Vat photopolymerization (VPP) is an additive manufacturing method that requires the design of photocurable resins to act as feedstock and binder for printing parts, both monolithic composite. The a suitable photoresin costly time-consuming. development one formulation consumption kilograms materials, weeks performance testing, well need have developers with expertise knowledge materials used, making process cost thousands. This paper presents new characterization methodology acrylates allows computerization process, reducing timescale less than week. Okoruwa Maximum Saturation Potential (OMSP) uses attenuated total reflection (ATR-FTIR) study functional group acrylates, assigning numerical outputs characterize monomers, oligomers formulations, allowing more precise distinguishment between materials. It utilizes principles Gaussian normal distribution storage, recall, acrylate data without database numerous files spectral average coefficient determination (R2) 0.97. same can be used define potential reactivity formulations knowing components, something not possible when using properties such functionality. modifications made unknown prior their contents. Validation studies were performed boundaries operation OMSP assess methodology’s reliability tool. confidently detect changes caused by presence various system distinguish viscosity compare digitally mixed physically provides high degree accuracy (R2 0.9406 0.9964), highlighting future building foundations artificial intelligence in VPP; streamlining design; transforming way are characterized, selected, used.

Abstract Stereolithography (SLA) as one of the additive manufacturing processes provides new approaches towards high design flexibility and fast prototyping. In last years, variety different resins is highly enhanced polymers that meet requirements – mechanical, optical thermal properties well electroconductivity. To our knowledge, direct electroplating not investigated so far. The aim work development a composite material able to be processed by stereolithography electroconductivity for electroplating. Direct improves process on because less steps avoidance toxic chemicals. With regard efficiency saving resources, may more environmental than established industrial polymers. A commercially available synthetic resin base material. Electroconductive filler are graphitic particles with shapes sizes. By varying additives content, effects homogeneity viscosity resin, its hardenability electrical resistance manufactured samples investigated.
