The invention provides particulate material suitable for use in manufacturing a three-dimensional object, the material comprising a plurality of particles. Each particle has a thermoplastic polymeric core; and a polymeric shell that coats the polymeric core. The polymeric core makes up 75 wt % or more of each particle. The polymeric shell is formed from a co-polymer of a major monomer and a minor monomer, wherein the major monomer comprises a polymerisable group, and the minor monomer comprises (i) a polymerisable group; and (ii) a functional component, and wherein the co-polymer is formed by reaction of the polymerisable group on the major monomer with the polymerisable group on the minor monomer.
A particulate material suitable for use in manufacturing a three-dimensional object, the material comprising a plurality of particles each of which has:
The particulate material of any one of the preceding claims, wherein the co-polymer comprises the minor monomer in an amount of:
The particulate material of any one of the preceding claims, wherein the polymeric core is selected from:
The particulate material of any one of the preceding claims, wherein the polymeric core makes up a proportion of the total weight of each particle that is:
The particulate material of any one of the preceding claims, wherein the major monomer makes up a proportion of the total weight of the co-polymer shell that is:
The particulate material of any one of the preceding claims, wherein the major monomer is a monomer that, when polymerised, has a Tg that differs from the Tm of the thermoplastic polymer that forms the polymer core by no more than 10° C.
The particulate material of any one of the preceding claims, wherein the major monomer comprises a polymerisable group selected from:
The particulate material of any one of the preceding claims, wherein the minor monomer comprises a polymerisable group selected from:
The particulate material of any one of the preceding claims, wherein the major monomer is isobornyl methacrylate or methyl methacrylate or alpha pinene methacrylate or ethyl methacrylate or 4-bromostyrene or 2,6-diphenylphenol or 4-chlorophenyl vinyl ketone.
The particulate material of any one of the preceding claims, wherein the polymeric core and the major monomer are selected from the following table:
The particulate material of any one of the preceding claims, wherein the major monomer is isobornyl methacrylate or methyl methacrylate or alpha pinene methacrylate or beta pinene methacrylate.
The particulate material of any one of the preceding claims, wherein the major monomer is isobornyl methacrylate and the polymeric core is PA-12.
A kit comprising two or more different particulate materials as defined in any one of the preceding claims, wherein the minor monomer includes a functional moiety that is a dye, and wherein each particulate material includes a dye that is a different colour.
