The present disclosure relates to thiol-acrylate photopolymerizable resin compositions. The resin compositions may be used for additive manufacturing. One embodiment of the invention includes a photopolymerizable resin for additive manufacturing, the resin comprising: an acrylate oligomer; a methacrylate monomer; and a thiol wherein the resin may be configured to react by exposure to light to form a cured material. The resin may further comprise one or more oligomeric additives. For example, polyether oligomeric additives such as polytetrahydrofuran.

Provided herein, inter alia, are solvent and resin formulations comprising reduced fire and environmental risk, methods for producing sensor device for detection of any analyte, e.g., by printing reactive chemicals and dyes onto a substrate using large scale printing machines. Also provided is a method of preparing the reduced risk formulations and sensor device, and methods of using the sensor device. Further provided is a sensor system including an ink and a solid support. The ink includes at least one reactive chemical or dye, a co-solvent, and a resin composition chosen for reduced fire and environmental impact risk. The ink is applied (e.g., printed) on a surface of the solid support. The reactive chemical or dye is configured to undergo a chemical reaction with gunshot residue (e.g., post blast residues associated with historical and modern day black powders used in bullet manufacture) that produces a presumptive colorimetric indication.
