- Check filament diameter: Ensure that your slicer settings match the actual diameter of your filament, as variations can lead to incorrect extrusion rates.
- Adjust extrusion multiplier: Experiment with adjusting the extrusion multiplier in your slicer settings to fine-tune the amount of filament being extruded.
- Calibrate extruder steps: Calibrating your extruder’s steps per millimeter can help ensure accurate extrusion rates, reducing under-extrusion or over-extrusion issues.
Warping and Bed Adhesion Issues
Warping occurs when printed objects start to lift or curl at the corners, often caused by uneven cooling or poor bed adhesion. This can lead to poor layer adhesion, distorted prints, or even complete print failure.
- Level the printing bed: A level printing bed is crucial for proper first-layer adhesion. Calibrate your bed leveling before each print to ensure a consistent, flat surface.
- Adjust nozzle height: Ensure that the nozzle height is set correctly for optimal first-layer adhesion. A nozzle that is too high or too low can cause adhesion problems.
- Use a heated bed or adhesion aids: A heated bed can help prevent warping by maintaining consistent temperatures throughout the print. Alternatively, adhesion aids like painter’s tape, glue stick, or specialized build surfaces can improve bed adhesion.
Stringing and Oozing
Stringing and oozing occur when filament leaks from the nozzle during non-printing movements, leaving behind thin strands or blobs of material on the printed object.
- Adjust retraction settings: Retraction pulls the filament back into the extruder during non-printing movements, reducing oozing. Experiment with retraction distance and speed in your slicer settings to minimize stringing.
- Optimize print temperature: Printing at too high a temperature can cause filament to ooze more readily. Test different temperatures to find the optimal range for your specific filament.

How to Go Green with 3D Printing: A Guide to Eco-Friendly Filaments and Practices
3D printing is an amazing technology that can create anything from toys to tools. But it also comes with a cost: plastic waste. According to a study by the University of California, Irvine, 3D printing produces up to 10 times more waste than conventional manufacturing methods1. That’s why it’s important to adopt sustainable and eco-friendly practices when using 3D printers. In this guide, we’ll show you how to choose biodegradable filaments, recycle your 3D printing waste, and promote green 3D printing in your community.
What are Biodegradable Filaments and Why Should You Use Them?
Biodegradable filaments are 3D printer materials that can decompose naturally over time, reducing the amount of plastic that ends up in landfills or the environment. They are usually made from plant-based or bio-based resources, such as cornstarch, sugarcane, or potato. They are also renewable and carbon-neutral, meaning they don’t contribute to greenhouse gas emissions.
Some of the most popular biodegradable filaments are:
- PLA: PLA stands for polylactic acid and is derived from cornstarch or sugarcane. It is the most common biodegradable filament and one of the easiest to print with. It has good strength, stiffness, and biocompatibility, making it suitable for a wide range of applications, such as containers, non-functional prototypes, toys, models, figures, medical and dental tools, and kitchenware.
- BioPET: BioPET is a bio-based version of PETG, which stands for polyethylene terephthalate glycol. It is made from sugarcane or other renewable resources. It has similar properties to PETG, such as strength, durability, flexibility, and clarity, but with a lower environmental impact. It is ideal for printing functional parts that require high performance and resistance to heat and chemicals.
- PCL: PCL stands for polycaprolactone and is derived from petroleum or natural gas. It is a low-temperature filament that can be printed at around 80°C. It has high toughness and elasticity and can be reshaped after printing by heating it up. It is often used for printing flexible or wearable items, such as bracelets, belts, or shoes.
- PHA: PHA stands for polyhydroxyalkanoate and is derived from bacterial fermentation of organic waste. It is a biopolymer that is more resistant to water and UV than PLA. It has good strength and flexibility and can be blended with other materials to enhance its properties. It is suitable for printing outdoor or aquatic items, such as plant pots, bird feeders, or fishing lures.
- Starch-based filaments: Starch-based filaments are made from starch extracted from plants like potato or rice. They are biodegradable and compostable and have similar characteristics to PLA. They are often mixed with other additives or colorants to improve their printability and appearance. They are great for printing decorative or educational items that don’t require high durability or performance.
By using biodegradable filaments, you can reduce the environmental impact of your 3D printing projects and create more eco-friendly products.
How to Recycle Your 3D Printing Waste and Save Money
Recycling your 3D printing waste is another way to minimize your environmental footprint and save money on buying new materials. There are several ways to recycle your 3D printing waste:
