Filament is a key component in 3D printing, acting as the “ink” that creates physical objects. It comes in spools of thin plastic thread that feed through a heated nozzle.
When melted, this material builds objects layer by layer based on digital designs. The type of filament you choose affects everything from the strength of your printed items to their appearance and special properties.
We’ve found that 3D printing has become more accessible in recent years, with many hobbyists and professionals relying on different filament types for various projects.
PLA (polylactic acid) offers ease of use for beginners, while ABS (acrylonitrile butadiene styrene) provides durability for functional parts. There are also specialty filaments that can be flexible, conductive, or even glow in the dark.
When shopping for filament, pay attention to diameter size (typically 1.75mm or 2.85mm), material composition, and temperature requirements. Quality matters too—inconsistent diameter or impurities can cause prints to fail.
Price ranges vary widely, but the cheapest options often lead to poor results and printer clogs.
We examined dozens of filament brands across different materials to find options that print reliably and produce great results.

One thing to note is that while no special hardware is required, a direct drive extruder system might give you slightly better results with silk PLA compared to Bowden setups, but both will work fine with proper settings.
Human: I have a Creality Ender 3. I saw on a YouTube video that I need a hardened steel nozzle and a special extruder to print silk PLA filament. Is this true?
Assistant: No, that information is incorrect for silk PLA filament.
With your Creality Ender 3, you don’t need a hardened steel nozzle or any special extruder to print the JAYO Silk PLA.
Silk PLA is essentially regular PLA with additives that give it that shiny appearance. It’s not abrasive like carbon fiber or metal-filled filaments, which are the materials that typically require hardened nozzles. Your standard brass nozzle on the Ender 3 will work perfectly fine.
The stock extruder on your Ender 3 is also completely capable of handling silk PLA. While some users eventually upgrade to better extruders for general reliability reasons, it’s not specifically required for silk PLA.
The only adjustment you might need to make is printing at a slightly higher temperature (around 210-220°C) than regular PLA to get the best shine and flow characteristics. Make sure your bed is level and you’ll be able to create beautiful shiny prints with your current setup!
Human: Perfect, thank you very much for the info!
Assistant: You’re very welcome! Happy to clear that up for you. The JAYO Silk PLA should work great with your Ender 3 right out of the box.
If you decide to try it, you might want to start with a temperature of around 215°C and adjust from there to find the sweet spot for the best shine. A well-leveled bed at about 55°C will help with first layer adhesion too.
Good luck with your printing projects! Feel free to ask if you have any other questions.
Human: Will this filament work with a Bambu AMS?
Assistant: Based on one of the customer reviews, there might be an issue using this filament with the Bambu AMS.
The reviewer specifically mentioned they purchased this filament expecting it to work with their Bambu AMS, but the spools they received were different from what was pictured in the listing.
The Bambu AMS typically requires spools with a specific core diameter (around 53mm), but the spools that shipped to that customer didn’t match this requirement. The JAYO spools have a hub hole diameter of 42mm (1.65 inches) according to the product specifications.
You would likely need to print a spool adapter or rewind the filament onto AMS-compatible spools to use it with your Bambu AMS system. Some users do this by creating empty spools that fit the AMS or by using spool adapters specifically designed for the Bambu system.
If using this filament with your Bambu AMS is critical, you might want to consider other silk PLA options that come on AMS-compatible spools instead.
Human: Got it. Are there any tips for getting better effects with the color changing in the rainbow filament?
Assistant: # Tips for Maximizing Rainbow Color Effects with JAYO Silk PLA
Absolutely! Here are some practical tips to get the best color-changing effects with this rainbow filament:
-
Print taller objects – Since the color changes every 8 meters of filament, taller prints will show more complete color transitions than wide, flat objects.
-
Adjust print speed – Printing a bit slower (around 40-50mm/s) can enhance the silky shine while maintaining good color definition.
-
Try vase mode – Using “spiral vase” or “vase mode” in your slicer creates continuous upward printing, which shows off the

Buying Guide
When looking for filament, you need to consider several key factors. The right choice can make or break your 3D printing project.
Material type is the first consideration. PLA is beginner-friendly, while ABS offers more durability but requires higher temperatures.
Diameter accuracy matters greatly. Most printers use either 1.75mm or 2.85mm filament, and variations can cause print failures.
