In order to obtain 100 % metallic pieces with the metallic filaments of The Virtual Foundry, it is necessary to subject the pieces to a sintering process. This process seeks to eliminate the polymer (PLA) existing in the piece and fuse the metal without losing the original shape. This process requires an oven (open or vacuum / inert), refractory powder and crucible.

The crucible is a ceramic recipient in the form of a vessel where the piece to be sintered, covered with refractory dust, is introduced. It is manufactured with a mixture of graphite, silicon carbide and clay to offer the ideal properties for sintering: good thermal conductivity, high thermal resistance (up to 1600 ºC) and good resistance to thermal shock.

This crucible is compatible with all types of ovens (gas or electric) and to perform the sintering process or melting gold, silver, bronze and other non-ferrous metals. To meet the needs of each user, the crucible is available in different sizes, which conform to the standard measurements of each type and size of oven.

Model	Dimensions (A x H x B mm)
A0	60 x 67 x 41
A0.5	70 x 80 x 40
A1	79 x 97 x 55
A2	95 x 109 x 61
A3	105 x 127 x 70
A4	114 x 141 x 76
A6	130 x 165 x 95
A8	156 x 184 x 108
A12	171 x 210 x 121

The user who wishes to obtain 100 % metallic parts after printing a piece with Filamet™, should be clear that, not only does he need a crucible according to the size of his oven, but also the pieces he wishes to sinter. If you do not have an oven with the necessary properties to sinter the printed parts with the Filamet™ and get the final properties of the material, you can contact us and we will assess its viability through our collaborators with the capacity to perform the post-processing necessary to obtain the desired final result.

For sintering in an open or vacuum / inert environment, the same steps must be followed before introducing the crucible into the oven.

Before inserting the piece into the crucible, a 1.25 cm layer of Al₂O₃ should be placed at the bottom of the crucible, then position the piece on the Al₂O₃ and in the center, without touching the walls. In the case of sintering several pieces at once, there should be a separation of 1.25 cm between them. Subsequently, the piece is covered with Al₂O₃, leaving a 1.25 cm layer on the top, beaten in a crucible so that the powder is distributed around the entire piece and crushed so that it is completely compacted.The next step would be to configure the oven with the sintering process according to the metallic filament (Filamet™) that will be used to print the piece.
