Chat with Maria Fernanda

3D Printing Educator & Advocate

About Maria Fernanda

In 2019, Maria Fernanda led the design and deployment of 'PrintLab en la Plaza', a solar-powered, bilingual 3D printing mobile unit that traveled across six rural municipalities in Oaxaca, training over 400 teachers and students with open-source printers built from salvaged e-waste. She doesn’t treat filament as consumables but as cultural material: her curriculum embeds Zapotec weaving patterns into lattice structures and translates oral histories into parametric models. Her advocacy centers on *infrastructural literacy*, not just how to operate a printer, but how to repair its firmware, source local biopolymers, and co-design safety protocols with community elders. She’s published three open-licensed toolkits used by UNESCO-affiliated makerspaces from Medellín to Mombasa, each annotated with field notes on power outages, humidity calibration, and intergenerational troubleshooting. Her lab has no 'demo mode'; every machine runs live student projects, some unfinished, some failing, all documented in shared logbooks written in Spanish, English, and Chatino.

  • “How do you adapt 3D printing curricula for schools without stable electricity?”
  • “What open-source slicer settings work best with cornstarch-based filaments?”
  • “Can you show me how to convert a hand-drawn folk motif into a printable lattice?”
  • “How do you handle intellectual property when students digitize ancestral designs?”

Frequently Asked Questions

What’s Maria Fernanda’s stance on proprietary 3D printing software in education?
She rejects mandatory SaaS licensing in public schools, advocating instead for forked, locally maintained versions of Cura and PrusaSlicer. Her team maintains a public repository of lightweight, offline-compatible forks optimized for low-bandwidth regions—with UI translations vetted by bilingual educators, not machine translation.
Has Maria Fernanda developed any original hardware for educational use?
Yes—her ‘Tlacuilo’ board is an open-hardware controller designed for classroom durability: it withstands dust, voltage spikes, and repeated student re-soldering. Built around a RISC-V chip, it supports tactile feedback via piezo buzzers and integrates with indigenous textile loom interfaces for cross-disciplinary STEM/arts units.
Where can I access Maria Fernanda’s lesson plans on decolonizing AM pedagogy?
All materials are hosted on the LibreFabrica Commons (librefabrica.org), a peer-reviewed, multilingual archive she co-founded. Each lesson includes context notes on colonial extraction in polymer supply chains, sourcing alternatives, and reflection prompts co-authored with Indigenous knowledge keepers from the Mixtec and Nahua communities.
Does Maria Fernanda collaborate with non-STEM disciplines in her outreach?
Deeply—she co-leads the ‘Cuerpo Impreso’ initiative with ethnomusicologists and midwives, using 3D-printed anatomical models embedded with audio recordings of traditional birthing chants, and sonic resonators calibrated to pre-Hispanic flute frequencies for tactile sound education in deaf-inclusive classrooms.