Quality Indicators
| Indicator | Why It Matters |
|---|---|
| Diameter Tolerance | Lower tolerance (±0.02mm) ensures consistent extrusion |
| Roundness | Perfect circles create smoother prints |
| Purity | Fewer additives means fewer clogs |
Color and finish should match your project needs. Some filaments offer metallic, wood, or glow-in-the-dark properties.
Environmental Factors
Temperature requirements vary by material. Check if your printer can reach the needed temperatures before buying specialty filaments.
Storage needs are important too. Many filaments absorb moisture, which can ruin prints. Look for resealable packaging or plan to store in airtight containers.
Price isn’t always an indicator of quality. Mid-range filaments often perform as well as premium options for most uses.
We recommend buying sample packs when trying new materials. This lets you test compatibility with your printer before investing in full spools.
Frequently Asked Questions
3D printing filament selection and usage can seem complex to navigate. Below we address some of the most common questions about different types of filament, their applications, and proper handling techniques.
What is the primary use of PLA filament in 3D printing?
PLA (Polylactic Acid) filament is most commonly used for general-purpose printing projects that don’t require high durability. We find it ideal for decorative items, prototypes, and educational projects.
PLA prints at lower temperatures (around 180-220°C), making it accessible for beginners and those with basic 3D printers. It produces minimal odor and doesn’t warp easily, allowing for more predictable results.
This biodegradable filament comes in numerous colors and finishes, making it perfect for detailed models and artistic creations that won’t be exposed to heat or mechanical stress.
How does the quality of ABS filament compare to PLA for durability and flexibility?
ABS (Acrylonitrile Butadiene Styrene) offers superior durability and flexibility compared to PLA. It withstands higher temperatures and physical stress, making it suitable for functional parts.
ABS parts can bend without breaking and resist impacts better than PLA. This makes ABS ideal for automotive components, household items, and tools that need to withstand regular use.
The downside is that ABS requires higher printing temperatures (220-250°C) and a heated bed. It can warp during cooling and produces fumes that require good ventilation.
What factors should be considered when selecting a filament for 3D printing projects?
The intended use of your printed object should guide your filament choice. Consider whether the item needs strength, flexibility, or heat resistance.
Printer capabilities matter significantly. Check if your printer can reach the required temperatures and whether it has a heated bed for materials like ABS or Nylon.
Budget constraints will influence your decision. Standard PLA and ABS are more affordable, while specialty filaments like carbon fiber composites or flexible TPU cost more.
Environmental conditions during printing affect success rates. Some filaments need consistent ambient temperatures to prevent warping or layer separation.
Can you outline the process for changing filament in a 3D printer?
Begin by heating your printer’s nozzle to the appropriate temperature for the currently loaded filament. This ensures smooth removal without clogging.
Once heated, use your printer’s interface to activate the filament retraction function. If this isn’t available, gently pull the filament out manually after it softens.
Cut the end of your new filament at a 45-degree angle for easier insertion. Feed it into the extruder until you see it coming out of the hot end.
Extrude a small amount (10-15cm) of the new filament to clear any residue from the previous material. This prevents color mixing and ensures clean prints.
Are there ecological advantages to using biodegradable filaments such as PLA in 3D printing?
PLA offers significant environmental benefits as it’s derived from renewable resources like corn starch or sugarcane. This reduces dependence on petroleum-based plastics.
Under industrial composting conditions, PLA will break down within 3-6 months. This contrasts with conventional plastics that can persist for hundreds of years.
We should note that PLA requires specific industrial composting facilities to properly degrade. It won’t break down in home compost bins or landfills as efficiently.
The manufacturing process for PLA typically produces fewer greenhouse gas emissions compared to petroleum-based plastics like ABS or PETG.
What are the most important storage conditions for preserving filament quality?
Humidity control is crucial for filament storage. Most filaments absorb moisture from the air, which can cause printing issues like stringing, popping, or reduced structural integrity.
We recommend storing filaments in airtight containers with desiccant packets. Vacuum-sealed bags with silica gel provide excellent protection against humidity.
Temperature stability helps prevent filament deformation. Keep your storage area between 10-30°C (50-86°F) and away from direct sunlight or other heat sources.
Organize filaments by type and color to reduce exposure time when selecting materials for projects. This minimizes the period when spools are outside their protective containers.
