I have been dedicated to 3D graphics and printing for 9 years, my first printer was the CR-10 first model! 300x300x400 I created upgrades such as direct drive to be able to print TPU without problems, additional air flow etc... I also owned an Ender 3 V3 - KE for a short time and an Elegoo Saturn 3 12K sold reluctantly (but to a great friend) due to a bad skin allergy to resins! Currently owner of an A1 with AMS and an A1 mini, used exclusively for TPU!
