PLA filaments for 3D printing
PLA is the most versatile and simplest material for 3D printing, ideal for beginners and experts alike. It is perfect for prototypes, decorations and detailed models. It prints reliably without warping, adheres well and delivers clean detail.
At Filamentor you will find the cheapest PLA filaments from the Smart print and Professional lab (Prof. lab) series. They guarantee stable properties and a consistent diameter across a wide range of colours. You get a quality material for home and professional use at an unbeatable price.
Buying guide
Polylactic acid, known as PLA, is the absolute foundation of FDM 3D printing. This biodegradable plastic made from corn starch stands out mainly for its extremely easy printing and minimal warping during cooling. Whether you are just starting with 3D printing or you are an experienced maker with a print farm, quality PLA filament is a must-have in your workshop. We stock over 230 items in a wide range of colors, and we actively test filaments from established brands like Smart Print and Prof. lab on our own printers.
What PLA filament is good for
Thanks to great layer adhesion and the ability to print fine details, PLA filament is ideal for visual models and prototypes that will not be exposed to high temperatures. It is most commonly used for:
- Detailed miniatures, figurines and indoor decorative items.
- Quick visual prototypes to verify shape and size before final production.
- Board games, architectural models and educational tools.
- Boxes and organizers that will not sit in the sun or a hot car.
Recommended print settings
| Parameter | Value |
|---|---|
| Nozzle temperature | 190 to 220 °C |
| Bed temperature | 0 to 60 °C (heated bed not required) |
| Enclosure | No (an open printer with strong part cooling is an advantage) |
| Practical tip | For sharp overhangs and bridges, set part cooling to 100%. |
When to choose PLA and when to pick another material
PLA filament offers great surface quality and prints very easily, but its main weakness is low heat resistance, as the material softens around 60 °C. If you need to print mechanically stressed parts or items for outdoor use, we recommend choosing PETG. This material is more heat and mechanically resistant, although complex overhangs are slightly harder to print. If you like easy printing but require higher impact resistance, the improved PLA+ is a great alternative.
Frequently asked questions
How do you properly store PLA filament?
Even though PLA is not as prone to absorbing moisture as nylon or PETG, we recommend keeping your spools dry. A sealable plastic box with silica gel is ideal to prevent the filament from becoming brittle and snapping. This ensures your 1 kg PLA filament retains optimal printing properties for a long time.
Why is my first layer failing?
The most common cause is a poorly calibrated nozzle distance from the bed or grease on the build plate. Before printing, we recommend thoroughly degreasing the surface with isopropyl alcohol and checking the nozzle height. The first layer should be slightly squished into the bed, but not extremely flattened or just loosely laid down.
Are cheap PLA filaments suitable for precise printing?
Yes, even affordable materials offer a consistent 1.75 mm diameter and reliable results. Cheap PLA filaments from Smart Print start at a very affordable price for a 1 kg spool and are fully sufficient for regular home projects. They print just as easily as premium variants, so you do not have to worry about degraded surface quality.
Whether you are looking for a basic material or special colors for your next project, you will definitely find it here. If you need to explore other plastics, check out all filaments in our range. For more technical prints, PETG filaments will serve you well, while for increased strength while maintaining easy printing, we recommend PLA+ filaments. If you print decorations and require high gloss, you will certainly be interested in Silk PLA. For makers on a tight budget, we have also prepared a cheap filaments category where you will find reliable material for everyday printing.
