The subsequent step involves <strong>creating a 3D model of both the shoe sole and the upper, tailored around the digital last<\/strong>. In the footwear industry, the widely utilized software for this purpose is Rhinoceros, known for its surface-based modeling capabilities that provide remarkable flexibility in shaping complexity and offering innovative functions.<\/p>\n\n\n\n<p class=\"has-medium-font-size\"><strong>Modeling a sole in 3D is indeed a multifaceted challenge<\/strong>, necessitating specific expertise and a strategic approach to encompass all the technical requirements and organic forms inherent in the process. <strong>Arsutoria <\/strong>(Milan based footwear professional school) <strong>bring forth their extensive experience in the field,<\/strong> showcasing to Bulla the full spectrum of possibilities and potentialities of Rhinoceros in shoe technical design.<\/p>\n\n\n\n<p class=\"has-medium-font-size\">When considering the manufacturing process of footwear, a crucial aspect to highlight is the integration of Direct3D technology, particularly in the production of soles. Bulla empowered the company\u2019s technological prowess to significantly enhance the 3D printing of flexible components, for applying it to the soles design for this project.<\/p>\n\n\n\n<p class=\"has-medium-font-size\"><strong><strong>Direct3D manufactures and delivers small, lightweight and cost-effective Pellet Extruders and 3D Printers. <\/strong><\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"main-advantages-of-using-pellets-instead-of-filament-are\"><strong><strong>Main advantages of using pellets instead of filament are:<\/strong><\/strong><\/h2>\n\n\n\n<p class=\"has-medium-font-size\">\u2022 Wider selection of materials, including very soft TPEs and MIM feedstock<\/p>\n\n\n\n<p class=\"has-medium-font-size\">\u2022 Higher productivity, ideal for mid size parts<\/p>\n\n\n\n<p class=\"has-medium-font-size\">\u2022 Lower printing costs<\/p>\n\n\n\n<p class=\"has-medium-font-size\">\u2022 In-line colouring<\/p>\n\n\n\n<p class=\"has-medium-font-size\">Conversely, when addressing the production of the upper part of the shoe, Sneaknit has contributed with its specialized expertise in 3D knitting.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"about-matteo-bulla\"><strong><strong><strong><strong><strong>About Matteo Bulla<\/strong><\/strong><\/strong><\/strong><\/strong><\/h2>\n\n\n\n<p class=\"has-medium-font-size\">Matteo Bulla, 26 years old, is an Industrial designer.

However, the sustainability of the digital process is compromised by gluing the sole, rendering the shoe non-disassemblable and non-recyclable. Therefore, it\u2019s imperative not to use glue for the sole and upper assembly to exploit the efficient and sustainable soul of the digital footwear design process.<\/p>\n\n\n\n<p class=\"has-medium-font-size\">As a consequence the design concept focuses on combining 3D knitted canals with a diverse range of 3D printed shapes to securely fasten the upper to the sole using laces that wrap around the shoe.

This alignment, in turn, relies on the placement of the holes and the inclination of the tie rods. In this scenario, they structured the design around a pre-made upper (Made in iCad3D+) that featured six eyelets. <\/p>\n\n\n\n<p class=\"has-medium-font-size\">These eyelets are situated closer to the toe area compared to typical shoes, as the tie rods need to uniformly encase the entire foot. Following that, it is crucial to set the positioning of the holes that were first set on the lateral side of the shoe to then pinpoint the positioning on the medial (Internal) ones.<\/p>\n\n\n\n<p class=\"has-medium-font-size\">Once the positioning of the tie rods on both sides has been determined, it becomes crucial to comprehend how they translate into a three-dimensional form. Therefore, the subsequent step involved projecting the flat lines onto the upper through the help of Rhinoceros. <\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-5 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"511\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" data-src=\"https:\/\/shoestechnologies.exum.eu\/wp-content\/uploads\/2024\/06\/Picture-8-1024x511.png\" alt=\"\" class=\"wp-image-21795 lazyload\" title=\"\" data-sizes=\"auto\" data-srcset=\"https:\/\/shoestechnologies.exum.eu\/wp-content\/uploads\/2024\/06\/Picture-8-1024x511.png 1024w, https:\/\/shoestechnologies.exum.eu\/wp-content\/uploads\/2024\/06\/Picture-8-300x150.png 300w, https:\/\/shoestechnologies.exum.eu\/wp-content\/uploads\/2024\/06\/Picture-8-768x383.png 768w, https:\/\/shoestechnologies.exum.eu\/wp-content\/uploads\/2024\/06\/Picture-8-1100x549.png 1100w, https:\/\/shoestechnologies.exum.eu\/wp-content\/uploads\/2024\/06\/Picture-8-600x300.png 600w, https:\/\/shoestechnologies.exum.eu\/wp-content\/uploads\/2024\/06\/Picture-8-20x10.png 20w, https:\/\/shoestechnologies.exum.eu\/wp-content\/uploads\/2024\/06\/Picture-8.png 1516w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Outline of the lines where the canal must begin and end their path.