Combining　3D　printing　with　precursor-derived　ceramic　for　fabricating　electromagnetic　(EM)　wave-absorbing　metamaterials　has　attracted　great　attention.　This　study　presents　a　novel　ultraviolet-curable　polysiloxane　precursor　for　digital　light　processing　(DLP)　3D　printing　to　fabricate　ceramic　parts　with　complex　geometry,　no　cracks　and　linear　shrinkage.　Guiding　with　the　principles　of　impedance　matching,　attenuation,　and　effective-medium　theory,　we　design　a　cross-helix-array　metamaterial　model　based　on　the　complex　permittivity　constant　of　precursor-derived　ceramics.　The　corresponding　ceramic　metamaterials　can　be　successfully　prepared　by　DLP　printing　and　subsequent　pyrolysis　process,　achieving　a　low　reflection　coefficient　and　a　wide　effective　absorption　bandwidth　in　the　X-band　even　under　high　temperature.　This　is　a　general　method　that　can　be　extended　to　other　bands,　which　can　be　realized　by　merely　adjusting　the　unit　structure　of　metamaterials.　This　strategy　provides　a　novel　and　effective　avenue　to　achieve　＂target-design-fabricating＂　ceramic　metamaterials,　and　it　exposes　the　downstream　applications　of　highly　efficient　and　broad　EM　wave-absorbing　materials　and　structures　with　great　potential　applications.
