Mobile Espresso Bike and 3D-Printed Coffee Cups: Sustainable Cafe Tech

Looking for coffee on the go usually means grabbing a paper cup from a chain — but what if your espresso came from a custom-built bike or a cup printed just for you? Around the world, designers and engineers are reimagining how we make, serve, and drink coffee, combining craftsmanship, sustainability, and mobility. These aren’t commercial ventures (yet), but real experiments pushing what’s possible with today’s tech.

The big idea? A mobile espresso bar powered by pedaling and a set of 3D-printed ceramic cups made one per day — both are real projects tackling waste, energy, and accessibility in fresh ways.

Bernat Cuni’s One Cup a Day: 3D-Printed Ceramics for Coffee

Spanish designer Bernat Cuni launched his “One Cup a Day” project using cutting-edge 3D ceramic printing technology. Each cup was digitally modeled and then printed in ceramic material, transforming what were once just design models into real, functional (or semi-functional) objects. While not every cup was practical for daily use, the diversity in form and the immediacy of production showed how this tech could revolutionize how we think about single-use or personalized coffee ware.

The key takeaway? 3D ceramic printing allows rapid prototyping and production of unique, customized cups — offering both aesthetic value and potential environmental benefits by reducing mass-produced waste.

Velopresso: A Bicycle-Powered Espresso Maker from London

Across the continent in London, Royal College of Art students Amos Field Reid and Lasse Oiva combined two of their passions — cycling and coffee — into Velopresso, a fully mobile espresso setup built onto a bicycle. The innovative design includes a modified hand-cranked grinder linked directly to the bike’s chain: pedal just five times and you’ve ground enough coffee for a double espresso.

The heat source currently comes from an outdoor camping stove, but the duo is actively experimenting with using spent coffee grounds as fuel — turning waste into energy. This grassroots approach to mobile brewing proves that with creativity and passion, you can craft quality espresso almost anywhere, using minimal resources.

Why These Projects Matter for Sustainable Coffee Culture

Both the 3D-printed cup initiative and the Velopresso bike reflect growing trends in sustainable, mobile, and design-forward coffee solutions. While neither is available for mass purchase, they highlight the potential for reducing waste, using renewable energy, and creating more personalized coffee experiences. These aren’t just art projects — they’re blueprints for the future of mobile and eco-conscious coffee service.

Frequently Asked Questions

What is the “One Cup a Day” project by Bernat Cuni?

Bernat Cuni, a Spanish designer, created a project where he designed and 3D-printed one unique ceramic coffee cup per day using advanced ceramic printing technology. The project demonstrated the flexibility and speed of 3D printing in producing customized, functional, or artistic cups, even if not all were practical for everyday use.

How does the Velopresso bike-powered espresso maker work?

Velopresso is a mobile espresso bar built onto a bicycle by two London designers. It features a hand-cranked grinder connected to the bike chain — pedal five times to grind coffee for a double espresso. The current heat source is an outdoor stove, but the team is testing used coffee grounds as a sustainable fuel alternative.

Are the 3D-printed cups from Cuni’s project available for purchase?

Not officially. The “One Cup a Day” cups were part of an experimental design project showcasing the potential of 3D ceramic printing, and while some may have been produced as prototypes or limited editions, they were not released as a commercial product line.

Is Velopresso available to the public or in production?

No, Velopresso is not a commercial product. It was developed as a passion project by two Royal College of Art students to explore mobile, human-powered coffee brewing. It remains a prototype and proof-of-concept for sustainable, on-the-go espresso making.

What kind of fuel does Velopresso use?

Currently, Velopresso uses a traditional outdoor camping stove for heat. However, the creators are experimenting with using leftover coffee grounds — the spent coffee from the espresso brewing process — as a renewable fuel source to make the entire setup more sustainable.

Can 3D-printed ceramic cups really replace traditional coffee cups?

While not designed to fully replace mass-produced cups, 3D-printed ceramic cups offer a customizable, potentially more sustainable alternative. They can reduce reliance on generic, throwaway cups and allow for unique designs, though their adoption depends on scalability and cost-efficiency in production.
