A failed 3D print typically goes straight to the trash with a tangle of plastic filament, a misshapen object or a handful of scraps that no longer feel useful.
asserted
that → fail → scraps
For Davis, they were raw material, waiting for another chance.
asserted
they → wait → chance
The Massachusetts high school student spent hundreds of hours developing a small recycling system to convert discarded 3D-printing plastic into usable filament.
asserted
student → spend → filament
His invention addressed a growing waste problem and won him $75,000 at one of the world’s largest science competitions, states an online report by the Society for Science.
asserted
report → address → Science
Recycling plastic scraps into filament
Davis, a student at Bishop Feehan High School in Attleboro, Massachusetts, built the machine as part of his science research project.
asserted
Davis → recycle → project
The system uses waste plastic, including waste generated during 3D printing and converts it into filament that can again be fed into a 3D printer.
asserted
that → use → printer
The process could let users recycle material from failed prints and other plastic waste instead of buying new filament over and over again.
uncertain
users → let → filament
The invention uses two methods of processing plastic: pultrusion and extrusion.
asserted
invention → use → plastic
The Society for Science reported that Davis developed a system that was roughly 45 percent more efficient than using the existing approaches separately.
asserted
that → report → approaches
The machine was also meant to be used practically.
asserted
machine → mean → ?
It is designed to produce higher quality recycled filament and is relatively easy to operate, adds the report.
asserted
report → design → filament
Davis’s design costs about 90% less than recycling machines on the market, potentially making small-scale plastic recycling more accessible to schools, hobbyists and individual 3D-printer users.
asserted
recycling → cost → schools
The secret waste of 3D printing
The project deals with a problem that is easily overlooked.
asserted
that → deal → problem
3D printing is now a common technology in classrooms, homes, labs and workplaces but the creation of an object often involves more plastic than the finished product suggests.
uncertain
product → involve → plastic
Failed prints and supports and leftover filament can build up quick.
asserted
prints → fail → ?
The Society for Science cites information that states that up to 67% of the filament in a regular 3D-printing project becomes waste.
asserted
% → cite → project
Instead of treating them as disposable, Davis’s machine is designed to put those scraps back into the cycle of production.
asserted
machine → treat → production
That idea is part of a larger push toward more sustainable manufacturing, in which materials are collected and reused rather than constantly replaced by new ones.
asserted
materials → collect → ones
Over 800 hours of experimentation
Getting the machine to work was not straightforward.
asserted
machine → get → experimentation
Davis put in over 800 hours on the project, went through over 50 iterations of the components, and did several large redesigns.
asserted
Davis → put → redesigns
Each version gave him another opportunity to fine-tune the system and work out problems with the recycling process.
asserted
version → give → process
Eventually, the project was taken to the 2025 Regeneron International Science and Engineering Fair (ISEF) in Columbus, Ohio, where Davis competed against other young researchers from around the world.
asserted
Davis → take → world
Acknowledgment of $75,000
Davis snagged a $75,000 Regeneron Young Scientist Award and was runner-up in the competition’s top award category at the 75th annual ISEF.
asserted
Davis → snag → ISEF
Not only was his project notable for recycling plastic, but it also
asserted
it → recycle → plastic
It's also desktop-sized, hinting at a future where recycling could happen closer to where plastic waste is created, instead of requiring users to mail material to a large industrial facility.
uncertain
waste → size → facility
The next step for Davis
The award was another prod for Davis to continue exploring in the field.
asserted
Davis → continue → field
His work in plastic recycling and extrusion has made him more interested in advanced manufacturing and mechanical and materials engineering.
asserted
him → make → manufacturing
Those interests could affect his studies when he goes off to college.
uncertain
he → affect → college
For now, his invention presents a simple but potentially powerful idea: the plastic waste from a 3D printer doesn’t have to be the end of the story.
asserted
waste → present → story
