PETFusion 2.0 - Recycle PET Bottle into 3D Printing Filament
PETFusion 2.0 is an all-in-one machine that turns standard PET water bottles into 1.75mm printing filament. It cuts the bottle into strips, melts the strips through 3 heated hotends, optionally colorizes the output, and welds individual strands into continuous spools.
Every structural component is 3D-printable. The non-printable hardware costs around $114 on AliExpress, with direct buying links provided in your download.
Funded in 3 hours on Kickstarter. Backed by 800+ makers worldwide. PETFusion 2.0 is the sustainability machine the maker community asked for, refined across 15+ design revisions in real workshops.
Print from bottles, not spools.

✓Can you actually build this? Yes.
Four months of our work, condensed into yours.
Our Kickstarter backers paid roughly the same price you do. You are getting the work we put in, so you do not have to.
Key features
How it works
Printer requirements
We built PETFusion to stop buying filament.
Filament prices kept climbing. Bottles kept ending up in our recycling bin. We thought, why are we paying $30 for plastic we are already throwing away? So we built a machine to fix that.
Then 800+ backers said they wanted one. We rebuilt the design 15 times based on what they reported from their workshops. The price you pay is roughly what they paid. We are not marking up the work, we are just sharing the result.
What makers are saying
Built it from local Kirkland water bottles my office throws out. Hits 1.75mm output pretty consistently now after I dialed in the temp on the second hotend. The colorizer is way more fun than I expected.
Print quality is better than the cheap recycled spools I was buying off Amazon. Took a weekend to build, the assembly video is honest about which steps are easy and which need patience.
Sourcing the worm gear motor took a while in the UK, ended up paying twice the AliExpress price. But the design itself works as advertised. Made about 8 spools of bottle filament so far. Kids love watching it run.
I had wiring questions and the team responded the same day. The welder module is the highlight, lets me chain multiple bottles into one spool without splices. Big quality jump from PETFusion 1.0.
Got the commercial license and run a small recycling stand at our local maker fair. People love watching bottles turn into filament live. Pays for itself in about 6 weekend events.
emailing us
You probably won't even need our help.
We over-document everything. The 75-minute video shows every cut, every wire, every temperature setting. The BOM has photos and direct links. Crimp connectors only, color-matched.
Most makers finish without sending us a single email. That's the goal. But if you do hit a snag, info@creative3dp.com, real human, usually same day.
