Design & Development Case Studies & White Papers

  1. Part Marking Using Pad Printing And Laser Engraving

    When designing parts for injection molding, you may need to consider finishing options, which can help improve a part’s mechanical properties, enhance surface finishes, facilitate the final assembly process, or just further customize your part or parts.

  2. PEEK, PEI, LSR, And Other Material Options For Medical Prototyping

    Developing medical device parts is a high-stakes process, and material choice is an important decision. Five strong contenders include PEEK, PEI, and PPSU; polycarbonates; medical-grade liquid silicone rubber; and 3D-printed titanium and ABS-like WaterShed XC 11122. 

  3. Actionable Insights For The Pharmaceutical And Biotech Industry

    Product Lifecycle Management (PLM) relies primarily on past performance to predict future results and help evaluate performance. Unfortunately, project managers still lack useful analysis and forward-looking capabilities to predict and ensure success. Enhancing project management with analytics creates project intelligence, offering the opportunity to shift from a task-based activity to a performance-driven one. This article discusses the importance of using actionable insights within pharmaceutical and biotech industries and the benefits that they provide.

  4. Use Color Matching To Customize Molded Parts

    Product designers often need their manufacturing suppliers to produce plastic injection-molded parts that are Pantone color-matched to company specifications. Protolabs' injection molding service offers custom color matching on customer-provided Pantone numbers and on customer-provided part samples.

  5. A Novel Method For Chemical Recycling Of PLA Under Mild Conditions

    Using the newly discovered process, different grades of PLA can be removed from a stream of commingled plastics and broken down to give high value chemicals. 

  6. Advancing Bioabsorbable Scaffolds With Polymer Technology

    Treating CAD with bioresorbable vascular scaffolds (BRS) is considered by many to be the “next revolution” in endovascular therapy. This paper presents the basics of BRS technology, its processing and manufacturing challenges, and its advantages in use with polymer technologies.

  7. Tie Layer: A Breakthrough Solution To Catheter Failure

    Product engineers at catheter manufacturing companies will be only too aware of the problem of delamination – the separation of material layers within the catheter.  The solution lay in the design of an additional material layer between the inner etched PTFE liner and the outer jacket material of the catheter. This extra layer would deliver the crucial adhesion required to prevent delamination, ideally without increasing the outer diameter of the finished catheter.

  8. Focus On Polyimides For Medical Applications

    Polyimides (PIs) occupy a particular place in commercial plastics because of their ability to tolerate and function in extremely high temperatures. They are also well known for other beneficial properties including insulating capability, chemical resistance, and excellent mechanical attributes. With their combination of properties and their ability to be tailored toward application specifics, polyimides offer some of best options for performance in high heat and other difficult environments. This white paper provides a brief overview of polymide properties, their structure, and how they are synthesized for use in extreme environment applications.

  9. How Design Aids Lead To Success

    There are many aspects to the process of creating a wide variety of products, but they all have something in common at the beginning. You will need to understand this common element because it's the key to a successful design.

  10. Protecting Implantable Medical Devices From Moisture With Desiccant-Infused Silicone

    Moisture can be harmful to implantable medical devices that operate with electronics. The excess moisture can cause oxidation and dendritic growth in metal parts and wires, and can cause many problems including a fatal electrical shortage or complete device failure as worst case scenarios.
