Can You Recycle Plastic For 3d Printing? 3D Printer Recycling Plastics

The 3D printing community is always looking for new ways to create innovative and sustainable designs. As more plastic objects are created, it’s important that we find a way to recycle them. This blog post explores how 3D printer users can recycle their plastic waste into usable filament for future projects!

The first step in the recycling process is sorting your plastics by color and type: PET (toys), PVC (clothes), LDPE (shampoo bottles) Polypropylene (plastic bags).

This makes it easier to identify which types of plastics you have so they can be turned back into filament pellets.

Can you recycle plastic for 3d printing? (recyclable plastics)

No, the two classic types of 3D printer filaments, ABS and PLA are not recyclable by most curbside municipal recycling programs. This is because they can’t be broken down into their individual elements to create a new product like other plastics such as HDPE or polystyrene these days – which means you have no choice but to throw them away when there are failed prints on your hands!

Fortunately, though with the introduction of newer bio-based materials from sustainable sources such as PEI (polyethylene/natural), we may see some changes happening soon enough in how people Think About Recycling Their Waste Products.

However, if you are using ABS or PLA plastics in the 3D printer filament that are not recyclable, it’s crucial that you look into what is available for recycling programs in your area to help reduce the amount of plastic waste going to landfills. Because neither of these filaments biodegrades naturally over time, they will simply be sitting in the landfill and taking up space for hundreds of years if not properly recycled or repurposed.

As a result, with so many concerns over landfills and waste management becoming more apparent every day with the introduction of new Bio-Based 3D printer filaments such as PEI (polyethylene/natural) that are a “green” alternative to ABS and PLA, it’s a good idea to be aware of what your options are in the end for recycling your 3D printing waste.

In many metropolitan areas these days they have been able to become more forward-looking with their initiatives in making recycling available via curbside pickup programs where you can simply put the products in the recycling bin when it’s full.

This way you can simply buy a plain paper bag for your 3D printer filament, use up all of the material in the spool and then recycle it at home with everything else.

Of course, this is only recommended if you are using an ABS or PLA that isn’t recyclable by your local recycling program.

In the end, there are a plethora of ways to recycle your 3D printing plastics and filaments properly either at home or through a company near you but it simply comes down to being proactive in seeing what’s available and going from there.

How to make 3D printer filament from plastic bottles? (recycle plastic bottles)

Water bottles were collected, cleaned (properly) and any external caps or seals were also removed.

The bottled was then vacuum sealed and heated to reduce its size once cooled they are cut into smaller chunks with a saw; after that these pieces will be shredded using our SHR3D IT machine which can create nylon-like material out of it!

Filament recycling machine? (printing plastic machine/printing recycle plastic)

We all know that any 3D printer takes some time to warm up before it can actually start printing.

Sometimes this process might take hours, even days (if it’s used for PLA). During this enforced downtime the only thing the user can do is to wait until the machine is ready.

While waiting many users think about what they could do to make their 3D printer more useful.

The answer is – use it as a filament recycler!

PVC tube of 50mm diameter, a 25mm PVC tube, and a small piece of the wooden board are the only materials that you will need to build this wonderful filament recycler.

The only thing you should be careful about when building this project is to make sure that the long tube is firmly connected with both other parts. The core of the filament recycling machine is a washing machine motor which was used in this project for two reasons: its low price and high torque. It has a 50Hz frequency, 1/6HP, and 2500RPM.

This motor is connected to a dynamo which in turn provides electrical power to the system. The advantage of this dynamo over an ordinary DC motor is that it has built-in magnets for generating electricity when turned thanks to its rotating magnetic field.

The filament recycling machine starts with ‘loading’ the spool of the used filament.

It is done by inserting one end of the filament into a special hole that will catch it and hold it until someone starts to ‘unload’ the system using another button. If no action is done after 10 seconds, the machine will go back to ‘loading’. This easy mechanism allows us to use this machine as an automatic filament loader.

The filament recycling machine has two buttons for ‘loading’ and ‘unloading’ the filament. One push on the ‘unload’ button will release your filament into a bin where you can later reuse it in one of many ways (with 3D printers, RepRap, DIY extruders, or even hand-made objects).

One push on the ‘load’ button inserts one meter of filament into the 3D printer’s hot-end ready for printing.

Advantage (failed prints)

The main advantage that this filament recycling machine has over similar DIY projects is that it can be used as a filament loader. This makes it possible to use it with any current 3D printer which you already have and allows you to add an auto-loading system.

There are many possible applications for the filament recycling machine: 3D printer filament loader, automatic color changing in dual extrusion machines and even using it as a ‘bridge’ between two different spools of the same material (especially if they have different diameters).

A spool with a smaller internal diameter can be loaded from one side and a motor with some kind of gear can be used to wind the filament into the bigger spool from the other end.

Another possible use for this machine is as a filament cleaner.

It works by accelerating the filament as it goes through the PVC tube which makes it hit a board on its way out.

That impact breaks off any dust and plastic chips which might have been stuck to the filament. The holes drilled in a board help to make sure that even ABS with high shrinkage goes through safely without leaving any traces of itself on the other side.

And finally, you can use it as a color changer. All you need is at least two nozzles (for example 0.4mm and 0.8mm) on your hot-end, some kind of gear or sprocket wheel attached to the motor’s shaft, and an easy way to switch between them (like a sliding mechanism).

So instead of stopping a print because you need a different color filament, just load another color into the recycling machine and after a few seconds, it will be ready to go!

The filament recycling machine is a great piece of ‘DIY engineering’ that can make your life easier.

To build it you only need a 25mm PVC tube, a 50mm PVC tube, and a small piece of wooden board. The only challenge that awaits you is to put all the parts together in the right way.

Conclusion

It seems like you can do anything with a 3D printer these days. From fixing the family heirloom to making your own toys, there’s just no limit to what you can accomplish in the world of DIY projects and crafts. But how about recycling plastic for 3d printing?

Turns out that is possible too! If you’re interested in giving it a try yourself, check out this article on how to recycle plastics for 3d printing. You’ll be glad you did when all those leftover milk jugs start piling up around your house!
