A conductive nanocomposite which contains a mixed polymer matrix which contains a rubber and a polyether, carbon nanoparticles, and transition metal nanoparticles. The conductive nanocomposite has a nonlinear relationship between resistivity and temperature characterized by an exponential increase reaching a peak resistivity followed by an exponential decrease as temperature increases. Also disclosed is a method of forming the conductive nanocomposite involving mixing the components, aging, and pressing. The conductive nanocomposite forms a component of a heater that is self-regulating as a result of the nonlinear relationship between resistivity and temperature of the conductive nanocomposite. The nanocomposite also forms a component of a thermistor.

A method of printing a three dimensional article (201) can include forming a bottom layer of the three dimensional article (201) by spraying a dry build material powder (210) onto a build platform (230) while heating the dry build material powder (210). The dry build material powder (210) can include metal or ceramic particles mixed with a polymeric binder having a softening point temperature. The dry build material powder (210) can be heated to a temperature above the softening point temperature such that the dry build material powder (210) adheres to the build platform (230). Subsequent layers can be formed by spraying dry build material powder (210) onto a lower layer while heating the dry build material powder (210) such that the dry build material powder (210) adheres to the lower layer.

A conveyor module, small fragments of which are detectable by X-ray and/or magnetic sensors, is formed from a compounded mixture of a polyketone resin, a ferrous metal powder, and, optionally, a barium sulfate powder. The ferrous metal powder is preferably 400 series stainless steel powder, or alternatively, a 300 series stainless steel powder, iron powder, or other iron alloy powder.

This invention provides parasitic millirobots that can effectively adapt to an unstructured environment and coherently interact with diverse objects in order to fulfil various application needs. Particularly, a minimalist millirobot construction strategy by splashing composited agglutinate magnetic spray (M-spray) is adopted, which is capable of self-turning multifarious milli-/centi-objects into parasitic millirobots on-demand. Through taking full advantage of the objects' inherent structure and a covered thin drivable film, the M-spray demonstrates superior handling (from 1-D to 3-D structures) and loading capabilities (up to thousand-fold and hundred-fold of its volume and weight, respectively) while with neglectable size increment (as low as 1%) to target. Moreover, benefitting from peculiarities of online reprogramming and controllable disintegration, the parasitic millirobots can rewrite its locomotion mode according to the task and disintegrate themselves after mission accomplished, offering high adaptivity and compatibility for in vivo biomedical applications. Methods for conversion and fabrication thereof are also provided.

According to some aspects, techniques are described for fabricating sinterable metallic parts using a binder formulation that comprises a water-soluble polyamide, such as nylon. A binder comprising a water-soluble polyamide may allow a binder jetting process to produce high strength brown parts due to the toughness of such binders as compared to other water soluble binders such as polyacrylic acid or polyvinyl alcohol. Water soluble polyamides may simultaneously provide higher printhead reliability due to their water retaining characteristics and avoid the use of more expensive, toxic and often flammable solvents. Additionally, polyamide binders may react at a curing temperature with the properly selected humectants such as ethylene urea or hydantoin to create a part that is insensitive to strength loss due to moisture in the cured state.
