Whenever it comes to this time of year, you get the roll ups of the past year, well of course why would this year be any different. So these are believed to be the Top 10 AM stories of 2024. https://lnkd.in/gaK-85SJ I have to say, I do really like the new 3MF file format, which offers a less data-intensive way of recording part geometry, as well as include details about the build preparation, material, process and more with approx. 1/10th of the file size. Also the adoption of Implicit Modeling?which is more of a “recipe” for the geometry, as opposed to Explicit where shapes are modeled by explicitly describing their boundaries — in other words, the vertices, edges and faces that define the surface of the shape. Geometries are typically represented either with boundary representation solid models or a triangle mesh. Plus as indicated in the list there has been a big adoption by the military sector over the past year, which I am sure is only going to grow further. And of course there have been some really cool parts produced! #aviation #research #development #innovation #technology #engineering #design #manufacturing #additivemanufacturing #3dprinting #4dprinting #rapidprototyping #advancedmanufacturing #digitalmanufacturing #smartmanufacturing

PicoGK just won an award. For almost a decade Simone and Christoph V?lcker have been scouting the world every year, for the most advanced #3Dprinted objects and related technologies to celebrate them in the 3D Pioneers Challenge, where a large jury of industry experts has the unenviable task of selecting a few winners. The quality of the entries is always amazing, this year ranging fro 3D-printed skin, to the largest-ever 3D-printed house (45m!), and anything in between. So, we are more than happy to win the award for the digital category with PicoGK, our open-source geometry kernel for #ComputationalEngineering. We believe #3dprinting is held back by a outdated and expensive conventional software. When we built the technologies last year, on which we engineer anything from 3D-printed #rocketengines to #electricmotors, we made the unconventional decision to give it away for free. We believe open access to an advanced software stack that supports design for additive manufacturing #DfAM, will help engineers all over the world to finally unlock the potential of #3DPrinters, and lift their profession to a higher level. The project that prompted the writing of PicoGK (pronounced "peacock" after the birds roaming the streets in our part of Dubai) was a highly complex one. Josefine, in cooperation with Max Horn and Timo Schr?der at the Fraunhofer IGCV wanted to build a multi-material metal aerospace part (an #Aerospike rocket engine). The object has extremely intricate geometries, cooling channels, manifolds, hundreds of coaxial swirl injector elements, all interlinked with integrated piping. No #CAD system could have hoped to handle the geometry, and no human engineer would have the patience to model it. Only a #ComputationalEngineering Model (CEM), an algorithm feeding construction logic into PicoGK, was viable. But even more challenging was the fact that we wanted to print steel and copper in one Nikon SLM Solutions printer, using the then-experimental Fraunhofer process. The intricate geometries are fused at high-resolution. Small overlaps had to be generated to avoid the lateral delamination of the two metals which have different thermal expansion coefficients. Rules had to be derived that explained why some regions printed well, why others failed. It was a trial by fire for our emerging kernel (and for everyone involved). But at the end, we had both a robust geometry kernel, and an object that is stunning to look at. If you are at the RapidTech 3D show in Erfurt you can see the Aerospike at the 3D Pioneers Challenge exhibit, as well as the Fraunhofer booth. We are happy to be taking home the recognition that comes with the award. We hope you will use PicoGK to build amazing things.

But wait, there’s more… Have you ever needed to automatically flip a pot in your production line without the use of robots or actuators? Wait no longer, the iPot-flipper 180-Z3XY is here! ?? Seriously, though, this is a common scenario in production lines where a jar is in one orientation for washing, for example, and then flipped around for filling. Yes, you could absolutely create this type of passive part rotating device tunnel in CAD, but it can be a somewhat tedious process if you do a lot of production lines. And it can be quite hard to mentally visualise how the 3D path should look if, for example, you are designing for a square or odd shaped pot. So, just to see if it was possible to automate the design of a passive part rotating device, I developed a little nTop workflow that ‘physically’ generates a 3D path of the part being rotated as it travels along the path and then uses that to create a tunnel that does the job. So import a new part, set a couple of parameters, and less than a minute later you have your passive part flipper ready to print. Here’s the process I used to create the workflow: 1.???????Import the part. 2.???????Use the ‘equidistant points on curve’ block to create 180 points along a curve (straight or curved). 3.???????Translate the physical part to each of those points and rotate each by 1 degree more than the previous one using the ‘sequence’ block to create a sequence of angles. 4.???????Boolean the sequence of rotated parts together with a generous fillet to smooth the transitions. 5.???????Shell outward by whatever thickness you want the tunnel to be, plus a clearance distance. 6.???????chop off each end to crate the part entry and exit at the ends of the tunnel and import CAD created inlet and outlet ramps if needed. 7.???????And, voila, you have your automatically generated pot-flipping tunnel. Now just re-import a new pot and you get a new tunnel. And it works like a charm! ?? #cdamlab #CAMMD #uoa #3dprinting #additivemanufacturing #dfam #productionlines The University of Auckland ASTM Additive Manufacturing Center of Excellence Wohlers Associates, Powered by ASTM International

?? Stop Relying on STL Files for Additive Manufacturing ?? If you’re still using STL files as the backbone of your additive manufacturing process, it’s time to rethink your approach. While STL files have been an industry staple for years, their limitations can compromise the quality and efficiency of your 3D prints. The Problem with STL Files 1?? Lack of Precision: STL files approximate your design using triangles, which can distort critical details, especially in complex geometries. 2?? File Size Challenges: Higher resolution means larger files, leading to slower processing times and potential system crashes. 3?? Data Loss: Unlike native CAD formats, STL files strip away important design intelligence, making modifications and validations nearly impossible. The Better Approach: Approximated Geometry By working with advanced solutions like Kubotek Kosmos 3D Framework, you can use B-rep (Boundary Representation) geometry instead of relying on STL. This method preserves the integrity of your design while offering the flexibility and accuracy needed for high-quality prints. Here’s how it works: ? Greater Precision: With B-rep geometry, you can use exact models for your project, maintaining the fidelity of curves and surfaces to ensure your print matches the original design intent. ? Optimized Workflows: Streamline the data preparation process, reducing file size and computational demands without sacrificing quality. ? Design Integrity: Keep valuable design information intact for easier modifications and seamless collaboration between design and manufacturing teams. Why This Matters for Additive Manufacturing When precision is critical—whether for aerospace, automotive, or medical devices—your geometry matters. Switching from STL files to a more advanced approach ensures better part accuracy, smoother surfaces, and fewer errors. Let’s move additive manufacturing forward by leaving outdated file formats behind. If you’re ready to elevate your workflow and deliver high-quality prints, it starts with smarter tools and better data handling. What challenges have you faced with STL files?
