Abstract
A debinder provides for debinding printed green parts in an additive manufacturing system. The debinder can include a storage chamber, a process chamber, a distill chamber, a waste chamber, and a condenser. The storage chamber stores a liquid solvent for debinding the green part. The process chamber debinds the green part using a volume of the liquid solvent transferred from the storage chamber. The distill chamber collects a solution drained from the process chamber and produces a solvent vapor from the solution. The condenser condenses the solvent vapor to the liquid solvent and transfer the liquid solvent to the storage chamber. The waste chamber collects a waste component of the solution.
Claims20
A debinder system to debind a printed part, comprising:
- a storage chamber configured to store a liquid solvent for debinding the printed part;
- a process chamber configured to debind the printed part using a volume of the liquid solvent transferred from the storage chamber and to dry the printed part;
- a distill chamber configured to collect a solution drained from the process chamber and to produce a solvent vapor from the solution;
- a condenser configured to condense the solvent vapor to the liquid solvent and to transfer the liquid solvent to the storage chamber;
- and
- a controller configured to determine one or more parameters of the debinding based on one or more properties of the printed part,
- wherein the controller is further configured to instruct a user, via a user interface, to position the printed part in one or more locations within the process chamber.
A debinder system to debind a printed part, comprising:
- a storage chamber configured to store a liquid solvent for debinding the printed part;
- a process chamber configured to debind the printed part using a volume of the liquid solvent transferred from the storage chamber, wherein the process chamber is also configured to heat and to dry the printed part;
- a distill chamber configured to 1) collect a solution drained from the process chamber, 2) produce a solvent vapor from the solution, and 3) collect a waste component of the solution;
- a condenser configured to condense the solvent vapor to the liquid solvent and to transfer the liquid solvent to the storage chamber;
- and
- a controller configured to determine one or more parameters of the debinding based on one or more properties of the printed part, and wherein the controller is further configured to instruct a user, via a user interface, to position the printed part in one or more locations within the process chamber.
A debinder system to debind one or more printed parts, comprising:
- a process chamber configured to debind the one or more printed parts using a volume of a liquid solvent and to dry the one or more printed parts;
- a distill chamber configured to collect a solution drained from the process chamber and to produce a solvent vapor from the solution;
- a condenser configured to condense the solvent vapor to the liquid solvent and to transfer the liquid solvent to the process chamber;
- a purging device configured to remove at least a portion of the solvent vapor from the process chamber,
- a controller configured to determine one or more parameters of the debinding based on one or more properties of the one or more printed parts;
- and
- a user interface,
- wherein the process chamber, the distill chamber, the condenser, and the purging device form a closed system and are contained within a fluid-tight unit, and
- wherein the controller is further configured to instruct a user, via the user interface, to position the one or more printed parts in one or more locations within the process chamber.
