摘要： A multi-material printer can include a housing that is configured to be handheld. The housing can be configured to receive first and second printable materials from respective first and second containers. A nozzle can define an outlet of the multi-material printer. At least one actuator can be configured to cause first and second printable materials from the first and second containers to flow at a respective constant rate. The multi-material printer can be configured to simultaneously extrude the first and second printable materials from the outlet. The multi-material printer can be used for fabricating a scaffold from filaments comprising the first and second materials directly within the body of a human or animal.

摘要： A device and method for generating in-situ microneedles in a subject. The device includes a body, a microneedle coupled to the body, a reservoir coupled to the body, a first motor. The microneedle is positioned within a chamber at a distal end of the body. The reservoir includes a biomaterial fluid and is in fluid communication with the microneedle. The first motor is configured to activate the reservoir to expel the biomaterial fluid to the microneedle. The device also includes a temperature control assembly coupled to the reservoir and configured to set and maintain a temperature of the reservoir, a second motor coupled to the body and the microneedle, a microneedle size device coupled to the microneedle and configured to set a length of the microneedle extending from the chamber. Lastly, the device includes a user interface configured to receive input from a user to control the microneedle to penetrate the tissue to inject the biomaterial fluid into the tissue to generate an in-situ microneedle in the tissue.

摘要： A system for printing biomaterials can include a mixer having a longitudinal axis. The mixer can define a flow channel that extends along the longitudinal axis. The mixer can have at least one inlet configured to receive a first printable biomaterial and a second printable biomaterial and an outlet spaced from the inlet along the longitudinal axis. One or more mixing elements positioned within the flow channel between the inlet(s) and the outlet of the mixer. The mixing element(s) can be configured to control a spatial distribution of the first and second printable biomaterials across and along the longitudinal axis.
