The development of 3D technology has brought opportunities and challenges to the footwear industry because people’s living standards have been improving due to economic development, and people have higher requirements for the design of fashion shoes and boots. The use of 3D printing technology in the design of fashion shoes and boots can enable faster molding of footwear products, enrich the shape of footwear, and meet people’s aesthetic needs for fashion shoes. In this paper, we firstly describe the advantages of 3D printing molding shoe models and then use 3D laser foot scanning and measuring instrument to scan and obtain the cloud map of shoe lasts and foot-related data. Secondly, we realize the digital management of shoe lasts by establishing the database of solid models. On this basis, we apply the technology of least squares support vector machine improvement algorithm to make partial modifications to the lasts according to the need to leave the appropriate helper and foot lining degrees. Finally, based on this technology, we apply the least squares support vector machine improvement algorithm technology to make partial modifications to the last shape according to the need for appropriate helper and foot lining degrees to realize the process of shoe last redesign. The last model and role model can also be produced by 3D printing technology, which can be used as a mold to facilitate the processing of the cut last 2D unfolding material for shoe and boot production later. Therefore, the article studies and analyzes the design and manufacturing process of digital shoe lasts based on individual foot shape and uses CAD/CAM technology to realize the digitalization of shoe last design.

“…This need has motivated research into the behaviour of 3D printed materials in various loading states. Recent studies have investigated the ability of the 2D honeycomb structure to absorb energy in compression (Bates et al, 2016(Bates et al, , 2018, characterised 3D printed TPMS-based infill patterns in uniaxial compression (Abueidda et al, 2019;Podroužek et al, 2019) and investigated the ability to print custom shoe-insoles with varying mechanical properties through tailored 3D infill pattern design (Amorim et al, 2019). Podrouzek et al compared the behaviour of different 3D infill patterns in compression (Podroužek et al, 2019), while Wang et al compared one 3D infill patterngyroid infillto two common 2D infill patterns for energy absorption through the finite element method (Wang et al, 2020).…”

Purpose Most support surfaces in comfort applications and sporting equipment are made from pressure-relieving foam such as viscoelastic polyurethane. However, for some users, foam is not the best material as it acts as a thermal insulator and it may not offer adequate postural support. The additive manufacturing of such surfaces and equipment may alleviate these issues, but material and design investigation is needed to optimize the printing parameters for use in pressure relief applications. This study aims to assess the ability of an additive manufactured flexible polymer to perform similarly to a viscoelastic foam for use in comfort applications. Design/methodology/approach Three-dimensional (3D) printed samples of thermoplastic polyurethane (TPU) are tested in uniaxial compression with four different infill patterns and varying infill percentage. The behaviours of the samples are compared to a viscoelastic polyurethane foam used in various comfort applications. Findings Results indicate that TPU experiences an increase in strength with an increasing infill percentage. Findings from the study suggest that infill pattern impacts the compressive response of 3D printed material, with two-dimensional patterns inducing an elasto-plastic buckling of the cell walls in TPU depending on infill percentage. Such buckling may not be a beneficial property for comfort applications. Based on the results, the authors suggest printing from TPU with a low-density 3D infill, such as 5% gyroid. Originality/value Several common infill patterns are characterised in compression in this work, suggesting the importance of infill choices when 3D printing end-use products and design for manufacturing.

“…With recent advances in consumer grade 3D printers, end users without professional skills are able to fabricate various objects from a smartphone case to custom mechanical tools. Along with the progress of machinery, there has been a growing desire for multi-color and multi-material 3D printing using fused deposition modeling (FDM), not only to get an artifact aesthetically appealing but also to enable the production of an object with properties not found in nature, i.e., metamaterials, even when faced with a limited choice of materials (e.g., [1,2,9]). However, the materials used in low-cost 3D printers are fairly limited due to the form factor and affordability.…”
