Here’s Why You Should Switch to Conformal Cooling

 

With growing use of 3D printing in increasing number of industries, the need for a swift and efficient cooling design is high. The injection molding industry is increasingly seeking more advanced, even non-conventional cooling designs. Hence, conformal cooling channels are becoming the norm in the injection molding industry.

DMLS Creates Conformal Cooling Channel Conveniently

Despite the initial excitement, many industrial leaders avoided using conformal cooling technology up until five years ago because the technique used to be difficult and expensive. However, advances in technology have made Conformal Cooling design more affordable and easy to use.

Direct Metal Laser Sintering (DMLS) can efficiently mold parts with intricate outer and inner geometry. Thus, creating conformal cooling channels and tooling inserts simultaneously.

DMLS is the Ideal Solution to Create Conformal Cooling Design

DMLS is a type of additive manufacturing (AM) technology. It uses a thin but powerful laser beam to melt and mold metal powder together and form parts as described in 3D CAD models. This is an incredibly powerful way to create complex designs by using layers of material as thin as 40 µm. 

The DMLS technique uses conventional bronze alloy mixed with incredibly strong EOS Maraging Steel MS1. EOS Maraging Steel MS1 is a fine powder made from grounding pre-alloyed ultra-high tensile strength steel. This advanced metal alloy allows mold-makers to create tools for large-volume applications.

Despite its incredible advantages, there are still numerous injection molders and mold-making experts who seem comfortable with conventional cooling methods. However, there are several convincing reasons that can compel these molding experts to consider switching to the more advanced and efficient conformal cooling design using DMLS.

Advantages of Using DMLS for Creating Conformal Cooling Design

DMLS helps to avoid the need for secondary drilling in the finished product. In addition, it creates intricate Conformal Cooling channels that are set flush against the mold cavity and to make channels in hard-to-reach places, which is not possible with conventional cooling channels. Also, the conformal cooling channels can be created in different shapes which promote efficient coolant flow or excellent heat dissipation. This is possible due to the extremely precise molding that DMLS offers.

Let’s check out the two top reasons that make conformal cooling channels with DMLS technique far more effective and efficient than conventional cooling:

Everything you need to know about Selective Laser 3D Sintering

  Selective Laser Sintering (SLS) uses the “sintering” technique in which a powdered raw material is heated and compressed simultaneously to form a solid, specific mass. Sintering works by compressing the powdered raw material through a combination of heat and pressure. Although sintering does not outright melt the powdered raw material, it applies just enough heat for the atoms to separate and diffuse together once more. Benefits of using Selective Laser 3D Sintering Selective Laser 3D Sintering , also known as, SLS 3D printing, or simply as SLS, is the go-to method for batch production of customized components and rapid prototyping. This technique has found incredible use in industrial-scale applications thanks to its reliability, precision and faster production process. Let’s take a look at some of the express benefits of using Selective Laser 3D Printing technique in manufacturing: 1 – No support structures are needed One of the major benefits of using SLS 3D printing is th

What Makes SLS 3D Printing Better than Others?

  Selective Laser Sintering, or SLS, remains one of the most popular 3D printing techniques in use today. It melts the raw material and arranges it layer by layer to make the shape entered described in the CAD file. Mostly, grains of the thermoplastic polymer is used as the raw material in SLS 3D printing. Today, selective laser sintering has become increasingly popular for producing prototypes and functional parts of machinery in small batches. The reasons behind the popularity of SLS printing are its extensive freedom in designing, higher accuracy in production, and consistent quality with functional physical properties. SL S  3D Printing becomes the optimal solution for prototypes and spares part manufacturing when the designer is aware of the capabilities and limitations posed by the technology. What important characteristics of SLS 3D Printing should a Designer know? If the designer is aware of the extent of freedom and limitations of the 3D printing technique, then they can succ
