Build Difficult Parts from A Range of Materials with Fused Deposition Modeling

 

Complex parts can make prototyping or end-use production a bit more challenging. They cannot simply be made manually, especially if you require them for low to mid-volume production as that could result in inconsistencies with the quality of the finished product. Moreover, some processes like rapid tooling and CNC machining may not be able to accommodate the complex designs. In that case, you can turn to fused deposition modeling or FDM, a 3D printing technology that is versatile and capable of building parts from a range of high-quality materials.

 

How FDM 3D printing builds parts

 

With fused deposition modeling, you take an extruding plastic filament to be fed through a nozzle in the FDM 3D printer before it is laid on a build chamber layer per layer. This way, the process is able to realize complex geometries. That said, there are restrictions on the process, particularly with overhanging features. In that case, support material will be placed to keep those features in place, and it will be removed at post-processing.

 

Build parts from robust materials

 

Because of the wide range of materials available, fused deposition modeling or FDM is ideal for low volume production and building quick prototypes. Reputable service providers offer a wide range of materials from common production materials like PC and ABC to performance plastics like nylon and Ultem. This way, the process is more versatile for building functional bits, enclosures, and housings.

 

Be sure to work with the right company

 

When it comes to fused deposition modeling or FDM, it makes sense to work only with the right service provider with a team that can support your project. Since FDM crafts components one layer at a time from a filament, the material’s diameter will determine what can and cannot be printed. You need to make sure that the minimum wall thickness is as thick as the material, and if there are holes in your design, it must be bigger than intended for 3D printing, as FDM tends to make them two to four percent smaller. Reputable service providers will review your project for free and help you with your design.

Advantages of Direct Metal Laser Sintering in Rapid Prototyping

Image
Most people associate 3D printing with making plastic parts for prototyping or end-use purposes. But with advancements in additive manufacturing technologies, it is now possible to 3D-print metal parts using the direct metal laser sintering process. Known as DMLS for short, direct metal laser sintering is a well-known industrial additive manufacturing technology similar to selective laser sintering (SLS) . However, it builds parts one layer at a time by fusing metal-based powders with a high-power laser. As such, it can realize complex designs that would otherwise be difficult to make with machining and other manufacturing technologies. Plus, it can build parts without support structures, so you spend less time post-processing. DMLS 3D printing can benefit your prototyping process in many ways. Given its speed, reliability, and cost-efficiency, it can speed up your product development and time to market to get ahead of your competition. Besides that, direct metal laser sintering c

Different Types of 3D Printing Prototypes

Additive manufacturing lets you build three-dimensional objects based on your digital drawing model. It creates a custom   3D printing prototype  by adding materials one layer at a time or by sintering or fusing powdered materials, depending on the method you use.   Technologies have come a long way and introduced more 3D printing methods to help you make prototypes quickly, accurately, and cost-effectively. Here are the most common types you may want to know. Stereolithography SLA 3D printing is among the oldest and most versatile additive manufacturing technologies. It builds the object layer by layer using a photocurable resin cured with an intense UV laser in the build platform. The result is a  3D printing prototype  with a good surface finish and optimum accuracy to the CAD. The process involves support structures to keep the material in place while printing, but these are removed afterward. This technology is ideal for making aesthetic models and bespoke or low-volume pr

Understanding the Advantages of Rapid Injection Molding

When you need prototypes or parts fast, consider having them done via rapid injection molding. The manufacturing method is particularly useful for low to mid volume production where rapid tooling might be inefficient or incapable of producing the exact results you want. Chinese injection molding companies are trusted by discerning manufacturing companies with tight deadlines and the need to test a new product in the market. With rapid injection molding, you can get the parts done quickly and efficiently using real materials. Rapid injection molding used to be reserved for mass production, where large companies would turn to manufacturers in China for an injection mold . However, it can actually also be flexible for creating high-quality prototypes. Moreover, it can be done as injection molded parts. Rapid tooling or bridge tooling is capable of delivering quality parts for low volume production requirements of up to 100,000 pieces from product resins. Think of it as an end-use
