Simply astounding! The progress in technology, materials, and the innovative mindset behind them is truly remarkable. Thinking outside the box and leveraging tools and expertise to solve problems quickly is a game-changer compared to traditional methods. Beyond the incredible engineering feats, these advancements are making a real difference in saving and improving lives. I'm immensely proud of all the participants, but I want to give a special shoutout to my friend and colleague Andrew Allshorn from 3D Squared. He's a true trailblazer in additive manufacturing, and I couldn't be prouder of his achievements. From generously donating equipment to schools to lending a hand to animals in need, Andrew's big heart shines through in everything he does. And to top it all off, his recent act of saving Freda the Shire Horse's life is nothing short of inspiring. What a proud moment for everyone in the industry!

Fabulous.... excellent experience watching this. Congratulations

I like the progress of print-produced parts. Print-production is the future.

3D printing for production is a real thing. We see this in so many of the stories we cover. A few examples with real companies - VulcanForms' model for large-scale production: www.additivemanufacturing.media/articles/vulcanforms-is-forging-a-new-model-for-large-scale-production-(and-its-more-than-3d-printing) Fortify's 3D printed RF devices: www.additivemanufacturing.media/articles/better-more-compact-radio-frequency-devices-through-3d-printing Arch Additive's medical implants from EBM: www.additivemanufacturing.media/articles/production-am-demands-process-and-procedures-more-machines-will-come-later

Nearly all of these parts are mindblowing jumps in progress for different fields, but i was very curious about the hydraulic manifold - with the large upfront cost of 3d printing and the need to have pressure sealing threads either driving up the needed precision or making it so you have to tap them later anyway, why wasnt this part just 4 axis CNC'd? Is there some internal geometry which cant be machined but increases performance?

Here's a very thorough response from Corey Dickman of Penn State: Very good question and I wish more people would ask these tough questions about whether certain applications are a good fit for AM! I agree that, in some cases, hydraulic manifolds are not good candidates for AM since they can easily be manufactured via CNC with straight / intersecting drill-ways and from solid billets. In this case, the legacy design has complicated passages with multiple direction changes and close clearances resulting in difficult to procure spares. With AM, we were able to curve these passages to alleviate routing issues, eliminate multiple drill paths and reduce pressure drop. Also, yes precision interfaces and threads do require subtractive machining on most metal AM parts due to surface roughness lack of positional control over large distances (>.005 in / in). Fortunately, interfaces are easy to machine due to their location external to the part, and with near-net shapes, can be quicker and easier to machine than solid material (especially when considering difficult to machine materials). Another challenge for AM, is that designs necessitate the removal of all non-essential material due to distortion caused by the accumulation of residual stresses in thick walls. In this AM design, variable thickness TPMS structure was used as a self-supporting filler to provide structural supports while breaking up thick walls. Most importantly, and to borrow terminology from Chelsea Cummings and Tim Simpson of the Barnes Group, this is what I consider a “pathfinder part”. Critical safety parts such as this, allow organizations to “blaze a trail through the forest” in order to mature their manufacturing competency by developing their process specifications and educating designers in the art of the possible.

nice ones. I like the ones of space propulsion. When we can see 3D print + CNC for smoth surface inside? Any company invented it?

This is a common practice, you usually CNC 3D printed parts only where you need, for example strict tollerences or face-to-face junctions.
