MyMat: 3DP Functional Filaments
 


TIPS FOR USING MYMAT NYLON

We like 3D printing and we enjoy making things that work, like you. All of us face challenges, the difference is that not everyone knows how to fix them.  

We understand that we have to help you for your success giving you all the possible recommendations and tips that our community shares with us. This section will bring you information about the typical and most innovative data related with our products printing, provided by MyMat community and MyMat staff.

  • LAYER BY LAYER PRINTING ANGLE: A correct printing angle layer by layer improves warping and curling behavior. We made an experiment making prints of a very long part using a 45º and 135º layer by layer configuration and we obtained better results in comparison with a 90º and 0º layer by layer configuration. 
  • BAKELITE BED: One of our community partners gave us a recommendation to print nylon onto a bakelite slide. The result has been satisfactory. The adhesion between this substrate and our materials has been very good. We have to notice that the thickness of the bakelite should be strong enough to avoid any deformation of the bed... So, if you are buying one of these bakelite layers use a strong one.
  • BED TEMPERATURE: The bed temperature will affect the printing according to your printer system. We got good results printing at room temperature beds and we recommend it in some cases. The most general case is to put it at 100ºC, it will work. 
  • ADHESION SYSTEM: We use common lacker to make our tests, but we also make our best to get better adhesion systems. One of the results we got in our research is a dissolution of PVA. We made several tests using different concentrations of this plastic in the dissolution and the results are improved using a 3-5% in weight. The success we got with this were the printing of higher thickness parts. 
  • CONTROLLED ROOM TEMPERATURE: We made tests in ambients with controlled temperature and the equipments that can control the printing chamber temperature get less warping. The nylon nature generates the warping and the curling. If you are able to control the printing chamber temperature you will relax the internal tension of the polymer chains and the warping and curling will be importantly reduced. (Do not close areas with electronic devices, they could be broken because of the lack of ventilation).
  • THE FLOW OF MATERIAL: Some of the efforts made with our nylons gave us unsatisfactory results. Sometimes the part has some black areas that are composed of accumulated material. These accumulations are because of a non-correct configuration of the material: too slow, too flow or too high temperatures (or combinations). So, try to start printing at lower temperatures, print it faster and finally you can complement this configuring higher diameter filaments (from 1,75 to 1,9) and try to use the lower temperatures. Nylon is a silky material that could be accumulated in the printing nozzle while the printing is taking place. Try to avoid this contact and you will get good results. 
  • SUPPORT MATERIAL TREATMENT: We cannot print with HIPS, the results are not satisfactory. But we recommend to use PVA filaments. We know that this material is not confortable to work with once it gets humidity inside, but we assure that if you heat it in an oven during half an hour between 40-60ºC you will get a really good support material. 
  • COLOR: We are not the first one sharing this typical tip. Some customers tell us why do not sell colored nylons and we say them that is cheaper for them to do it at home with common textile application dyes. If you prepare a dissolution of a dye in water and you introduce the nylon (white or translucent one) you will get a material in your desired color in few moments. After that we recommend you to put it in an oven less than one hour before print. The appearance of nylon will be perfect! Let your mind create the next color combination: mix, print and flow.
