Composition for Additive Manufacturing Processes

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a polymer-based composition specifically formulated for use in additive manufacturing (3D printing) processes, especially powder bed methods like laser sintering. The composition solidifies from a melt into a substantially or fully amorphous form, providing a wider processing window due to a high melting temperature and tailored thermal properties. The invention also details a process for making the powder, improving its flow behavior and mechanical properties of resulting printed parts, and is suited to producing high-precision, mechanically robust, and dimensionally accurate 3D objects.

Use CasesContent extracted from patent full text and abstract with AI.

• 3D printing of prototypes and end-use parts in industrial applications using powder bed fusion (e.g., selective laser sintering or multi-jet fusion)
• Manufacturing complex, low-volume or custom components for aerospace, automotive, and medical devices
• Production of individualized items such as hearing aids, dental prostheses, or customized functional parts
• Rapid manufacturing of spare parts with high mechanical and thermal performance requirements
• Additive manufacturing of dimensionally stable, low-porosity, high-strength objects for machinery and electronics

BenefitsContent extracted from patent full text and abstract with AI.

• Wider processing (sintering) window allows more stable and flexible 3D printing, reducing risk of errors and improving print quality
• High melting temperature of the powder enables better mechanical strength, resistance to heat, and long-term part stability
• Produces amorphous (rather than crystalline) polymer parts, lowering risk of warping, shrinkage, and delamination
• Enables creation of parts with high density and low porosity, improving strength and durability
• Improved powder flowability and printability ensures consistent layer deposition and reliable process automation
• Versatile compatibility with various powder bed additive manufacturing methods
• Allows for the addition of functional additives or fillers to customize mechanical, thermal, optical, or flame-retardant properties
