Some Points You Should Know About FDM 3D Printing

Fused Deposition Modeling (FDM) is among the most commonly used and versatile 3D printing technologies. It works by building parts from an extruded plastic filament material through a nozzle, and then laying that plastic down on the build chamber layer per layer. FDM 3D printing can create complex geometries, but there are restrictions in the process that requires support material for any overhanging features. That said, the supports are removed post-process. Read on to learn more about this additive manufacturing method:

 

Different materials available

 

Fused deposition modeling FDM can print in a wide variety of materials. The selection typically includes PC and ABS plastics, as well as performance materials like nylon and Ultem. That makes the process versatile for building a wide range of prototypes and for low volume production of objects and parts like enclosures, housings, and functional bits.

 

Efficient and cost-effective

 

As FDM 3D printing is widely available, it is typically considered cheap, while being able to efficiently produce high-quality results. The process can also be scaled, so it should suit most types and sizes of projects. Only the movement of every gantry is considered the main constraint in the build area’s size. By lengthening the gantry rails, the build area can be bigger.

 

How it differs from other 3D printing technologies

 

Rapid prototyping service providers offer a wide range of 3D printing technologies. Besides fused deposition modeling FDM, they provide SLA 3D printing, which cures liquid resin with a highly precise laser to create a part one layer at a time. If your project does not have any fine or intricate details and it won’t be used for manufacturing or engineering applications that emphasize the importance of material properties, FDM 3D printing can be a good choice. Otherwise, you might want to consider SLA 3D printing.

 

It struggles to print holes

 

Does your project have holes? FDM tends to print them smaller by around two to four percent. So, you will have to design them slightly larger, or you ask the manufacturer to drill to size at post-processing. They can also install inserts for any holes.

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
