What's On
From hands-on workshops to inspiring talks and live demos, SMRRF 2026 was packed with creativity, community, and cutting-edge 3D printing. Whether you're a seasoned maker or just starting out, there was something for everyone, including talks, workshops, giveaways, a fundraising raffle, and powerful stories from neurodivergent voices in STEM.
Voron 2 Serial 0 Raffle Total Raised: $11,825
Together, the community raised $11,825 through the Voron Serial 0 charity raffle for the Sanjay Mortimer Foundation.
​
This development frame, known as Serial 0, is the machine on which the entire VORON 2 line was created. First built as a VORON 2.0 prototype in 2017, it went on to serve as the test platform for every major release: V2.1, V2.2, and V2.4. All of the V2 development took place on this frame, making it one of the most historically significant objects in the VORON ecosystem.
​
Now, this legendary machine is being restored by Steve Peterson, who will rebuild it with fresh components while preserving the original Serial 0 frame and as many authentic elements as possible. Follow Steve as he rebuilds the VORON 2, serial 0 on his YouTube channel.
SMRRF Auction 2026 Total Raised:
£10,227

SMRRF RAFFLE 2026 Total Raised:
£5,520
The SMRRF 2026 raffle was another fantastic success, raising £5,520 for the Sanjay Mortimer Foundation.
​
Thanks to the generosity of our sponsors and community, visitors had the chance to win a range of incredible prizes from across the 3D printing ecosystem.
​
Every ticket purchased helped support the Foundation’s mission to empower neurodivergent young people through engineering, making and STEM education.
Death Racers
One of the most exciting moments of SMRRF 2026 was the return of Death Racers, the chaotic and crowd-favourite battle arena created by Michael Baddeley and Sam Prentice.
​
Competitors brought their own 3D-printed machines to the arena, racing, colliding and battling for survival in front of a packed audience. The event captured the creativity, humour and engineering spirit that defines the global RepRap community.
​
Designed to be printed, built and customised by makers, Death Racers has become a recurring highlight at RepRap festivals around the world.​

Meet Our STARS
Our SMF Stars are the beating heart of SMRRF and the reason we do what we do. These brilliant young minds, many navigating the challenges of autism, ADHD, or dyslexia, bring extraordinary talent, creativity, and resilience to the world of STEM.
This year, they’ll take to the stage to share their journeys, reminding us all why inclusion, innovation, and community matter.​
Interested in sponsoring one of our Stars? Our applications are open.
Workshops
We're planning a ton of exciting workshops for kids, and for the big kids among us too!
Get ready to build, make, test, and try new things that spark curiosity and creativity in makers of all ages.
​
Whether you're designing, tinkering, or simply exploring, there’s something for everyone to get stuck into.​ More information on our workshop page. Please see below for our Workshops schedule.
