Manufacturing Technology
Industrial 3D Printing Technologies
Our 3D printing white paper examines the various additive manufacturing technologies—SL, SLS, DMLS, FDM, PolyJet, and others—being used by today’s product designers and engineers to build prototypes and even functional, end-use parts.
Overmoulding and Insert Moulding
Overmoulding and insert moulding are regularly used to manufacture multi-material components for applications in industries such as medical and health care, automotive, and electronics. But it’s only recently that it also became a viable and cost-effective prototyping method. This white paper offers a primer on overmoulding and insert moulding and how they can be used both for prototyping during development and on-demand production.
Data, Digital Threads, and Industry 4.0
Just like how the steam engine led an industrial revolution centuries ago, software and data are changing the way we manufacture today. In this white paper, learn how industry-leading companies are accelerating the product development cycle through the use of new technologies and data analytics.
Strategic management of your manufacturing supply chain is critical during product development and life cycle planning. This white paper illustrates how on-demand manufacturing can be used to reduce financial risk and accelerate speed to market through the implementation of supply chain safeguards.
In the drive to accelerate new product development and time to market, the pressure to validate a design can be intense. Increasingly, smart manufacturers—and their design teams—are looking ahead, past the prototyping phase of the product design process, and are thinking in terms of the end product and its required performance characteristics.
3D Printing for End-Use Production
Industrial-grade 3D printing has developed a solid reputation as a reliable process for prototyping parts. More recently, 3D printing has emerged as a potentially viable production option. This white paper offers an analysis of additive manufacturing technologies that may be redefining 3D printing as a manufacturing method for end-use parts.
Each manufacturing rapid manufacturing process comes with its own advantages and disadvantages during prototyping. From 3D printing to CNC machining to injection moulding, our white paper is a technical look at different manufacturing processes. It lets you weigh the benefits of each, so you can focus on a process best suited for your project.
Part Design
Designing for Mouldability: Fundamental Elements
Whether you’re new to the injection-moulding process or a veteran of manufacturing, our comprehensive Designing for Mouldability white paper is a quick reference guide to wall thicknesses, surface finishes, tolerances, materials, and other thermoplastic moulding insights. It’s a thorough look at injection moulding that might just provide a few tips to help you make better parts.
Designing for Mouldability: Complex Features
In our second volume on designing parts for mouldability, we dig deeper into some of the more complicated design challenges that product designers and engineers face. If your part has complex features that require undercuts and through-holes, see how the use of side-actions, sliding shutoffs, and pickouts can be used mould those features.
There are a lot of factors that can affect the cosmetic appearance of injection-moulded plastic parts. Our white paper on cosmetics addresses the importance of part geometry, material selection, and mould design in minimising or eliminating cosmetic flaws like sink, knit lines, flash, burn, and other issues that can arise during moulding. Knowing the solutions to cosmetic issues early can improve the final appearance of your injection-moulded parts.
CNC machining has been around for decades, and for good reason. It’s one the fastest manufacturing technologies for prototypes and end-use parts. Want to learn how you can optimise your product development cycles with CNC machining? This white paper shares how to design for the subtractive manufacturing process, select the best material for your application, and streamline new product development.
Scientific Moulding Helps Ensure Repeatable Part Function
How to create consistency in injection moulding part production through detailed, scientific processes. This guide covers the basic steps in setting up this process.
Combining Part Assemblies with Additive Manufacturing
This guide explores how to find opportunities to move multi-part assemblies toward consolidated additive manufacturing in direct metal laser sintering (DMLS), selective laser sintering (SLS), and multi jet fusion (MJF), but also how to achieve a result that is more cost effective and higher performing than other manufacturing methods.
Material Considerations
This industrial 3D printing white paper explores the properties of thermoplastic and metal materials available with stereolithography, selective laser sintering, and direct metal laser sintering technologies. It also includes a quick-reference guide of material attributes that can steer you toward the proper grade.
There are more than 85,000 commercial options for plastic materials listed in materials databases. Needless to say, narrowing down that extensive list of materials can sometimes seem like a formidable task. Our white paper provides a technical observation of thermoplastic resins and their properties for engineers who want to quantitatively analyse a part; determine loads, stresses, strains, and environments; and make material decisions based on the analysis.
Our white paper on liquid silicone rubber (LSR) discusses the injection-moulding process of the elastic material and offers guidelines to improve moulded LSR parts. While there are some shared similarities to thermoplastic injection moulding, LSR is a thermoset material with a unique set of design characteristics.
Material Alternatives for Plastic Injection Moulding
Navigating supply chain issues is a constant challenge, especially in times of material shortages. So we looked at the more commonly used materials and compiled a list of substitution options that can serve well as replacements. Choosing which ones to use will depend on material properties and the intended functions of your parts. Each section delves into those material properties and reasoning behind the alternative recommendations to provide insight into additional resin options.
Material hardness testing is a crucial method for assessing the resistance of materials to deformation or penetration. This white paper discusses various aspects of material hardness testing, including methods, suitability, advantages and disadvantages of hard materials, and common treatments to enhance material hardness.

An Engineer’s guide to understanding the state of the art in hardware, materials, and the future of robotics manufacturing.
Automotive: Reducing Component Weight
Government regulations and market-driven redesign initiatives are driving automakers to develop increasingly fuel-efficient vehicles. One way to do that is through reducing the weight of components in cars and trucks. This white paper looks at lighter materials, like magnesium and aluminium, as well as plastic alternatives that can lessen the load. We also discuss different design considerations to help reduce part weight and the rapid manufacturing processes to get there fast.
