How to Make 3D Printer Filament?

how to make 3d printer filament

Let us understand how to make 3d printer filament. 3D printer filament is a type of printing material that is utilized by FFF-type 3D printers. It is presently one of the most popular 3D printing material types in the world. Unlike powder and liquid resin for other 3D printing technologies, the filament is made into a single continuous narrow plastic thread hundreds of meters long, which is commonly spooled into a reel for storage and printer feeding. After learning so much, one would be curious about how to make 3D printer filament. And this is the topic of this essay.

What Plastics Can You 3D Print With?

Here are the three most frequently utilized polymers that have contributed to 3D printing’s tremendous progress:

Polylactic Acid (PLA)—It’s no surprise that one of the world’s most extensively used bioplastics is also the most popular in 3D printing. PLA is a biodegradable aliphatic polyester made from organic resources like maize starch or sugarcane.

ABS (Acrylonitrile butadiene styrene) is another common 3D printing material. Polymerizing styrene and acrylonitrile with polybutadiene produces this terpolymer. Beginners like the filament’s ease of use, as well as its durability, strength, heat resistance, cost-effectiveness, and flexibility.

PVA (Polyvinyl Alcohol Plastic) is a water-soluble plastic typically used as a glue, thickening, or packing film. PVA is used in 3D printing to provide a support framework for parts of a product that may warp or collapse during the printing process, rather than to manufacture the end product.

How to make 3D printer filament from plastic bottles?

Making usable goods out of local waste plastic using 3D printing is a rather simple procedure. The process is known as distributed recycling and additive manufacturing, or DRAM for short.

Shredding is the first step.

PET bottles are recycled filament, which we clean completely and shred into small plastic flakes.


These flakes are cleaned, heated, and then extruded into a clean 1.75 or 2.85 mm string.


This newly recycled filament is coiled on a spool and placed in cartons.


A batch of 100% recycled filament has been prepared for printing. This method, which can be done at home or in the factory, allows you to make a huge variety of completely functioning things out of plastic bottles.

How to make PLA filament?

Polylactic Acid, PLA material, or PLA filament is made from renewable green sources like starch, maize, or sugar cane. Because it is recyclable, it is better for the environment than other materials. The ideal material for prototyping and 3D modeling. PLA filament is a common 3D printing material, especially when employing the FFF method.

During the initial stage of shaping, the pellets are heated in a filament extruder with a heating chamber. In this chamber, pellets are melted down into a sticky material that can be readily molded. As a result, the pellets start to stick together and form a stranded substance.

PLA offers the following advantages

Low printing temperature: PLA does have a lower printing temperature than other thermoplastics (for example, the optimal printing temperature for PLA is approximately 180°C, whereas ABS is around 250°C). Because of this, PLA is less prone to distorting and clogging the nozzle during the printing process.

Ease of use: PLA is one of the most user-friendly 3D printing materials.

Color and mixing options: PLA is coloured easily and is available in a wide selection of colors and mixes.

Simple post-processing: PLA prints can be sanded, polished, and painted with ease, resulting in a better surface finish with minimal work.


1. How do you produce filament for 3D printing?

Gather all the plastic garbage.
● Cleaning the garbage is as simple as dividing it into categories.
● After the trash has been processed, plastic can be used as a shredder or grinder.
● Shred the pieces to size and feed them directly to a 3D printer with a material hopper that can manufacture 3D objects.
● Print a product.

2. How to make PLA filament at home?

To produce your filament, just melt bulk plastic pellets, mold the molten plastic into a long continuous strand, then wound that strand around a spool as soon as it cools. That may sound simple, but excellent filament must be fully constant in composition and diameter to print effectively
