Why choose "3d printing metal" over casting

Did you know that 3D printed aluminum is stronger and more durable than cast aluminum? 

3D printing has today taken a large place in Swedish industry, above all because it is often very cost-effective and more environmentally friendly than usual traditional manufacturing methods. Turning and milling generate a lot of waste during the machining process and casting often requires several prototypes or molds before the final shape has been produced. You can also 3D print in very hard materials such as titanium which otherwise require special machines and tools to cope. 

The advantages of choosing 3D printing over casting

Choosing metal 3D printing instead of casting has several advantages. Here are some reasons why metal 3D printing can be a beneficial option: 

Design freedom

3D printing in metal enables the creation of complex geometries and details that can be difficult to achieve with casting. It gives the designer a high degree of freedom to create complicated shapes and structures. 

Rapid prototyping 

Metal 3D printing allows for rapid prototyping, which can be beneficial for quickly iterating and testing different design concepts before moving on to production. 

Less material waste

Casting often means that a certain number of prototypes or molds are required before the final shape is ready. This can lead to significant material waste. With 3D printing in metal, objects can be manufactured directly from a digital model without having to create molds, which reduces material waste. 

Less need for tools

Casting requires the manufacture of molds and tools, which can be a time-consuming and expensive process. With metal 3D printing, complex parts can be produced without the need to manufacture expensive molds, reducing the initial investment cost. 

Customized and unique products

3D printing in metal makes it possible to manufacture customized and unique products with high precision. It can be particularly beneficial for manufacturing prototypes, spare parts or custom components.

ESD står för elektrostatisk urladdning (Electrostatic Discharge), vilket är en plötslig överföring av elektricitet mellan två elektriskt laddade objekt orsakad av direkt kontakt eller genom ett elektriskt fält. Detta fenomen kan orsaka skador på elektroniska komponenter och kretsar, eftersom de ofta är känsliga för små laddningar. För att skydda mot ESD-skador används ofta antistatiska material, jordningsmetoder och andra förebyggande åtgärder inom elektronikindustrin.

A CAD program, which stands for "Computer-Aided Design," is an important component when it comes to ordering 3D prints for industrial purposes. CAD programs are specialized software used to create detailed and accurate digital models of objects, components or prototypes. These digital models serve as basic blueprints or designs needed to produce physical objects using 3D printing technology.

.STL (stereolithography) is a file format used to represent 3D geometry, especially surfaces made up of triangles. It is a common format in 3D printing and is used to describe models to be printed in 3D printers.

.STEP (Standard for the Exchange of Product Data) is a standard for exchanging 3D models and product data between different CAD (Computer-Aided Design) programs. It is a common format in industry and is used to transfer detailed 3D models of components and products.
