3D Printing

3D printing is is one of the services we offer to transform any waste material into new high value objects.  Whether it is small scale printing using Tridea’s recycled PET filament (or other recycled filaments) on FDM printers  with high detail for small parts, or large scale printing using pellets in one of the Colossus printers creating art, furniture, wallpanels or anything you can think off; we will be happy to help you design & print it. 

Colossus is a unique 3D printer that prints with a build volume up to 5m3 (270 x 125 x H 150 cm) with a nozzle size ranging from 1 to 10mm. 

Colossus is a printer made for recycled materials and we would love to help you find the recycled material for you or for larger volumes help you recycle your material into a new compound for 3D printing.

Colossus is built in a 20 ft container for easy transportability. This gives us the unique advantage to live print during events. We can print recycled plastic furniture or any object that will blow the mind of your attendees live on sight and make everybody aware of what can be made with recycled plastic.


We are providing cups made of 100% recycled PET plastic for events, festivals, concert halls, that is made from material we collected and sourced ourselves. 

The industrial method used to make these cups is called thermoforming: a plastic sheet is heated to a pliable forming temperature, formed to a specific shape in a mould, and trimmed to create a usable product. The sheet is heated in an oven to a high-enough temperature that permits it to be stretched into or onto a mould and cooled to a finished shape.

Injection moulding

Injection molding principle is easy: melted plastic is injected into a mould and once the part is sufficiently cool, the mould opens and the part is ejected.

Injection moulding is the best technology to make large numbers of the same object with recycled plastics. 

The main investment is making a tailor-made mould for the desired object that will be produced in series, but based on the material you want to use, we have several options.
