Abstract
In one example, a non-transitory processor readable medium with instructions thereon that when executed cause an additive manufacturing machine to inhibit build material in an overlying layer of build material from fusing with a first slice formed in an underlying layer of build material.
Claims15
A non-transitory processor readable medium storing instructions thereon that when executed cause an additive manufacturing machine to perform a process to manufacture an object from build material, the process including:
- forming a first layer of the build material;
- selectively dispensing a coalescing agent on the first layer in correspondence with a first slice of the object to be formed;
- selectively fusing the build material of the first layer together based on where the coalescing agent was deposited, to form the first slice;
- dispensing a coalescence modifier agent on an unfused portion of the first layer;
- forming a second layer of the build material on the first layer;
- selectively dispensing the coalescing agent on the second layer in correspondence with a second slice of the object to be formed, including on a portion of the second layer directly over the portion of the first layer that remained unfused;
- and
- selectively fusing the build material of the second layer together based on where the coalescing agent was deposited, including the build material within the portion of the second layer directly over the unfused portion of the first layer on which the coalescence modifier agent has been deposited, to form the second slice.
A method for additively manufacturing an object from build material, comprising:
- forming a first layer of the build material;
- selectively dispensing a coalescing agent on the first layer in correspondence with a first slice of the object to be formed;
- selectively fusing the build material of the first layer together based on where the coalescing agent was deposited, to form the first slice;
- dispensing a coalescence modifier agent on an unfused portion of the first layer;
- forming a second layer of the build material on the first layer;
- selectively dispensing the coalescing agent on the second layer in correspondence with a second slice of the object to be formed, including on a portion of the second layer directly over the portion of the first layer that remained unfused;
- and
- selectively fusing the build material of the second layer together based on where the coalescing agent was deposited, including the build material within the portion of the second layer directly over the unfused portion of the first layer on which the coalescence modifier agent has been deposited, to form the second slice.
A system comprising:
- a processor;
- and
- a memory storing instructions executable by the processor to cause an additive manufacturing machine to perform a process to manufacture an object from build material, the process including:
- forming a first layer of the build material;
- selectively dispensing a coalescing agent on the first layer in correspondence with a first slice of the object to be formed;
- selectively fusing the build material of the first layer together based on where the coalescing agent was deposited, to form the first slice;
- dispensing a coalescence modifier agent on an unfused portion of the first layer;
- forming a second layer of the build material on the first layer;
- selectively dispensing the coalescing agent on the second layer in correspondence with a second slice of the object to be formed, including on a portion of the second layer directly over the portion of the first layer that remained unfused;
- and
- selectively fusing the build material of the second layer together based on where the coalescing agent was deposited, including the build material within the portion of the second layer directly over the unfused portion of the first layer on which the coalescence modifier agent has been deposited, to form the second slice.
