Design for Manufacturing (DFM) regroup different approaches and Design for Additive Manufacturing is one of them. It is the ability to produce designs specifically for 3D printing. Indeed, design methods for 3D printing are quite different from traditional designs, developed for other manufacturing techniques. Creating a model for additive manufacturing, a technique consisting into building parts layers by layers, is really different from subtractive manufacturing methods or injection molding. This method enables a new way of thinking but you also have to keep in mind that 3D modeling and design for additive manufacturing are two different things. While designing for 3D printing, you create a file that has to be optimized for a 3D Printer, in order to get the correct resolution.
Before you start your project, check out our tips to design your 3D Printing models with the right tolerances, and make sure you have a good understanding of sizes and units measurements.
3D printing technologies all have their specificities, from FDM to Selective Laser Sintering or Selective Laser Melting technologies, which have to be taken into consideration during the designing process.
Design engineering is using advanced software to get incredibly optimized parts, whether it be small objects or larger parts.
3D printing and design are changing the way companies are thinking and operating!
For example, it could be the perfect approach to try out generative design.
Designing the perfect 3D model takes a specific kind of engineering. Methods such as topology optimization, parts hollowing, creation of innovative structures, or even customization, can be a real asset for your business. DfAM is not just a matter of converting an existing design, it goes further! Indeed, it is about recreating the part, optimizing it, and improving it, without the many constraints of traditional manufacturing methods such as injection molding or CNC machining. But it is not only about the part, you need to consider design supports, and it is also about the process: with thoughtful design you can reduce assembly time and the number of components to save time and money.
The work put in design is also a way to reveal the material properties of the plastic, resin or metal you use for your project! Let’s see a bit more in detail the benefits of this aspect of digital manufacturing
If additive manufacturing has so many advantages, it is mainly thanks to the design opportunities offered by this technology.
Thanks to the additive manufacturing process, it is becoming possible to create parts perfectly adapted to physical constraints. One of the main advantages of additive manufacturing is design freedom, you can create any idea you are thinking of. This printing technique also allows for the creation of interesting textures and patterns within the designs. One of the most iconic example are lattices. This technology allows to push the boundaries of manufacturing, and you will be free from the constraints of traditional manufacturing techniques, in terms of structure and design. Adapt your parts to the requirements and considerations of your business.
Design for Additive Manufacturing can make your business more adaptable. How? You can control and change everything, from the design of your parts to the quantities you are producing. 3D printing offers the opportunity to produce on-demand: you get parts when you need them. You don’t need to store your components anymore!
This whole adaptability and flexibility lead to optimization and simplification of the whole supply chain! For example, in 2017, GE Aviation revealed that it had used Design for Additive Manufacturing to create a helicopter engine with 16 parts instead of 900, with great potential impact on reducing the complexity of supply chains. Instead of using the services of 10 or 15 suppliers, they only used additive manufacturing!
Optimized products and an optimized supply-chain are a great added value to your business and will help you be ahead of your competitors. As we saw in our State of 3D Printing 2020 report, 3D printing is really seen as a competitive advantage by our respondents. Why is it so? It can help you optimize each part of your product’s life, starting from product development up to the manufacturing of high-quality finished products.
Great designs can help you save time and money! The amount of material used, the structure avoiding the assembly process, rapid prototyping, all of these aspects can help save time. 3D printing can create parts that couldn’t be made in another way, which results in better-performing components and impressive cost savings. With integrated assembly, for example, you will save time with the conception of the part and increase the efficiency of your company. You can also buy ready-made 3D Printing models.
The potential of this technology is still misunderstood and for many, the idea that this technology only fits for prototyping purposes persists. 3D printing allows to achieve things other technologies can’t.
In other words, to utilize Design for Additive Manufacturing well, one must comprehend its logic. In order to do so, involving experts who can leverage this potential is important. First to be advised, but also to make recommendations and find solutions early on. In addition to the advantages of DfAM we just saw, here are what these designers and engineers can do to your 3D models:
Topological optimization
Topology optimization is a mathematical method that optimizes material layout within a given design space for a given set of loads, boundary conditions, and constraints to maximize the performance of the system. They are often challenging to handle for traditional manufacturing techniques such as CNC machining.
Structural optimization
3D printing materials are so varied that it is easy to find the proper material for your project. When it comes to a mechanical part, the characteristics of the material is one of the main aspects to consider but do not forget about the design. To help to strengthen the material you choose, there are tweaks and design features that give your object strength and solidity, such as lattice structures. Lattice structures have high strength and low mass mechanical properties and multifunctionality. These structures can be found in parts in the aerospace and biomedical industries!
It is also possible to using Simulation for Additive Manufacturing to optimize your most complex parts, to understand where they need to be strengthen for example, and improve the capabilities of your components. Design for 3D printing is also about part consolidation and improvement of the durability and functionnality of the parts.
Be sure to check out our articles on common 3D Printing problems to avoid common pitfalls such as non-manifold geometry.
Producing a different mold for each demanded product adjustment does not only take a lot of time, but it still wouldn’t be able to keep up with the demanded preferences of all customers. This is not the case for additive manufacturing. As you only need a 3D file to create a 3D printed part, customization becomes quite easy and lead times are largely improved! You can create as many parts and customized components as you need.
DfAM can be a whole new approach for you and appear as a difficult concept. Mastering 3D printing is not always easy, whether it is to implement it in an existing process, or to start using it as a first manufacturing technique! Indeed, you might need a hand to understand better how is this technology relevant for your project, how you can make the most of it to optimize your manufacturing projects, or how you can use it to build a more efficient supply chain.

Engineering design rules for additive manufacturing ensure optimal outcomes by guiding geometric considerations, material selection, and build orientation. Key principles include maintaining consistent wall thickness, avoiding unsupported overhangs, and optimizing for specific printing techniques. Adhering to these rules maximizes part strength and minimizes defects, resulting in high-quality, functional components.
Design principles for additive manufacturing focus on optimizing geometries, material choices, and fabrication processes to enhance printability and functionality. These principles emphasize factors such as geometric complexity reduction, lightweighting, minimizing support structures, and leveraging design freedoms offered by additive processes. By adhering to these principles, engineers can create parts that are not only manufacturable but also perform optimally for their intended applications, unlocking the full potential of additive manufacturing technology.
Additive manufacturing techniques, also known as 3D printing, encompass various methods for creating objects layer by layer from digital models. Common techniques include Fused Deposition Modeling (FDM), Stereolithography (SLA), Selective Laser Sintering (SLS), and Binder Jetting, among others such as LCD/DLP or Direct Metal Laser Sintering (DMLS) Each technique has unique capabilities, materials compatibility, and applications, offering flexibility for prototyping, production, and customization in industries ranging from aerospace to healthcare.
Generative design for additive manufacturing is an innovative approach that leverages algorithms and computing power to explore numerous design iterations based on specified parameters and constraints. This process mimics nature’s evolutionary principles, generating complex and optimized geometries that traditional design methods may overlook. By integrating generative design with additive manufacturing, engineers can create lightweight, efficient, and structurally optimized components, maximizing performance while minimizing material usage and production time.
