Additive manufacturing (AM) has created the possibility of replacing traditional manufacturing techniques with faster, versatile and cost-effective production options. Here, we employed AM techniques to fabricate silicon carbide (SiC) radiation detectors based on commercial 4H-SiC wafers. Platinum (Pt) nanoparticle inks were synthesized and printed onto the surface of a 4H-SiC wafer using an aerosol jet printing technique to create Schottky diodes for radiation detection. The additive printed detectors were characterized for surface morphology through a scanning electron microscope (SEM) and atomic force microscope (AFM), and electronically by current-voltage (IV), capacitance-voltage (CV) and finally by alpha spectroscopy measurements. Lastly, the printed detector achieved an energy resolution of 3.24% FWHM at 5.486 MeV, compared to 0.62% FWHM of a SiC detector fabricated by conventional clean room technologies and 0.3% FWHM of a commercially available Si detector.
