Copper3D MD¹ Flex - 2.85 mm - 500 g - Red


MD¹ Flex is an innovative Nanocomposite developed with a high quality TPU98A and a patented, scientifically validated and highly effective Nano-Copper additive. This unique combination of technologies brings the following characteristics to our products:

Antibacterial action has been scientifically validated eliminating more than 99.99% of fungi, viruses, bacteria and a wide range of microorganisms.

Antibacterial properties confirmed by two microbiology laboratories in Chile and USA.
PLACTIVE™ is a FDA Registered Material and EU compliant (No. 10/2011, No. 1935/2004 and No. 2023/2006).
The manufacturer also has certification ISO 9001/2015 and is REACH compliant.

Clinically tested in prosthesis for amputees with excellent results. it’s also ideal for the manufacture of other medical applications where it’s dangerous to have bacterial contamination, such as postoperative prostheses, wound dressing and orthopedic insoles.

The Nano-Additive maintains all the mechanical properties of the TPU98A material like strong & flexibility, high heat resistance (138°C), 450% elongation at break and easy to print at vel. >75mm/s.

MD¹ Flex it’s also has a food contact clearance No. 1935/2004.


This graphic shows the results of 2 studies conducted by microbiology laboratories in USA and Chile1,2. Both studies confirm that the Colony Forming Units (CFU) of Staphylococcus aureus MRSA and Escherichia coli DH5α, falls abruptly during the first 6 hours of exposure to MD¹ Flex (>95%), continuing the elimination of bacterial strains until reaching >98% elimination at 8 hours and >99.99% elimination at 24 hours.

“Keep the package sealed until ready to use and promptly reseal any unused material”
MD¹ Flex does not require a heated bed to stick well though you can set it to 0-60°C for extra assurance.
MD¹ Flex works superb with a direct drive feeder, or newer types of Bowden FDM or FFF technology 3D printers.
• By changing the infill/amount of walls you can create the perception of a higher/lower shore than 98A.
• Storage: Cool and dry (15-25 ̊C) and away from UV light. This enhances the shelf life significantly.
