3D printing With Recycled Filament


The final step in our recycling journey is here…it’s time to 3D print with the filament we extruded from our plastic recycled waste. 

We must say it has been a very exciting journey! We’ve learned which plastic materials are and aren’t recyclable, how to shred our plastic waste, how to extrude our plastic waste into filament and now finally how we can 3D print with the filament we made. 

If you missed any of the previous blog posts, we recommend you checking them out first before continuing on with this one, as each blog post is an important step to get to this final step of 3D printing. 

If you are not aware of what an (FDM) 3D printing machine is or if you would like to learn more about it, you can check our blog post out where we guide you through FDM 3D printing. 



How To Get Started 

Testing Phase

Now that you have your filament, we recommend that you first use a spool with a small amount of the filament on. Since you extruded filament from recycled plastics, it’s possible that the plastic material will not react the same way as you are used to. Therefore, it’s better to start with a small print before diving into the actual print you want to create. 

Filament Texture

Before you start 3D printing, it is important to first check your filament texture out. Your filament needs to have an even consistency and it needs to have a round texture. If your filament does not have the same texture all over, we recommend you to go one step back and to reproduce your filament. Perhaps our previous video can help, where our material expert, Timo, explains  how you can extrude filament perfectly. 

Experiment Phase

Keep in mind that 3D printing is an experimental process just like extruding filament. Like we mentioned previously, “don’t be too harsh on yourself when you don’t extrude the perfect filament right away!”. In this case, don’t be too harsh on yourself when you don’t print the perfect 3D print right away! Just be patient and have some fun with it.

Temperature & Printing Settings

Make sure that you have the right temperature and printing settings. Each plastic material reacts differently to heat, if you for example; have a too high-temperature setting, your filament will tend to melt too quickly which will cause your 3D print to not look evenly everywhere. We recommend you to first find the right settings on the internet, our material experts do so too when printing with new material. If you are new to 3D printing, no worries, PinShape has created a guide for beginners in which they give you all the right base settings. 

Now that you know all the things you should do to get started, you can start 3D printing! If you make a print and you share it on social media, make sure to tag us as we love to see your creations. 

Thank you for being part of this journey, we hope that you learned as much as we did. If you have any questions, don’t hesitate to contact us, we love hearing back from you! 

We hope to see you back on another journey.
