What Are 3D-Printed Sneakers and Why We Need Them?

Two of the most common issues people face every day are foot odor and discomfort. And that’s because of how traditional sneakers are designed. They have dense foam layers, sealed fabric, and glued construction, which leaves very little room for air to move through. This keeps the feet damp for hours, which is the ideal environment for bacteria to grow. 3D-printed sneakers were designed with this problem in mind. The open lattice design allows air to flow freely through the shoe, helping to prevent the build-up of moisture and keeping feet noticeably cooler throughout the day.

What are 3D-Printed Sneakers?

3D-printed sneakers are shoes made, partially or fully, using a 3D printer. 3D-printed sneakers are visually different due to the lattice structure. Instead of an all-foam midsole and a closed fabric upper, there are holes throughout the shoe in a grid pattern. Those spaces are what allow air to flow, moisture to escape, and the shoe to flex naturally with your foot. 

Common Materials Used in 3D-Printed Sneakers

The 3D-printed shoe materials directly influence key factors such as performance, durability, and breathability. Here are the commonly used materials:

• TPU (Thermoplastic Polyurethane): The most common material used in 3D printed footwear. It is flexible, recyclable, and easy to work with, but has weak interlayer bonding.
• Nylon (PA12): Nylon is stronger and more rigid than TPU.
• Resin-based materials: Used in high-precision printing methods such as DLP. It gives a finer surface detail and a more uniform structure.
• Polyurethane-urea: A newer material that is gaining ground in the industry. It has higher tear strength, more flex resistance, and stronger aging resistance. Nexbie uses this in their shoes, where independent testing showed a tear strength of 20 N/mm compared to 12–18 N/mm in most conventional footwear.

3D-Printing Technologies

Popular 3D printing technologies include FDM, SLA, DLP, SLS, & SLM. Most of them build a shoe point by point, line by line, which takes time and often leaves visible layer marks on the surface. Nexbie uses HALS low-release separation technology. Instead of printing the object layer by layer, they use dynamic light field technology to solidify the whole 3D object in one go. The whole shoe grows at the same time. That means that the print time is just two hours per pair, including post-processing, with a capacity of 300,000 pairs per month. The surface finish is also much cleaner.

What Problems Do 3D-Printed Sneakers Solve?

3D-printed sneakers solve the problems associated with traditional sneakers in a fundamentally different way of building a shoe. Here’s how:

• Breathability: The open lattice structure of 3D-printed sneakers creates natural airflow through the shoe. This allows air to move freely, and moisture escapes easily. 
• Non-Toxic Construction: Traditional shoes rely on solvent-based adhesives, PFAS coatings, and chemical dyes to hold everything together. 3D-printed sneakers are built as a single structure, which removes the need for most of those chemical inputs entirely.
• Durability: Most conventional shoes fall apart at the bond points. The single material structure of 3D-printed sneakers has no glued joints, which means it holds up significantly longer under daily use.
• Sustainability: 3D-printed sneakers made with a single material on demand simplify recycling.

Are 3D-Printed Sneakers Actually Worth It?

Yes, for most people. They last longer, breathe better, and are made without the chemical layers traditional shoes depend on. If you’re going to buy shoes and expect to have them for a while, 3D-printed ones are worth the switch.

Nexbie’s 3D-Printed Sneakers

Nexbie is one of the few brands actually building shoes differently. Every Nexbie 3D printed shoe goes through chemical qualification testing before it ships, and the construction process itself eliminates most of the toxic inputs traditional shoes depend on. If you’re looking for non-toxic, comfortable, and future-focused footwear, these are two of Nexbie’s most popular 3D printed sneakers.
