A method of making a cutter structure comprising the steps of: placing a pre-formed body of hard material having a surface topography in a canister; placing an aggregated mass of grains of superhard material having a Vickers hardness of at least 25GPa into the canister over the surface of the body of hard material having the surface topography, placing a punch in contact with the aggregated mass of grains of superhard material, the punch having a surface with a surface topography inverse to the surface topography of the hard material body, the surface topography of the punch imprinting a pattern in the aggregated mass of grains of superhard material complementary to the surface topography of the punch and corresponding to the surface topography of the body of hard material, the surface of the punch in contact with the aggregated mass of grains of superhard material being formed of a ceramic material that does not react chemically with the superhard material and/or a sinter catalyst material for the grains of superhard material, the ceramic material being formed of any one or more of the group of oxide ceramic materials comprising magnesia, calcia, zirconia, and/or alumina, the method further comprising: subjecting the aggregated mass of grains of superhard material, the punch and the body of hard material to a pressure of greater than 3 GPa in the presence of the sinter catalyst material for the grains of superhard material at a temperature sufficiently high for the catalyst material to melt, sintering the grains to form the cutter structure comprising a layer of polycrystalline superhard material bonded to the body of hard material and having a surface topography corresponding to the surface topography of the hard material body and complementary to the surface topography of the punch; removing the cutter structure from the canister; and removing the punch from the layer of polycrystalline superhard material. placing a pre-formed body of hard material having a surface topography in a canister; placing an aggregated mass of grains of superhard material having a Vickers hardness of at least 25GPa into the canister over the surface of the body of hard material having the surface topography, placing a punch in contact with the aggregated mass of grains of superhard material, the punch having a surface with a surface topography inverse to the surface topography of the hard material body, the surface topography of the punch imprinting a pattern in the aggregated mass of grains of superhard material complementary to the surface topography of the punch and corresponding to the surface topography of the body of hard material, the surface of the punch in contact with the aggregated mass of grains of superhard material being formed of a ceramic material that does not react chemically with the superhard material and/or a sinter catalyst material for the grains of superhard material, the ceramic material being formed of any one or more of the group of oxide ceramic materials comprising magnesia, calcia, zirconia, and/or alumina, the method further comprising: subjecting the aggregated mass of grains of superhard material, the punch and the body of hard material to a pressure of greater than 3 GPa in the presence of the sinter catalyst material for the grains of superhard material at a temperature sufficiently high for the catalyst material to melt, sintering the grains to form the cutter structure comprising a layer of polycrystalline superhard material bonded to the body of hard material and having a surface topography corresponding to the surface topography of the hard material body and complementary to the surface topography of the punch; removing the cutter structure from the canister; and removing the punch from the layer of polycrystalline superhard material. subjecting the aggregated mass of grains of superhard material, the punch and the body of hard material to a pressure of greater than 3 GPa in the presence of the sinter catalyst material for the grains of superhard material at a temperature sufficiently high for the catalyst material to melt, sintering the grains to form the cutter structure comprising a layer of polycrystalline superhard material bonded to the body of hard material and having a surface topography corresponding to the surface topography of the hard material body and complementary to the surface topography of the punch; removing the cutter structure from the canister; and removing the punch from the layer of polycrystalline superhard material.
