Copper3D is a Chilean company born by the union of engineers, physiotherapists and doctors to solve the skin problems suffered by patients using prostheses. More than 40% of amputees and also many other patients who use prostheses, suffer some dermal disorder due to the high bacterial load that these medical products present in contact with the skin, which lead to dermatitis, folliculitis, fungal infections and more. This problem is due to the fact that the materials used in medical devices are difficult to keep clean and sterilized. To cover this cadence, Copper3D has developed a new polymer for 3D printing with an additive containing copper nanoparticles, highly effective to eliminate fungi, viruses and bacteria, but safe for humans at the correct concentrations. PLACTIVE applications

PLACTIVE AN is a new nanocomposite consisting of high quality PLA and a copper nanoparticle additive (1-2%) with the advanced properties shown below:

The antibacterial action manages to eliminate 99.9% of fungi, viruses and a wide range of microorganisms.
Excellent results have been achieved in prostheses for amputees, medical applications where elimination of bacteria is essential, such as postoperative prostheses, surgical equipment and other applications. It has the certifications ISO 10993-5: 2009 (no cytotoxic potential), ISO 10993-10: 2010 (no skin irritation, no intracutaneous reactivity) and ISO 10993-12: 2012 (biological evaluation of medical devices).
This material maintains the mechanical properties of the del PLA.
Presents characteristics of thermoforming that facilitate the post-processing of the pieces made.
This filament is respectful with the environment and does not produce toxic waste.
PLACTIVE could be sterilized with UCV, ozone, Ethox or bleach; but not with dry or humid heat (autoclave) due to softening of the PLA at 55 ºC (not the additive, which remains stable until 990 ºC).

To show the world the power of PLACTIVE AN¹, Copper3D has sent samples of its product to two microbiology laboratories. Both institutions confirm that the Colony Formation Units (CFU) of Staphylococcus aureus MRSA and Escherichiacoli DH5 α, drop drastically during the first 6 hours of exposure to the PLACTIVE (> 95%), also eliminating bacterial strains up to 98% in the 8 first hours and 99.99% after 24 hours. The antibacterial power of PLACTIVE AN¹ is clearly shown in the following graph.

The advanced antibacterial properties of PLACTIVE AN¹is ideal for the entire medical ecosystem: patients, hospitals, doctors, universities; and easy to print for all types of users of a 3D FDM printer. As an example of a sanitary application, the manufacturer Copper3D has published the design of a mask for 3D FDM printing.

PLACTIVE maintains its antibacterial properties with any 3D FDM printer, regardless of the material in which the nozzle is manufactured.

3D printing with PLA is simpler and easier than with ABS. It is not necessary that the printer dock is hot, but if possible it is recommended that the base is at about 40-50 °C, to prevent any small sign of "warping" appears. The extruder temperature must be between 190 and 220 °C depending on the color and the 3D printer used. In our blog article 3D printing is explained about the main concerns of 3D printing PLA and ABS.

If your printer has a fan nozzle it is recommended that you activate it for best results. If you need to print very thin and tall pieces, you will see that the PLA plastic doesn´t give you enough time to harden each layer, so that the piece will be as if it had melted. To solve this problem we give a very simple advice, it prints at the same time at least two pieces, and place them separate at the base. Thus while the extruder is moved from one piece to another, the plastic has time to harden each layer in achieving a better result.
The adhesion of the first layer is key and probably the most important factors for good impressions. so you can use Blue Tape, BuildTak, Magigoo or 3DLac.

It is also advisable to set the "raft", which is to create a first thick layer, such as media, who will not suffer that contraction and on which to print the piece. The disadvantage of using the "raft" is that this first layer will have a less smooth.
It is advisable to lower the density of "infill" parameter for the part to store less heat. As for the "brim" (the membrane that is created around the piece) parameter is recommended to set it to never greater thicknesses of 5mm to help the first layer will not peel.

As for the interior temperature where printed it is recommended to be controlled and no drafts.
