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. However, in no case they will have the properties of that metal. 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. 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. Game pieces or replicas of ancient figures.Jewelry like rings, pendants or bracelets.Pieces with appearance similar to brick or clay.The Bronze HTPLA filament has an infinity of applications, among which are: The tempering process is very simple, you simply need a domestic oven at a temperature of 110✬ 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 thermal treatment reinforces the structure of the Bronze HTPLA, giving it greater resistance to deformation at high temperatures, maintaining its shape up to 170✬. Image 1: Figures printed with Bronze HTPLA. Heat can be applied to make the process even faster. Patina (oxidize) naturally or in an accelerated manner with hydrogen peroxide (apple cider vinegar) and salt (50/50).Polish with sandpaper to obtain a smooth, shiny and light-colored surface finish.Polish with a rotary machine with a cotton tip and a polishing compound on the high areas to achieve a high gloss.Paint the deeper areas with a dark color to highlight the contrast of colors.Treat the surface with steel wool for a dark appearance, but at the same time smooth and shiny.With a wire brush expose the metal so that it rusts or get a glossy and satin finish.Apply a heat treatment to the piece to make it more resistant to harsher environments and more resistant to wear.Here are some of the Post-Processing techniques for this material: Once the piece is printed, you can choose an infinite number of different finishes. In the case of searching for a conductive filament of electricity, the Conductive PLAfilament or the Graphene filament should be chosen. But this percentage of bronze isn't enough to be a conductor of electricity. 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. 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 HTPLA Bronze is composed of a polymer ( PLA) and bronze powder, compatible with any desktop 3D printer FDM/FFF.
