Biomaterials

The Shelduck 3D Bio Pulp Printer uses a pulp of natural fibers and natural binders. The binders are starch-based. We currently use potato starch, but it is also possible to use cornstarch or other starch sources. You can create eco-conscious designs that seamlessly blend form and function with these great bio materials.

We have experience with a variety of (virgin) natural fibers and waste streams from the agri and food sectors.

Some of the natural fibers we have worked with include:

  • Sunflower husks
  • Bell pepper scraps (waste stream)
  • Cellulose (including old cardboard)
  • Recell cellulose (waste stream from water purification)
  • Cow manure
  • Wood sawdust / chips

We are also working on using other natural fibers, such as:

  • Hemp fiber
  • Chrysanthellum clippings (waste stream from chrysanthemum cultivation)
  • Cattail
  • Willow fibers
  • Flax

In addition, there are many other potential natural fiber sources, such as coconut, kenaf, bamboo, rise husk etc.

Benefits for you using bio materials in 3D printing

You can profit of these many benefits using bio materials in 3D printing.

  • Sustainable: They are made from renewable resources, such as plants or agricultural waste. This helps to reduce our reliance on non-renewable resources and helps to protect the environment.
  • Biodegradable: They can be broken down by microorganisms in the environment, which means that they do not contribute to pollution.
  • Lightweight: They are often lighter than traditional materials, which can make 3D printed objects more portable and easier to transport.
  • Strong: They can be strong and durable, making them suitable for a variety of applications.

Fire retardant

While Shelduck’s 3D Bio Pulp Printer material doesn’t yet hold formal fire resistance certifications, internal testing indicates promising fire-retardant properties. The material’s composition, combining natural fibers and starch-based binders, exhibits inherent resistance to ignition and flame propagation.

Currently, we are conducting comprehensive fire resistance tests to validate and quantify the material’s performance. These tests will involve subjecting the material to various fire scenarios, including exposure to flames, heat, and smoke. The results of these tests will inform future iterations of the material, ensuring it meets stringent fire safety standards.

We remain committed to developing a bio pulp material that not only offers environmental benefits but also meets the highest safety standards for you and your customers.

We anticipate having formal fire resistance certifications by the end of the year.

Water risistance

In its natural state, Shelduck’s 3D Bio Pulp Printer material is not water-resistant. However, it is possible to enhance the material’s water-resistance by applying a water-repellent finish. One commonly used finish is linseed oil, which forms a protective layer on the material’s surface, preventing water from penetrating.

The application of a water-repellent finish significantly improves the material’s ability to withstand moisture exposure. This makes it suitable for use in indoor and outdoor applications where occasional moisture contact is expected.

Bio Pulp and Natural Finishes

Shelduck’s 3D Bio Pulp Printer material exhibits a remarkable affinity for natural biobased finishes, including paints, oils, and waxes. This compatibility stems from the material’s inherent composition, which seamlessly integrates with these eco-friendly substances.

By incorporating natural finishes, Shelduck’s bio pulp material not only enhances its aesthetic appeal but also imparts additional properties such as water resistance, UV protection, and fire resistance. The material’s porous nature allows for the absorption of these finishes, resulting in a rich, natural patina that complements its organic form.

The range of available natural finishes, from waterborne paints to vegetable-based oils and waxes, provides designers and creators with a wealth of options for customizing their bio pulp creations. This versatility ensures that Shelduck’s 3D Bio Pulp Printer material remains a cutting-edge material, capable of fulfilling a wide spectrum of design and functional needs.

WHY OPEN SOURCE ?

Do you believe that everyone should have access to these materials too?

We are making our recipes for our 3D pulp printer open source. So, we both will accelerate the adoption of circular manufacturing and reduce the environmental impact of the furniture industry.

Our printer uses a pulp of bio materials, such as sunflower husks, hemp fiber, or waste from paprika cultivation. These materials are always 100% biodegradable.

By making our recipes open source, we hope to inspire you and others to develop their own 3D pulp printers recipes and create new and innovative products. We believe that this technology has the potential to revolutionize the furniture industry and make it more sustainable.
