The HTPLA Bronze is composed of a polymer (PLA) and bronze powder, compatible with any desktop 3D printer FDM/FFF.
The bronce powder on one side offers more resistance to the filament than the standard PLA and on the other it gives a similar appearance and density to the bronze metal.
The amount of bronze contained in this material is sufficient for transmission and heat dissipation applications, resistant parts or parts with a finish that need to simulate bronze in any of its states (bright, rusty, old ...). But this percentage of bronze isn't enough to be a conductor of electricity. In the case of searching for a conductive filament of electricity, the Conductive PLA filament or the Graphene filament should be chosen.
Once the piece is printed, you can choose an infinite number of different finishes. Here are some of the Post-Processing techniques for this material:
The thermal treatment reinforces the structure of the Bronze HTPLA, giving it greater resistance to deformation at high temperatures, maintaining its shape up to 170ºC. The tempering process is very simple, you simply need a domestic oven at a temperature of 110ºC and introduce the piece about 10 minutes, having to adapt the time depending on the size of the piece, the larger, the longer the tempering must be.
The Bronze HTPLA filament has an infinity of applications, among which are:
This material has been optimized to have a lower moisture absorption than conventional PLA and get a better flow to avoid clogging, something to which some Special PLA containing fibers or metal powders are prone.
The filaments with metallic particles of Proto-Pasta; once printed and post-processed, offer a finish with an appearance and density similar to the metal used. However, in no case they will have the properties of that metal.
If metal finishes and parts containing the properties of the metal in question are desired, filaments from The Virtual Foundry Filamet range should be used. Parts printed in 3D with these materials become completely metallic through a sintering process.
It should be noted that Filamet filaments require more knowledge due to their complexity both in the printing process and in the subsequent sintering which, in many cases, is of an experimental nature.

The print is recommended to clean the nozzle by passing through it PLA or Smart Clean to avoid leaving traces of carbon fiber in it. Carbon Fiber PLA in filament state is more fragile than the standard PLA so must be handled carefully to avoid breakage. Optimum printing temperature can range between 185ºC and 215ºC according to each 3D printer. It's recommended to use hardened steel nozzles or the powerful Nozzle Olsson Ruby with a diameter equal to or greater than 0.5mm.
Printing of this filament is just as easy to standard PLA. Although it is not necessary to have a warm bed to print this filament, if she have put it at 30-60 ° C it is recommended. The adhesion of the first layer is key and probably the most important factors for good impressions. so you can use Magigoo, DimaFix, PrintaFix or BuildTak.
