Guide to Buying PLA Filament

The selection of PLA filament on the market can be overwhelming. Different types, colours, and technical specifications often make choosing the right material complicated. Whether you're printing detailed models, functional prototypes, or quick drafts, the choice of filament is crucial for the final result.

This guide is designed to help you understand the key features of PLA filaments and make an informed decision. As your Joybuy Product Recommendation Officer, I have compiled objective criteria and product data to provide you with clear guidance.

What to Look for When Buying PLA Filament

Before you buy PLA filament, you should consider several technical aspects that significantly influence the print quality and the properties of the finished object.

1. Filament Type: PLA, PLA+, or High-Speed?

The material is the foundation of every FDM 3D print. PLA (Polylactide) is particularly popular with beginners due to its ease of use and low tendency to warp. However, there are specialised variants:

• Standard PLA: Ideal for decorative objects, figurines, and quick drafts where high mechanical strength is not required.
• PLA+ Filament: A modified version of PLA that often features improved toughness and impact resistance. It is well-suited for functional parts that need to withstand a certain amount of stress.
• High-Speed PLA: Specially formulated for modern 3D printers that operate at high speeds. This FDM filament allows for significantly shorter printing times without compromising the quality or dimensional accuracy of the print.

2. Dimensional Accuracy and Diameter

The consistency of the filament diameter is critical for a smooth and error-free print. The most common standard is PLA filament 1.75mm. Pay attention to the tolerance specified by the manufacturer. A dimensional accuracy of +/- 0.02 mm is considered very precise and minimises the risk of nozzle clogging and uneven extrusion. A 1kg filament spool is the most common size for most projects.

3. Surface Finish: Matte or Glossy?

The filament's finish has a major impact on the aesthetics of the final print.

• Glossy PLA: The classic look, which often makes colours appear more vibrant.
• Matte PLA: A matte PLA filament creates a low-reflection, velvety surface. This effect can visually conceal layer lines and gives objects a high-quality, professional appearance. It is particularly sought after for design objects, architectural models, and visual prototypes.

Recommended PLA Filament Products

Here is a selection of filaments that stand out for their specific properties, tailored to different applications.

1. CaiLab 3D Printer Filaments PLA+ Bio - White

Why It Stands Out This PLA+ filament from CaiLab positions itself as an eco-conscious choice. According to the manufacturer, it is made from corn extract and is biodegradable. It combines the easy printability of standard PLA with the enhanced mechanical properties of PLA+.

Advantages

• Material Base: Made from biodegradable raw materials.
• Improved Properties: As a PLA+, it potentially offers higher toughness compared to conventional PLA.
• Reliability: Designed for broad compatibility with most FDM 3D printers and a high print success rate.

Who It's For Users looking for a reliable all-rounder for everyday printing projects who also value materials from renewable resources. It is suitable for prototypes, hobby projects, and functional parts with moderate stress requirements.

2. Creality Hyper PLA Peach Powder 1KG

Why It Stands Out Creality Hyper PLA is specifically designed for high-speed printing. According to the manufacturer, it enables printing speeds of up to 600 mm/s, which can drastically reduce production time for large or complex models. The high dimensional accuracy of +/- 0.02 mm supports consistent print quality even at a high pace.

Advantages

• High Print Speed: Formulated for speeds from 30 to 600 mm/s, ideal for rapid iterations and production.
• Precise Dimensional Accuracy: The +/- 0.02 mm tolerance ensures reliable extrusion and minimises print errors.
• Broad Compatibility: Compatible with most FDM 3D printers, not just those from Creality.

Who It's For Professional users, engineers, and makers who own a modern high-speed 3D printer and want to maximise their productivity. Ideal for rapid prototyping, manufacturing large objects, and anyone who doesn't want to wait long for their prints.

3. CAILAB 3D Printer Filament PLA Matte - Misty Lilac

Why It Stands Out This filament from CaiLab is distinguished by its unique surface finish. The matte PLA creates a soft, non-reflective texture that gives printed objects an artistic and high-end look. According to the manufacturer, the surface helps to hide layer lines and provides a smooth, tactile result.

Advantages

• High-Quality Matte Finish: Lends prints a professional, low-reflection aesthetic.
• Conceals Layer Lines: The matte texture can reduce the visibility of print layers.
• Artistic Colour Palette: Available in a range of colours designed for design and art projects.
• Good Printability: Engineered for trouble-free processing with good bed adhesion and a low tendency to clog.

Who It's For Designers, artists, architects, and hobbyists for whom the visual quality and feel of the final product are paramount. Perfect for exhibition pieces, decorative objects, and products that require a premium finish.

Frequently Asked Questions (FAQ)

What is the difference between PLA and PLA+ filament?

PLA+ is an evolution of standard PLA. It is modified by adding additives to improve certain mechanical properties. Typically, PLA+ filament is tougher and more impact-resistant than conventional PLA, while retaining its ease of printing. The exact properties can vary by manufacturer.

How should you store PLA filament correctly?

PLA is hygroscopic, meaning it absorbs moisture from the air. Moist filament leads to poor print quality (e.g., bubbling, brittle prints). Therefore, always store your 3D printer PLA filament in a cool, dry place. It's best to keep it in a resealable bag with the included desiccant (silica gel). For long-term storage, special filament dry boxes are suitable.

Can any 3D printer use high-speed PLA?

While High-Speed PLA is generally compatible with most FDM printers, it only reaches its full potential on printers designed for high speeds. These printers feature a stable frame construction, powerful motors, and advanced firmware (e.g., Klipper) to execute fast movements precisely and without quality loss. On a slower printer, it can be used like normal PLA, but without the speed advantage.
