The majority of businesses aspire to achieve sustainability but often lack clarity on where to begin. Many perceive adopting sustainable practices as a daunting task, believing it necessitates a complete overhaul of their production processes to make a significant impact. However, let me assure you that this is not the case.
So, where should you start your journey towards creating more sustainable product design and manufacturing processes?
To genuinely embrace sustainability, focus on making design decisions at the outset. Designing for repair, reducing material usage, refurbishment, remanufacturing, recovery, reuse, and recycling is crucial. It requires a holistic approach that considers a product’s environmental impact throughout its lifecycle.
Over 80% of a product’s environmental impact stems from design decisions made early on.
Here are three ways design changes can drive sustainability:
Sustainability in Design for Dematerialization
Dematerialization, or material usage reduction, emerges as a crucial strategy for sustainability, aiming to reduce material consumption and weight without sacrificing strength and durability. Leveraging cutting-edge technologies like Generative Design, engineers can optimize designs to use only the necessary amount of material, tailored to specific loads and constraints of each application.
Creo Simulation Live offers a seamless platform for quickly assessing how different materials or reduced material usage affect design performance, enabling adjustments earlier in the design process.
Moreover, with solutions like Creo AMX, designers leverage additive manufacturing capabilities to build structures in the most efficient direction, generating automated supports, and showcasing the potential of lattice structures.
These innovations not only allow for a material reduction but pave the way for lighter, more sustainable products that maintain the required level of performance. As we continue to prioritize dematerialization in manufacturing, we edge closer to a future where sustainability and efficiency are seamlessly integrated into every aspect of product development.
Sustainability in Design for Waste Reduction
Designing for manufacturability and minimizing material waste, such as through minimal stock allowance, ensures efficient use of resources from the outset. By leveraging die casting for near-net shape production throughout the manufacturing process, material waste is significantly reduced to maximize material utilization and minimize scrap generation.
Additionally, utilizing numerically controlled (NC) strategies optimized for fast machining and lower energy consumption, such as high-speed machining (HSM) roughing and finishing, contributes to waste reduction and energy efficiency.
Moreover, designing for ease of service and assembly extends product lifespan and reduces the demand for new products. While some parts of a product may wear faster than others, creating products for easy disassembly eliminates waste because you do not have to throw away the entire product to extend the lifespan.
Accurate documentation of assembly and disassembly instructions empowers users to maintain and repair products, minimizing waste and promoting a more sustainable approach to product lifecycle management.
Sustainability in Design for Energy Efficiency
Engineers globally actively address questions such as, “Can we reduce noise and unneeded energy consumption in design?” and “Can we make our design more thermally efficient?” to pave the way for eco-friendly innovation.
Their goal is to pinpoint areas where energy is wasted, but don’t have the most efficient tools to accomplish that task. Modal analysis and thermal analysis enable more streamlined and environmentally conscious designs. Additionally, tools like Creo Flow Analysis optimizes flow efficiency to ensure that products operate with maximum efficiency, minimizing energy requirements without sacrificing performance.
Furthermore, selecting materials that demand less energy to manufacture and recycle adds another layer of sustainability to the design process and reduces the overall environmental impact from production to end-of-life disposal. Through these proactive measures, energy-efficient product design becomes a tangible pathway towards a more sustainable future.

By partnering with EAC for solution identification and utilizing PTC’s comprehensive Creo design tools, companies can pave the way for a sustainable future while improving their bottom line. Let’s talk about how EAC can help you identify solutions to help your company embrace sustainable design practices today!
EAC’s been in the engineering and design technology world for a long time. Over the years we’ve carefully cultivated our product portfolio to meet the ever-changing needs of people and companies that design, manufacture, and service products. Our partnerships with PTC and ANSYS allow us to offer a few different design simulation and analysis solutions to our customers.
Design simulation, Computer Aided Engineering (CAE), Finite Element Analysis (FEA), Computational Fluid Dynamics (CFD), and many other terms all fall into the “simulation and analysis” bucket. These tools help engineers and designers create virtual prototypes of their products. This helps groups rapidly prove, or disprove, design ideas in a digital space – reducing the time and money spent on physical prototypes, and increasing confidence in designs.
“If you’ve seen one, you’ve seen ‘em all” does not apply to simulation software. Different tools offer different benefits, accuracy, speed, and ease-of-use. Here’s a quick overview of some of the tools we offer. Contact our sales group to learn more about pricing, full capabilities, and packaging.
Option 1) PTC Creo Simulate
Simulate is a fantastic tool that’s fully integrated into PTC Creo Parametric CAD software. It offers fantastic meshing capabilities and accurate simulation results directly within a user’s familiar CAD software interface. All you need to do select the PTC Creo Simulate tab and you’re off and running. This is great for designers and engineers looking to test the stresses and loads under which a product will operate in ‘real world’ conditions. Based on your simulation and analysis results, you can either fix design flaws or forestall them. If you’re already using PTC Creo you should explore PTC Creo Simulate. Because, why would you ever manufacture a product without testing and analyzing it first? Creo Simulate comes in two flavors – Simulate and Advanced Simulate. They come with two different price points. One or the other might be the best option for your company. It really comes down to whether you need to simulate materials with linear or non-linear properties.
Option 2) ANSYS Discovery Live
ANSYS Discovery Live blows my mind. This tool was released in late 2017 and delivers functionality never seen before. Discovery Live uses ANSYS Discovery SpaceClaim to pull in IGES, STEP, and CAD models. Then the interface guides users through applying materials and some constraints – and Boom! It runs the simulation…in real-time…right in front of you. I’m talking about the ability to run wind-tunnel testing in real-time! Discovery Live is different from PTC Creo Simulate and most other simulation tools. It uses the Graphics Card (GPU) to run the simulation. This means it doesn’t occupy your core processor and RAM to while solving. You get better computer performance and instantaneous results for structural, thermal, fluid flow, wind tunnel, structural/fluid interaction, and more. Discovery Live is a great tool for engineers and designers that want to test a lot of design options quickly. The price is incredibly reasonable for a tool this powerful. You can see pricing and compare Discovery Live to AIM here.
Option 3) ANSYS Discovery AIM
Sometimes simulating real-world conditions requires more features and control than tools like PTC Creo Simulate, Solidworks Simulation, or Discovery Live might offer. ANSYS Discovery AIM is a great option when that’s the case. ANSYS Discovery AIM is a “multi-physics” simulation tool. What does that mean? Multi-Physics or Multiphysics refers to the ability to combine properties and solvers to simulate product usage. “Physics” in the simulation world refers to the kinds of simulation you are running – e.g. electromagnetic, thermal, structural, radio frequency, fluid flow, etc. AIM is a workflow driven multi-physics tool. It guides users through the steps necessary to complete a successful simulation. This is the perfect option when companies want a robust solution, but may not have experienced analysts on staff. Much like how PTC Creo Simulate maintains a familiar interface to make simulations easier; AIM uses guided workflows to make detailed upfront simulation accessible to engineers and designers.
Option 4) Dedicated ANSYS analysis software
When product simulation and analysis goes to the next level you need the ANSYS flagship products. These are sometimes known as the ANSYS Workbench products. Unlike PTC Creo Simulate or the Discovery software, each of these tools focus on one area of simulation…and deliver results you can take to the bank (or the regulatory agency). They are more complicated and come with a higher price point, but the results are unmatched. ANSYS’ comprehensive software suite spans the entire range of physics, providing access to virtually any field of engineering simulation that a design process requires. Organizations around the world trust ANSYS to deliver the best value for their engineering simulation software investment. If you need to test a specific physic – fluids, structures, electronics, semiconductors, or embedded software – this is the option for you. Contact us to learn more about a specific solution’s pricing and functionality. Also, if you’re a start-up make sure you ask us about special offers available through the start-up/entrepreneur program.
So there you have it. My layman’s take on a variety of simulation options. I hope you found this helpful. Please reach out to us if you have any questions or would like to see a demonstration of any of these tools.
