The Complete Guide to Choosing PLA, PETG, TPU, ASA, Carbon Fibre & More
Whether you've just unboxed your Bambu Lab A1 Mini, A1, P1P, P1S, X1 Carbon or H2D, choosing the right filament is one of the biggest factors affecting print quality, reliability and overall printing success.
One of the best things about Bambu Lab printers is that they're designed to work with a huge range of third-party 1.75mm filaments, giving you access to more colours, materials and finishes than ever before.
At Filamigo, we've tested and supplied thousands of spools of filament to Australian makers. In this guide, we'll explain which materials perform best, which are compatible with the AMS, and how to choose the perfect filament for your next project.
🤔 Do You Need to Buy Bambu Lab Filament?
No.
This is probably the biggest myth in 3D printing.
Bambu Lab printers are designed to print with quality third-party filament, provided the correct material profile is selected.
Many experienced makers regularly use premium brands like ZIRO, alongside other well-known manufacturers, to achieve outstanding results.
What matters most is:
✅ Consistent filament diameter
✅ Good spool winding
✅ Dry filament
✅ Correct print profile
✅ High manufacturing quality
Choosing quality filament often has a bigger impact on print quality than simply choosing a particular brand.

🌈 PLA – The Best Filament for Most Bambu Lab Owners
If you're wondering which filament to start with...
PLA is the answer.
PLA remains the most popular filament for Bambu Lab printers because it's incredibly easy to print while producing beautiful surface finishes.
Perfect for
🎨 Decorative models
🦖 Toys
🏠 Home organisation
🪴 Planters
🎭 Cosplay
🛠 General printing
Why choose PLA?
✅ Easy first layers
✅ Fast printing
✅ Low warping
✅ Excellent detail
✅ Huge colour selection
💪 PLA+ – Stronger Without the Headaches
Need something tougher?
PLA+ offers increased impact resistance while maintaining the simple printing characteristics that make PLA so popular.
Perfect for:
🔧 Brackets
🧰 Workshop accessories
🪛 Tool holders
🏡 Everyday functional parts
🚗 PETG – When Strength Matters
PETG is one of the best choices for functional parts.
It offers:
✅ Better impact resistance
✅ Improved heat resistance
✅ Better moisture resistance
Excellent for:
🚲 Bicycle accessories
🚗 Automotive clips
🌿 Outdoor projects
🛠 Workshop tools
🏠 Functional household items
PETG can produce a little more stringing than PLA, but proper drying and tuning usually resolve this.
✨ Matte PLA – Beautiful Professional Prints
Matte PLA has become one of the fastest-growing filament categories.
Why?
Because it hides layer lines beautifully.
Perfect for:
🏛 Architectural models
🎭 Cosplay
🎁 Gifts
🖼 Display pieces
🪴 Decorative prints
🌈 Silk PLA – Stunning Glossy Prints
Want prints that really stand out?
Silk PLA creates an eye-catching glossy finish with vibrant colours.
Ideal for:
🐉 Dragons
🏆 Trophies
🎁 Gifts
🏺 Decorative models
✨ Display prints
🎨 Gradient PLA – Incredible Colour Transitions
Gradient filaments automatically transition between colours throughout your print.
Perfect for:
🐉 Dragons
🦖 Dinosaurs
🎨 Artwork
🎁 Display pieces
🌈 Multi-colour models
The larger the print, the more dramatic the colour changes become.
🔩 Carbon Fiber PLA – Engineering Performance
Need stronger, stiffer prints?
Carbon Fiber PLA combines standard PLA with chopped carbon fibres to produce lightweight, rigid parts.
Excellent for:
🚁 Drones
🚗 RC cars
🛠 Functional brackets
⚙ Engineering projects
⚠ Important
Carbon Fibre filament is abrasive.
A hardened steel nozzle is recommended because standard brass nozzles wear much faster when printing abrasive materials.
🧸 TPU – Flexible Filament
TPU is ideal for:
📱 Phone cases
🚪 Door stops
🛞 Tyre models
🧤 Protective covers
🛡 Vibration dampers
Can TPU be used in the AMS?
Generally no.
Because TPU is flexible, it can buckle during feeding. Most manufacturers recommend feeding TPU directly into the printer rather than through the AMS.
☀️ ASA – Built for Australian Conditions
Need something that can survive outdoors?
ASA is one of the best materials available.
Perfect for:
☀ Outdoor signage
🚗 Automotive parts
🌿 Garden accessories
🏠 Exterior brackets
Benefits include:
✅ UV resistance
✅ Heat resistance
✅ Weather resistance
⚠ Print ASA in a well-ventilated area or enclosed printer with appropriate ventilation due to fumes released during printing.
📦 Which Filaments Work with the AMS?
One of Bambu Lab's standout features is the Automatic Material System (AMS).
✅ Works Very Well
- PLA
- PLA+
- PETG
- Matte PLA
- Silk PLA
- Gradient PLA
⚠ Use With Care
- Carbon Fibre PLA (ensure your printer has a hardened nozzle and follow the filament manufacturer's guidance)
- Glow-in-the-dark filaments (abrasive)
❌ Generally Not Recommended
- TPU
- Other highly flexible filaments
Always check the filament manufacturer's recommendations before loading specialty materials into the AMS.
🛠 Tips for Better Bambu Lab Prints
💧 Keep Your Filament Dry
Moisture causes:
❌ Stringing
❌ Popping
❌ Poor layer adhesion
❌ Rough surfaces

🧹 Keep Your Build Plate Clean
A clean build plate dramatically improves first-layer adhesion.
Wash removable plates with warm water and a small amount of dishwashing liquid, rinse thoroughly, and avoid touching the print surface with your fingers. Follow Bambu Lab's maintenance recommendations for your specific plate type.
⚙ Match the Nozzle to the Material
Brass / stainless steel nozzle:
✅ PLA
✅ PETG
✅ Silk PLA
✅ Matte PLA
Hardened nozzle recommended:

Store filament in:
✅ Airtight containers
✅ Vacuum bags
✅ Fresh silica gel
Proper storage helps reduce moisture-related printing issues.
