What Print Speed Should You Use for TPU Filament?įor TPU filament, the recommended printing speed falls somewhere between 15-30mm/s to make high-quality parts. One user of NinjaTek NinjaFlex TPU filament says that a bed temperature of 230☌ has worked out great for him along with using a 40☌ bed temperature.įor reference, let’s take a look at the printing temperatures of some top-rated TPU filaments on Amazon. You can experiment with different values in this range to find out what works best for your 3D printer setup. The bed temperature for TPU is somewhere between 45-60☌. You should always use the temperature value provided by your filament manufacturer. Increasing or decreasing the temperature beyond those values can lead to certain print imperfections such as warping, stringing, and blobs. The best printing temperature that you should use for TPU usually lies between 200-230☌. What Temperature Does TPU Print At? Printing & Bed Temperature It’s actively used for making footwear, automotive parts, medical tools, sports equipment like bands, and much more. Variations in TPU involve changes in stiffness, softness, and flexibility.įilaments like ABS, PLA, or Nylon cannot fulfill the role that TPU plays in the 3D printing industry. Looking at TPU’s chemical composition, there are soft and hard segments present that lend this filament the adaptability it has. TPU is simply one of the many types of TPE that is best suited to FDM 3D printing because of its highly desirable properties. Īll flexible 3D printer filaments are derived from Thermoplastic Elastomers (TPEs). TPU is an ideal choice for parts that require flexibility, strength, and durability. It is a mixture of rubber and hard plastic that makes this material highly durable with enhanced physical properties such as impact and abrasion resistance. TPU or Thermoplastic Polyurethane is an extremely flexible 3D printer filament that’s growing in popularity. If you want, you can check out my article 30 Best 3D Prints for TPU – Flexible 3D Prints. This article is a simple yet in-depth guide on how to 3D print TPU filament just like the pros do, so stick around to see how it’s done and get your questions answered. Also, TPU easily absorbs moisture so it’s best to keep it dry in a dry box or an airtight container with a desiccant. Cooling fans are not required with TPU, and a print speed of 15-30mm/s is recommended. To 3D print TPU, you should use a printing temperature between 225-245☌ and a bed temperature between 20-60☌ for the best results. Making high-quality models with TPU, therefore, definitely takes some knowledge, which is why I’ve put together this article to show you how to get amazing TPU parts. 3D printing with a flexible material like TPU can get challenging at times since it’s generally regarded as a difficult material to print with.