<\/figcaption><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\">\n<p class=\"has-medium-font-size\">Following this, a similar procedure was employed for<strong> delineating the lines where the canals should start and conclude their path<\/strong>. <\/p>\n<\/div>\n<\/div>\n\n\n\n<p class=\"has-medium-font-size\">Knowing how the tie rod flew on the 3D upper they could flatten to create a 2D file for the 3D knitting machine.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"sole-3-d-modeling-and-development\"><strong><strong><strong><strong>Sole 3D modeling and development<\/strong><\/strong><\/strong><\/strong><\/h2>\n\n\n\n<p class=\"has-medium-font-size\">In this phase Rhino proved to be the perfect software for sole modeling since Bulla has been able to achieve shape complexity and exploit his creativity while respecting the strict geometric constraints to respect in shoe design.&nbsp;<\/p>\n\n\n\n<p class=\"has-medium-font-size\">The shoe soles have been meticulously crafted using a specific methodology. <\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"635\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" data-src=\"https:\/\/shoestechnologies.exum.eu\/wp-content\/uploads\/2024\/06\/Picture-9-1024x635.png\" alt=\"\" class=\"wp-image-21807 lazyload\" title=\"\" data-sizes=\"auto\" data-srcset=\"https:\/\/shoestechnologies.exum.eu\/wp-content\/uploads\/2024\/06\/Picture-9-1024x635.png 1024w, https:\/\/shoestechnologies.exum.eu\/wp-content\/uploads\/2024\/06\/Picture-9-300x186.png 300w, https:\/\/shoestechnologies.exum.eu\/wp-content\/uploads\/2024\/06\/Picture-9-768x476.png 768w, https:\/\/shoestechnologies.exum.eu\/wp-content\/uploads\/2024\/06\/Picture-9-1100x682.png 1100w, https:\/\/shoestechnologies.exum.eu\/wp-content\/uploads\/2024\/06\/Picture-9-600x372.png 600w, https:\/\/shoestechnologies.exum.eu\/wp-content\/uploads\/2024\/06\/Picture-9-20x12.png 20w, https:\/\/shoestechnologies.exum.eu\/wp-content\/uploads\/2024\/06\/Picture-9.png 1253w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Rhino was essential in shaping the soles of Bulla&#8217;s shoes, combining complexity, creativity and respect for geometric constraints.<br><\/figcaption><\/figure>\n\n\n\n<p class=\"has-medium-font-size\">The process begins by delineating the <strong>lateral curves in a 2D environment<\/strong>, aligning them with the shoe&#8217;s <strong>silhouette <\/strong>and <strong>construction <\/strong>lines (<em>illustrated by the blue lines<\/em>). Subsequently, a<strong> corresponding 2D curve<\/strong> is sketched to <strong>outline the outsole <\/strong>(<em>depicted by the green lines<\/em>). <\/p>\n\n\n\n<p class=\"has-medium-font-size\"><strong>By employing the Crv2View command, <\/strong>a 3D curve is generated from the intersection of these two lines. Once the necessary 3D lines are obtained, surfaces are constructed using Sweep2, with these lines serving as rails. Another vital technique involves projecting the 2D curves onto the surface to accurately translate them into the 3D space.<\/p>\n\n\n\n<p class=\"has-medium-font-size\">Finally, they delve into the most distinctive aspect of the design. The pattern entails an alternating arrangement of \u201c<strong>K\u201d shaped and triangular concave shapes,<\/strong> intricately interlocking like pieces of a puzzle to accentuate the design. The incorporation of K-shaped concave forms directly correlates with the inclination of the tie rods, highlighting the interplay between functionality and visual appeal in the design.<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-6 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"555\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" data-src=\"https:\/\/shoestechnologies.exum.eu\/wp-content\/uploads\/2024\/06\/Picture-10-1024x555.jpg\" alt=\"\" class=\"wp-image-21788 lazyload\" title=\"\" data-sizes=\"auto\" data-srcset=\"https:\/\/shoestechnologies.exum.eu\/wp-content\/uploads\/2024\/06\/Picture-10-1024x555.jpg 1024w, https:\/\/shoestechnologies.exum.eu\/wp-content\/uploads\/2024\/06\/Picture-10-300x163.jpg 300w, https:\/\/shoestechnologies.exum.eu\/wp-content\/uploads\/2024\/06\/Picture-10-768x416.jpg 768w, https:\/\/shoestechnologies.exum.eu\/wp-content\/uploads\/2024\/06\/Picture-10-1536x832.jpg 1536w, https:\/\/shoestechnologies.exum.eu\/wp-content\/uploads\/2024\/06\/Picture-10-2048x1110.jpg 2048w, https:\/\/shoestechnologies.exum.eu\/wp-content\/uploads\/2024\/06\/Picture-10-1600x867.jpg 1600w, https:\/\/shoestechnologies.exum.eu\/wp-content\/uploads\/2024\/06\/Picture-10-1100x596.jpg 1100w, https:\/\/shoestechnologies.exum.eu\/wp-content\/uploads\/2024\/06\/Picture-10-600x325.jpg 600w, https:\/\/shoestechnologies.exum.eu\/wp-content\/uploads\/2024\/06\/Picture-10-20x11.jpg 20w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\">\n<p class=\"has-medium-font-size\">To create them, a <strong>4 mm offset<\/strong> from the base tie <strong>rod lines<\/strong> and the <strong>external perimeters<\/strong> of the shape was employed. <\/p>\n<\/div>\n<\/div>\n\n\n\n<p class=\"has-medium-font-size\">This meticulous adherence to the 4 mm measurement throughout the design process ensures consistency and coherence in the overall structure.<\/p>\n\n\n\n<p class=\"has-medium-font-size\">Once the whole structure was established, attention turned to designing the pattern of the Outsole.
