating for mold life in the millions of shots x 48 per shot.

Thanks for the tip! I will look into 3D Benchy

@@DragonflyEngineeringlook up the speed boat challenge. It’s amazing how fast people are printing these now. I too would be curious to compare an injection molded version - I bet you could sell them as reference models for 3d printing geeks

Nice video on machining a plastics mold. We make our molds out of steel. Do you run these parts on a Hurco vm10i? If so how do you think it would handle machining steel and 3d work like you were doing?

Thanks for watching. Yes, I used a Hurco VM10i for these molds. I think the VM10i should be able to handle steel pretty well. I have run P20 mold steel on it before. Most of the work is just switching to a steel milling mindset vs aluminum. ie I pre drill most endmill Z axis lead ins, and run the RPM and feed slower, use low helix 4-5 flute mills etc. How do you like your VM10i? I have 2 and both of them give me computer / sofware problems

I currently don’t own a Hurco vm10i. I have been watching your videos and noticed the Hurco. That’s no good about your issues with them. I am looking to buy a small VMC and have priced Haas, Doosan and am now looking at Hurco. Does the Hurco creep as it heats up and give you miss alignment on your 3d work or does it have compensate. Thanks for your reply.

@@hawkprecision7878 Yes, all the vertical mills that I have used do thermal drift, even with a spindle chiller ( chillers make it much less) If I need to hold microns then I let the spindle run at cut spped for ~1 hour, then i reset the tool with a loop, then start the program. this is for small tools running 10,000 RPM. The heat is exponential to the RPM. I also spray coolant on the expossed spindle to help. The hurco has a good spindle, I had problems with Haasspindles ~5-10 years ago, randomly overheating in a cut from bearing chatter, but maybe theyfixed their spindle problems. These factors i am describing are 1-1.5 thou range of error BTW Haas Super minimill is really good

Thanks for the explanation. I also looked at a Mazak Primos 400 that runs a gantry style. Seems a good idea.
