What people say about Greenboy3D

Save up to 90% on your 3D printing costs

Every filament and piece of plastic you’ve seen started as plastic pellets. While a spool of filament (1kg) costs $20 – $60, the same amount in pellets is just $3 – $8.

You can save up to 90% on printing costs by upgrading your 3D printer with my universal Pellet-Extruder-Printhead, allowing you to print directly with pellets.

More about Pellets

Recycle failed prints and plastic into anything

With a Greenboy Pellet-Extruder-Printhead, you can recycle any plastic waste—like empty filament spools, water bottles, yogurt cups, and failed prints—into new objects.

Simply shred the plastic into pieces smaller than 0.2 inches (5 mm) and 3D print with them again. This method offers a sustainable future, turning plastic waste into new, purposeful items instead of discarding it.

More about Recyling

3D print with chocolate, sugar or anything else melting in the range: Ambient – 330 C°

It’s true! You can 3D print chocolate with my Pellet-Extruder-Printhead. Though not originally intended, any meltable material smaller than 0.2 inches (5 mm) works fine.

For food safety, most parts in contact with food are stainless steel. If strict food safety is a priority, you can spray the rest of the extruder with food-grade silicone spray or use other methods…

Advantages of my Greenboy Pellet Extruder

Extremely Universal

Thanks to the concept of using 3D printable adapters, you can use this extruder on almost any 3D Printer

Lightweight ~ 700 grams 

Through innovative thinking I managed to replace a lot of metals parts with 3D printable plastic parts and this significantly reduced the weight

Most inexpensive Pellet Extruder

Through innovative thinking and some new approaches I managed to reduce the production costs, which allows to have a lower price 

Easy to use

Thanks to some special features, it is quite easy to use this pellet extruder, because many problems conventional 3D Pellet Extruders have like unloading pellets have been solved

125 – 200g/h Flowrate

Depending on the material you use, its size, shape and viscosity, you can expect to achieve a maximum flowrate between 125 – 200 grams per hour with a 1mm nozzle. Using a bigger or smaller nozzle does influence the maximum flowrate capabilities…

Control color and transparency level of your prints

Instead of buying pre-colored filament and being limited to that color and spool, you can buy a bag of plastic pellets and some color pigments, sprays or paint.

Now you can universally print with any color you desire at a fraction of the filament cost simply by mixing a specific amount of pellets with a chosen color, which will result in, for example, 1/2 pounds of blue-colored PLA for one of your specific projects.

Depending on the concentration of colors in your pellets, you can achieve everything in the range of transparent prints with a little color and up to full-solid color prints. Another cool thing is mixing or stacking different batches of colored pellets on top of each other. This will give amazing gradient colors to your 3D prints, as you can see in the image near by.


Step 1

Apply a Color on Pellets


Step 2

Mix everything by shaking


Step 3

Let everything dry out

+ you can add custom additives to your pellets

“Additives” is a word for substances that improve or change the properties of plastics. By using the same methods for coloring your pellets, you can add, for example, “glow in the dark” substances to your pellets to get cool-looking prints that glow at night. But that is just one out of many possibilities you can try out…

The Person behind Greenboy3D

Hi, my name is Kristian, I’m 23 years old and my mission is to make Pellet 3D Printing globally less expensive and more accessible…

 

Back in the year 2022 I was very frustrated with the cost of 3D Printing and especially the waste it produces. At that time, I knew that 3D printing directly with Plastic Pellets & Shredded waste is possible.

But there were no low cost options, and it also seemed like as if the 3D printing industry doesn’t have much interest in developing this technology, despite its great potential.

This frustrated me even more, so I decided to develop my own Pellet Extruder without having any knowledge about engineering at that time…

For more than 2 years I struggled, worked extremely hard and spent most of my income on the development while living under poor conditions…

No matter how hard times were, I never gave up and this why Greenboy3D exists today…
