  SLS 3D printing is known for producing sharp, high-quality parts with impressive precision. But like all additive manufacturing processes, it’s influenced by gravity and heat during production. While selective laser sintering manages these challenges by using unsintered powder to support the part, orientation still plays a key role in determining part strength and surface quality. Even with the near isotropic properties of SLS, your parts will often be stronger along certain axes and weaker along others. Similarly, sharp edges and precise features will appear cleaner in one direction while slightly smoothed in another. Large parts must also be positioned carefully to avoid excess heat buildup, which can cause warping. Let’s look at why orientation matters and how to position your models for the best possible results from SLS 3D printing. Why orientation matters in SLS 3D printing Part orientation is often ignored during design but it directly affects print quality. Correc...

  Design flaws cost time and missed details cost money. Prototype CNC machining helps you catch both before they cause delays and costly rework. Instead of waiting for tooling or settling for rough mock-ups, you get precision-machined parts made from production materials, giving you a clear read on how your design will perform in the real world. And it’s not just for testing. Prototype CNC machining also makes sense for short production runs when speed and accuracy matter more than volume. How CNC machining works for prototypes Prototype CNC machining combines computer-controlled manufacturing with rapid prototyping techniques, starting with a CAD or 3D model. The machine then uses cutting tools to shape the material precisely according to the design. This process produces parts with consistent quality, ensuring that each component matches the required specifications and performs as expected. Material options for CNC prototyping CNC machining works with various materials, ...
