NASA-Grade Filament? Tullomer Promises Aerospace Strength for Desktop Printers

Overview

A new filament is making waves: Tullomer, a crystalline super-polymer claiming ultra-low outgassing and strength rivaling PEEK and metal—all at a lower weight. Here’s why it’s catching attention in the 3DnMe community.

✅ What Makes It Special?

Ultra‑low outgassing: Lab tests show Tullomer outperforms PEEK in UHV environments—in some cases reaching the detection limit on residual gas analysis dynamism.com+15dynamism.com+15all3dp.com+15.
High strength & crystallinity: Its aligned molecular structure gives it metal-like stiffness, chemical resistance, and thermal stability up to ~200 °C dynamism.com+1z-polymers.com+1.
Lightweight alternative: About half the density of aluminum, yet mechanically comparable—ideal for aerospace and industrial parts hackaday.com+2all3dp.com+2production-to-go.com+2.

🤔 Should You Try It?

Factor	Likely ✅	Possibly ❌
Printer compatibility	High-temp or chambered printers like Bambu X1E can handle Tullomer pixelsquid.com+15dynamism.com+15dynamism.com+15. <br> – Low-end machines may struggle—print settings and adhesion need tweaking. \| X1C can print it, but success depends on tuning .
Cost vs Performance	Great for vacuum, aerospace, or chemically demanding parts.	At ~$500/kg, it’s pricey and early adoption risks. \|
User feedback	Limited early tests show promise. Hackaday and All3DP praise its chemical resistance and strength .	Some users on Reddit and YouTube report layer adhesion struggles—“manufacturer couldn’t print acceptable layer adhesion” .

🎯 3DnMe Take: Should You Care?

For standard prints or hobby use, it’s overkill. But if you’re targetting:

Vacuum-safe prototypes,
Lightweight structural parts,
Chemical-resistant or high‑temp applications,

then Tullomer could be worth exploring—especially if you have the printer setup to handle it.

🔧 Technical Specs & Printer Fit

Nozzle: 275–300 °C
Bed: ~120 °C
Layer height: ~0.05 mm for fiber alignment
Speed: Up to 500 mm/s
Environment: Enclosed chamber (≥60 °C) improves Z-layer bonding dynamism.com+1z-polymers.com+1ensingerplastics.com+5z-polymers.com+5fabbaloo.com+5

If your machine runs hotter and prints slowly with strong adhesion tools (like Magigoo PC), it’s worth experimenting.

🚀 Final Thoughts

Tullomer is pushing 3D‑printed plastic into performance tiers once reserved for PEEK or aluminum—but it isn’t a no-brainer. For niche, high‑value applications, it’s compelling. For everyday use, it’s a bit wild.

Recommendation: If you’re on a Bambu X1E/X1C with a heated chamber and work in vacuum, aerospace, or chemical handling, grab a small spool and test prints. Let community feedback build on that—Tullomer’s strengths are real but need more field validation.
