Abstract

A system for generating a user-adjustable furnace profile, comprises a user interface configured to receive one or more materials properties from a user, a processor, and a memory with computer code instructions stored thereon. The memory is operatively coupled to the processor such that, when executed by the processor, the computer code instructions cause the system to implement communicating with a furnace to ascertain one or more thermal processes associated with the furnace, identifying one or more object characteristics associated with an object to be processed by furnace, and determining a thermal processing parameter profile of at least one thermal processing parameter corresponding to each of the thermal processes, based on (i) the one or more part characteristics and (ii) the one or more materials properties, the thermal processing parameter profile characterizing a cycle of the one or more thermal processes.

First claim

What is claimed is:

1. A method of generating and employing a user-adjustable thermal processing parameter profile for a sintering furnace, comprising:
receiving, through a user interface, one or more materials properties desired in an additively manufactured part, wherein the material properties include one or more of (i) a hardness, (ii) a ductility, (iii) a microstructure, (iv) a material content, (v) a surface property, and (vi) a transverse rupture strength;
communicating with a sintering furnace to ascertain one or more thermal processes associated with the sintering furnace;
determining a thermal processing parameter profile of at least one thermal processing parameter corresponding to each of the thermal processes according to the desired material properties, the thermal processing parameter profile characterizing a cycle of the one or more thermal processes;
employing the thermal processing parameter profile to conduct the one or more thermal processes with the sintering furnace; and
processing the additively manufactured part according to the one or more thermal processes.

2. The method of claim 1 , further comprising communicating with the user through a graphical user interface, and, based on the communicating, one or both of (i) guiding the user to an outcome of a cycle of the thermal process and the materials properties of the part and (ii) directing the user to the outcome of a cycle of the thermal process and the materials properties of the part.

3. The method of claim 1 , further comprising receiving and implementing user direction regarding surface modifications to be applied to the part in conjunction with the one or more thermal processes being applied to the part.

4. The method of claim 3 , further comprising notifying the user of subsequent user direction that would conflict with the one or more thermal processes corresponding to the first user direction, and preventing the system from implementing changes associated with the subsequent user direction that would conflict with the one or more thermal processes corresponding to the first user direction.

5. The method of claim 1 , further comprising receiving user input configured to tailor the one or more process parameter profiles according to specific result requirements.

6. The method of claim 1 , wherein the at least one thermal processing parameter includes at least one of (i) temperature, (ii) furnace internal atmosphere composition, (iii) chamber pressure, (iv) gas species, (v) gas flow rate, and (vi) furnace load.
