Stronger 3D Prints by injecting Filament into the Infill

Video Description

Visit PCBWay, the sponsor of this video: https://www.pcbway.com/ [AD] This video explores an interesting idea to make 3D prints stronger by injecting molten filament into the infill. Inspired by AIM3D’s patented Voxelfill, I experiment with different techniques—from purging into negative volumes to automatically filling infill using custom G-code. I test the impact on strength and stiffness, share my findings, and show you how to try it yourself. This technique can be applied on any 3d printer, like Prusa MK4, Prusa CORE One, Prusa XL, Creality or Bambulab machines. 🔗 Useful Links Test Files on Printables: https://www.printables.com/@JanTec Airbrush nozzle: https://s.click.aliexpress.com/e/_oDBRvco (aff) Z-Pinning Paper: https://www.sciencedirect.com/science/article/abs/pii/S2214860418310492 AIM3D Patent: https://worldwide.espacenet.com/patent/search/family/080933472/publication/EP4100235B1?q=pn%3DEP4100235B1 3D Printer Recommendation: https://www.prusa3d.com/product/original-prusa-xl-semi-assembled-single-toolhead-3d-printer/#a_aid=jantec (aff) 💚 Support Me AliExpress Affiliate: https://s.click.aliexpress.com/e/_oFiqj47 (aff) Amazon (recommended products): https://amzn.to/4b5coqD Prusa Affiliate: https://www.prusa3d.com/#a_aid=jantec (aff) Use the code "@JanTec" and get up to 200 Prusameters with the purchase of your first Prusa 3D printer! 3DJake Affiliate: https://tidd.ly/4481AFX (aff) Nobufil Affiliate: https://www.nobufil.com/?ref=JanTec (aff) Get 15% off at Nobufil with the code "JANTEC"! 📄 Sources CNC Kitchen's video about 12 3D Printing Innovations at FORMNEXT 2024: https://youtu.be/GocP5EajSRM?si=dHGGl1-VJTy7YX51 Z-Pinning Paper: https://www.sciencedirect.com/science/article/abs/pii/S2214860418310492 👐 Follow me on my other social media channels to never miss any updates: X (Twitter): https://x.com/jan_tec Printables: https://www.printables.com/@JanTec LinkedIn: https://www.linkedin.com/in/wegenerj/ 📚 Chapters 00:00 Intro 02:03 Key Concept 03:29 1.
