  When production tooling is projected to be too costly and might take too long for your project, you might want to consider another option: vacuum casting in China. The service will deliver high-quality urethane parts that can be used for prototyping or for low volume production. China is among the leading countries trusted by international clients for low-cost and time-saving urethane casting.   There are many companies offering the service today, but not all of them will care about your best interests. So, it’s important to be discerning and choose only a reputable manufacturing partner you can rely on. Here are some tips to help you find them:   Look them up   Online is a good start. Find out how long they have been in business. Some have been around for over 10 years now, and they have extensive experience in working with a wide range of international clients. As you are getting to know the company, find out who owns and runs it. You might want to consider a rapid prot

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 availa

Rather than building your product models or prototypes using traditional methods, you may want to hire a reliable SLS 3D printing service to ensure accurate and higher-quality results. The more you should consider that if you need your prototypes to be functional, so you can properly evaluate their design and verify their function. You just need to prepare your 3D CAD file and have the service provider review it to find out if this 3D printing method is right for it!   About SLS 3D printing   Selective Laser Sintering (SLS) is a 3D printing technology that is trusted by manufacturers, product designers, and engineers from different industries for its ability to create functional and durable prototypes and parts. It can also be used for creating low-volume end use parts with the same features. It works by fusing powdered nylon material together one layer at a time using a precision laser. A good SLS printing service can also produce parts with isotropic behaviour and mechanical

Additive manufacturing technology is not just about producing parts. There is a 3D printing technology that can print metal parts, too, and it is known as direct metal laser sintering (DMLS). In direct metal 3D printing, metal powders are fused by precision lasers one layer at a time to build the part. It creates the component based on the 3D CAD file, which determines the complexity of your design.   How does it work?   First, a thin layer of metal powder must be distributed evenly across the build chamber. Then, a CAD file must be ready, so the precision laser will follow it when heating and fusing metal powders to replicate the design. The process is repeated for every layer until the desired size and shape of your product is achieved.   When you think about the direct metal 3D printing process, its advantages are likely to make more sense for your prototyping needs. Here is an overview of its benefits:   Streamline your production   Through DMLS, several steps

Do you have a metal fabrication project that requires a reliable and solid enclosure? That may be the case when you are designing one for a sensitive machine, storage cabinet, or any other crucial application. The easiest choice is the sheet metal enclosure, which can be fabricated using specific techniques and made out of any specific metal of your choosing. Here, we’ll discuss five tips to help you make an informed decision about this part and getting it crafted by a professional:   1. Consider your design   Do you need a sheet metal enclosure to be functional or is it merely serving as a prototype this time? Does it have complex geometries? Getting it made using direct metal laser sintering may be cost-effective and quick. DMLS is a 3D printing technology that can craft complex geometries and shapes that would be either incredibly costly or impossible to make using other conventional methods. This additive manufacturing method is also practical if you want to produce lightw
