Types of Filament Available
After working with dozens of filament brands in the DunaTech workshop, I can tell you that not all filaments are created equal. Here in Barcelona, local stores and distributors usually offer a good variety, but it’s important to know what to look for. Here are the main types:
PLA
– **Advantages**: Easy to print, often doesn’t require a heated bed, good surface quality.
– **Disadvantages**: Lower heat and impact resistance.
– **Ideal for**: Decorative projects, quick prototypes, and non-functional parts.
ABS
– **Advantages**: High impact resistance, withstands higher temperatures.
– **Disadvantages**: Emits odors while printing and requires a closed chamber printer to avoid warping.
– **Ideal for**: Functional and durable parts.
PETG
– **Advantages**: Impact-resistant, flexible, good layer adhesion.
– **Disadvantages**: Can be tricky to print due to stringing.
– **Ideal for**: Parts that need mechanical and chemical resistance.
TPU
– **Advantages**: Flexible material, ideal for applications like seals, soles, or impact-absorbing parts.
– **Disadvantages**: Requires slower printing settings.
– **Ideal for**: Flexible and durable parts.
Where to Buy in Barcelona
After visiting several local stores in Barcelona and comparing prices with AliExpress, here are the best options:
Physical Stores
1. **BCN3D Store**: Specializes in high-quality PLA and PETG filaments. While their prices aren’t the lowest, they offer very helpful technical advice for beginners.
2. **Materialize Barcelona**: Located in the city center, it’s a good option for buying ABS and TPU. They also often have local deals.
3. **FabLab Barcelona**: If you’re looking for something more experimental, this space also offers specialty filaments like Nylon and wood composites.
Buying Online: AliExpress
In my tests with filaments purchased on AliExpress, I was impressed by the quality of brands like eSUN and Sunlu. They are reliable and offer competitive prices. Plus, they often have bulk discounts.
Common Problems and Solutions
Problem: Filament not adhering to the bed
– **Cause**: The bed temperature may be too low, or the surface isn’t clean.
– **Solution**: Clean the bed with isopropyl alcohol and adjust the temperature according to the filament type (60°C for PLA, 100°C for ABS).
Problem: Brittle filament
– **Cause**: The filament has absorbed moisture.
– **Solution**: Use a filament dryer. You can check out our guide on the Sovol Filament Dryer, which we tested at DunaTech.
Problem: Extruder jams
– **Cause**: Dirt in the extruder or incorrect temperature.
– **Solution**: Clean the extruder with a fine needle and adjust the temperature according to the manufacturer’s recommendations.
