In 1827, the British Handbook of Trades summed up the occupation of the shoemaker: "Few trades are more useful, and few more profitable than the cobbler
.
Like Adidas and New Balance, shoes are now produced with the help of additive manufacturing materials and systems
.
The shoe responds to the overwhelming interest in runners, and voxeljet points to three challenges in the footwear industry that the product addresses:
Personalization, where customers emphasize the value of custom-made shoes that perfectly adapt to their feet and movements for improved comfort and performance;
●Sustainable development, the market requires the use of materials that are easier to recycle;
●Automation, through which small batches of products that once required special tools or molds can be produced economically
.
As readers know, additive manufacturing solves these problems with ease, making the technology and its users the newest shoemaker in the world
.
The Coral Runner emphasizes innovation and customizability with a design inspired by coral
.
Shun Ping Pek explained: "The biggest advantage of 3D printing is that it can both be manufactured on demand and transfer a digital model to a real object one-to-one, although it is theoretically possible to use traditional production techniques such as injection molding.
Manufactured, but that's going to be very challenging because of the consistency of the design
.
The shoe's TPU material comes from material manufacturer Covestro, which has been a common material for shoe soles for decades
.
TPU can be very soft and stretchy or very hard and durable, and voxeljet's HSS technology can affect these properties in all three dimensions
.
This property definition is achieved by so-called grayscale printing
.
By specifically controlling the volume of absorbent sprayed into the powder bed, specific build areas can be dyed deeper
.
The more absorbent sprayed, the stronger the part
.
By using industrial inkjet printheads, different shades of gray can be printed in one layer, creating different product characteristics in each layer
.
So, returning to the spirit of craftsmanship, shoemakers, although relatively few in number, are still customizing shoes for us
.
Additive manufacturing allows soles to perfectly adapt to individual stepping patterns and cushioning requirements
.
Assessing wall thickness is one of the biggest challenges to ensure the shoe has sufficient flexibility while reducing weight and required materials
.
However, this challenge was quickly overcome with quick digital tweaks to the design and subsequent 3D printing
.
voxeljet is already working on extending the HSS process to the VX1000 HSS, a 3D printing system that has demonstrated advantages especially in high-volume production to fully automated series production
.
The system combines the customizability of old-fashioned shoe production with the mass production models of twentieth-century consumerism
.
The future may be now, but examples from the past create exciting prospects for design and manufacturing in this young century
