BIODEGRADABLE AND/OR COMPOSTABLE BIOBASED POWDERS FOR ADDITIVE MANUFACTURING, AND METHODS FOR THE USE THEREOF - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240294796 titled 'BIODEGRADABLE AND/OR COMPOSTABLE BIOBASED POWDERS FOR ADDITIVE MANUFACTURING, AND METHODS FOR THE USE THEREOF

The present invention focuses on biodegradable and/or compostable biobased particulate compositions for additive manufacturing, including polyhydroxyalkanoate (PHA) powder.

• The particulate composition and/or the PHA powder must have a free bulk density greater than 0.30 g/ml and a sinterability region of more than 15 degrees Celsius.
• Methods of manufacturing such compositions for use as powdered build material in additive manufacturing processes are also covered.
• Additive manufacturing processes utilizing these compositions are described, along with the printed articles produced from them.

Potential Applications: - Sustainable 3D printing materials - Environmentally friendly manufacturing processes - Biodegradable products in various industries

Problems Solved: - Reducing the environmental impact of additive manufacturing - Providing a more sustainable alternative to traditional materials - Meeting the demand for eco-friendly products

Benefits: - Lower carbon footprint - Biodegradability and compostability - Versatile applications in different sectors

Commercial Applications: Title: Eco-Friendly 3D Printing Materials for Sustainable Manufacturing This technology can be used in industries such as: - Healthcare for biodegradable medical devices - Packaging for eco-friendly packaging solutions - Automotive for sustainable parts production

Questions about Biodegradable and Compostable Biobased Particulate Compositions: 1. How do these compositions compare to traditional 3D printing materials in terms of performance and cost?

  These compositions offer similar performance to traditional materials while providing environmental benefits, but cost-effectiveness may vary depending on factors like scale and availability.

2. Are there any regulations or certifications required for using biodegradable and compostable materials in manufacturing processes?

  Depending on the industry and location, there may be specific regulations or certifications needed to ensure compliance with environmental standards and safety requirements.

Original Abstract Submitted

the present invention is directed to certain biodegradable and/or compostable biobased particulate compositions for additive manufacturing, such as those including a polyhydroxyalkanoate (pha) powder, wherein the particulate composition and/or the pha powder possesses (a) a free bulk density, as determined by astm d1895-96, of greater than 0.30 g/ml, and (b) a sinterability region of greater than 15 degrees celsius. also, the invention is directed to certain methods of manufacturing such biodegradable and/or compostable biobased particulate compositions useful as powdered build material for additive manufacturing processes. in addition, the present invention is directed to additive manufacturing processes utilizing the biodegradable and/or compostable biobased particulate compositions elsewhere described, along with the articles printed therefrom.
