Online material configuration can expose a large photopolymer design space to users, but only if configuration is treated as engineering rather than as unrestricted combinatorics. This review develops a multivariable framework for configuring vat-photopolymerisation resins across five interacting axes: printing platform, viscosity state, cure-speed/reactivity target, colour/optical state and added functionality. The literature shows that resin composition, viscosity, curing kinetics and mechanical properties form coupled trade-offs, while pigments, fillers and functional additives can alter light attenuation, scattering, recoating, sedimentation and network formation [1–8]. Data-driven and active-learning studies further show that multiobjective optimisation can navigate such coupled spaces more efficiently than sequential one-variable- at-a-time selection [1–3]. A manufacturer implementation example is then analysed: the 3Dresyns online configuration corpus exposes printer selection, LV/HV branches, fast/intermediate/slow reactivity, a broad colour system, and four additional functionality slots drawn from more than 50 selectable functional entries. These choices are interpreted as configuration inputs, not universal compatibility claims. The proposed qualification workflow requires every materially changed configuration to re-establish its cure window, rheology, dimensional behaviour and application-specific performance before equivalence can be asserted.
