Bhavya, a product designer, discusses the growing use of 3D printing in footwear manufacturing. He highlights the benefits of 3D printing for prototyping and customization, noting that companies like Zellefel in Germany are leading the way. Bhavya explains that 3D printing allows for more sustainable practices, using materials like TPU that are easily recyclable (up to 95%). He mentions that the cost of 3D printing shoes is currently around €70-€160, but expects it to decrease as the technology advances. Bhavya encourages aspiring designers to experiment with 3D printing, suggesting local Fab Labs as accessible resources.
