The Benefits of Automated Conveying in Rotational Molding Plants
How does craft beer relate to our industry? • Companies have the same equipment, but use it differently based on the products that their customer’s demand. • Both industries are very open and collaborative. People freely share their operational ideas and innovations. • Key characteristics are closely monitored in both industries. • Particle size distribution matters. It causes molding issues in roto, and prevents you from getting your grist into the mash in brewing. • The operational set-ups are dependent on product mix. • Both processes are hot and physically demanding. • Both industries have a limited number of raw materials, and it’s up to the designer to use those to create different and wonderful products. • Both industries have to innovate to succeed.

Mechanical Properties Of Reinforced Compounds For Large Format Additive Manufacturing (Lfam)
This is a technical marketing presentation about "Mechanical Properties of Reinforced Compounds for Large Format Additive Manufacturing (LFAM)"
Best Practices For Design Of Plastic 3D Printed Parts
When designing plastic parts that are to be 3D printed, the designer must consider certain unique characteristics of the plastic printing process. These characteristics imply that different techniques must be used during design of 3D printed plastic parts than what might be used during design of injection molded plastic parts and design of 3D printed metal parts. This session will discuss some of the unique aspects of designing plastic parts for 3D printing as well as unique aspects of the preparation for printing these parts.
Processing Considerations: Cellulose Nanocrystal Thermoplastic Urethane Filament Production
Cellulose nanocrystal (CNC) thermoplastic urethane (TPU) nanocomposites offer a wide range of unique thermal and mechanical properties. This paper focuses on solution mixing and melt processing considerations for producing cellulose nanocrystal (CNC) thermoplastic urethane nanocomposite filaments which can subsequently be printed using a fused filament fabrication (FFF) machine.
Case Study: The Hp Printer That Prints Itself
The case study will provide the roadmap as to how HP’s MJF technology will be used to manufacture components for manufacturing. This case study will go through the different phases of the process that enabled 3d Printed content for the next series of MJF 3d Printers. Including the steps of Assessment, Design, Economics, and manufacturing.
Hp Multi Jet Fusion For Manufacturing
Multi Jet Fusion is new to the additive manufacturing industry, but the capabilities enable the process to be used in the manufacture of production quality components. This technical session will present a deep dive into the technology and illustrate how it achieves the value proposition and how to unlock value with the technology. Additionally, applications that are enables by Multi Jet Fusion will be discussed.
Dimensional Accuracy And Design Tips For Composite Parts Made By The Fdm Process”
Fiber orientation can create layers with oriented fibers that behave as pseudo-plies, analogous to more conventional continuous fiber or fabric reinforced composites. Warp and distortion of several part geometries produced from carbon fiber composites made on a Stratasys FORTUS 450mc printer are analyzed as a function of the pseudo layup and structures used to fabricate the parts. Practical solutions for mitigating warping and balancing physical properties are proposed.
