I test beginner-friendly methods like 0% infill + sand/metal fill for cheap weight, and PU foam filling to turn a thin shell into a rigid, lightweight (even near-watertight) part. Then we step it up with real reinforcement: screws/rods, washers, metal grids, and carbon fiber rods to eliminate common weak points from poor layer adhesion and thin cross-sections. You’ll see clear before/after break tests, plus slicer tips like height range modifiers to strengthen only the zones that matter. This technique can be applied on any 3d printer, like Prusa MK4, Prusa Core ONE, Prusa MINI, Elegoo, Creality or Bambulab machines. 🧬 Get Carbon Rods on Amazon: https://amzn.to/45h99LZ (aff) 💚 Support Me AliExpress Affiliate: https://s.click.aliexpress.com/e/_oFiqj47 (aff) Amazon Affiliate: https://amzn.to/4ahy19T (aff) 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 https://www.reddit.com/r/3Dprinting/comments/1p2yvnn/nickels_cost_1_per_gram_and_are_very_consistently/ https://hackaday.com/2025/11/29/on-the-benefits-of-filling-3d-prints-with-spray-foam/ https://shop.carbon-shop.eu/Square-Carbon-Fiber-Rod-30x100-x-1000-mm-CFRP_1 https://www.digikey.ca/en/maker/blogs/2025/embedding-objects-inside-a-3d-print 📺 Referenced Videos @half-baked-research "Should You Fill Your 3D Prints With Foam??": https://youtu.be/Pkk9Lt-j2hM?si=M6tFWxi7AKGFzSyI @christopherhelmke printed pieces separately, paused the main print, assembled it and then resumed so the printer fuses everything together: https://youtube.com/shorts/YKZoMUWuI8g?si=NIJcvVw7qLRA_Qs8 📚 Chapters 00:00 Intro 00:35 Motivation 01:52 Sand / PU-Foam 04:46 Metal Parts 07:03 Fanttik AD 08:16 Carbon Rods 10:27 CNC Parts 11:43 Summary #3dprinting #carbonfiber #prusa #Fanttik #FanttikT1Max #FanttikF2Master #FanttikE1Max ℹ️ Disclaimer FTC Disclaimer: A percentage of sales is made through Affiliate links The links marked with "(aff)" are affiliate links, which means that I receive a commission if you buy through the link - at no extra cost for you!
