When it comes to 3D printing, PLA filament is often the go-to material for hobbyists, makers, and terrain builders alike. But did you know there’s a wide variety of PLA types available? Each with unique characteristics that can dramatically change the look, feel, and function of your prints?
In this post, we’ll explore six different types of PLA filament that can help you get more creative and achieve better results in your 3D printing projects.
1. Standard PLA Filament
Standard PLA is the most commonly used filament for 3D printing. It’s easy to print with, widely available, and typically comes in 1.75mm diameter. It’s a solid choice for general-purpose projects, especially things like tabletop terrain, miniatures, and functional prototypes.
2. Matte PLA Filament
Matte PLA contains an additive that helps to reduce the visibility of layer lines, giving your prints a smoother, more uniform surface. This makes it ideal for prints that need a cleaner, more professional finish—great for display models or presentation pieces.
3. Silk PLA Filament
Silk PLA creates a glossy, reflective surface that almost looks metallic or wet. While it’s slightly more brittle than standard PLA, the visual impact is excellent for decorative prints, cosplay elements, or display miniatures where strength isn’t a primary concern.
4. Gradient / Rainbow PLA Filament
Gradient or rainbow PLA filaments are colour-shifting, meaning the colour changes gradually as the filament is extruded. This adds natural variation to your prints without the need for painting—perfect for larger objects or when you want a multicolour finish straight off the printer.
5. Translucent PLA Filament
Translucent PLA allows light to pass through, giving a semi-transparent appearance. It comes in a variety of colours and is a great option for lighting effects, backlit elements, or prints that need a glowing or ethereal look.
6. Fluorescent & Glow-in-the-Dark PLA Filament
These speciality filaments react to light in different ways—fluorescent PLA responds to UV exposure with a vivid pop of colour, while glow-in-the-dark PLA stores light and emits it in darkness. They’re a great choice for sci-fi scenery, signage, or anything designed to stand out in low light.
Where to Get These Filaments
We sourced these filament types from Siddament, a fellow Aussie supplier with a growing range of PLA and other filament types. Whether you’re after bold colours, smoother finishes, or specialty effects, they’ve got plenty of options to explore.
Final Thoughts
Choosing the right filament can be just as important as your model or printer settings. By experimenting with different types of PLA, you can unlock new creative possibilities and enhance the final look of your 3D printed projects.
