Melt Electrowriting of Nylon‐12 Microfibers with an Open‐Source 3D Printer
Melt-electrowriting printer built on the open-source MEWron platform (a converted Voron 0.1 3D printer), with a heated flat or cylindrical collector for printing nylon-12 microfibres and tubes.

How hard this is to adopt
3.5 of 5, higher is easierEach score is shown against the range the other 59 builds actually occupy, because no criterion uses the full 1–5 scale. These describe how reproducible the build is, not how good the science is.
Resolution
4/1–5Smallest feature/positioning evidence about 33 µm.
Throughput
3/2–5Throughput not explicit; assigned moderate default.
Parts sourcing
3/2–4Mix of common parts and custom/printed components.
Skill needed
4/2–4Build/operation described as low-skill or basic assembly.
Facilities needed
3/2–4Requires accessible but nontrivial lab/maker equipment.
Documentation
3/2–5Some open documentation or files are available.
Validation effort
4/2–4Validation includes standards, benchmarking, replicates, or multi-condition tests.
Cycle time
4/1–4Speed evidence suggests rapid, real-time, or automated operation.
2 further criteria are recorded but not shown
- Application Level — scored 4 (75% of records share one value), so it cannot separate one build from another.
- Build Time (scored for only 6 of 60 records), so it cannot separate one build from another.
Both remain in the published dataset.

Abstract
This study demonstrates how either a heated flat or cylindrical collector enables defect-free melt electrowriting (MEW) of complex geometries from high melting temperature polymers. The open-source "MEWron" printer uses nylon-12 filament and combined with a heated flat or cylindrical collector, produces well-defined fibers with diameters ranging from 33 ± 4 to 95 ± 3 µm.

Perspective and practical signals
Why it matters
Extends open-source melt electrowriting beyond low-melting polymers such as PCL to nylon-12, producing well-defined fibres 33–95 µm in diameter on flat and tubular collectors.
Limitations
The cylindrical collector heats less efficiently than the flat collector, and annealing makes printed nylon-12 markedly more brittle.
