Metal 3D Printing in Brief

Metal 3D Printing in Brief

Metal 3D printing or Metal Additive Manufacturing is a revolutionary technology which produces components directly from 3D CAD data. The 3D CAD data is cut into numerous sections, and these sections are printed one over the other to get the final component.

A major advantage of the technology is to produce parts with complex geometries which are difficult to manufacture through conventional techniques. 3D Printing offers the flexibility to design parts for their functionality rather than designing the parts for their manufacturability.

Metal 3D printing is used to manufacture one off prototypes, small batch production parts, series production parts and die and mould repair. Different Metal AM methods such as Powder Bed Melting, Binder Jetting and Direct Energy Deposition have their own advantages.

At Rapid DMLS, we use the most popular technique of Direct Metal Laser Sintering which yields the best part properties and has the ability to produce complex geometries.

Metal 3D printed parts used in space crafts

Space

The heavier the weight of launch vehicle, more fuel is required and therefore, more cost. With the help of metal 3D printing, weight of the launch vehicle can be decreased drastically. High performance alloys like Inconel which are difficult to machine and find application in rocket engines, are processed much easily through 3d printing.

Metal 3D printed parts in automotive industry

Automotive

Although the Auto industry needs parts in high quantities, AM has applications for Automotive. When developing a new product, all the design variants can be printed and the best among them can be chosen. With the entry of electric vehicles, ergonomic and lightweight parts can be manufactured which increases the efficiency of the vehicle.

Metal 3D printed parts in tooling

Tooling

Unlike straight cooling channels achieved by drilling, AM produces optimized cooling channels that closely conform to the surface of the mold cavity. This enables for faster heat transfer between the injected material and cooling fluid, resulting in rapid uniform cooling of the injected part, thereby reducing the cycle time and producing better quality parts.

Usage of metal 3D printing in general engineering

General Engineering

Most of the engineering components can be made feasible for Metal 3D printing. Custom jigs and fixtures can be additively manufactured in a very short lead time. General engineering applications includes prototype parts, small batch production parts as well as custom made parts used to improve an existing process.

New Material Development

Out of the plethora of metal alloys available in bar stock form, only around 8 to 10 metal grades are currently available for DMLS. Based on your specification, we can get powders of a certain alloy made through Gas Atomisation. This powder then undergoes extensive research at our facility.

Parameter Optimization

Based on your application and requirement, we optimize the process parameters for desired part properties. Requirements could be a better surface finish, higher productivity or a mixture of both. Our R&D activity includes experimenting these parameters and testing it for the desired output.

General FAQs

General FAQs

Direct Metal Laser Sintering (DMLS), Selective laser Melting(SLM) and Direct Metal Printing(DMP) are all the same. It is basically Powder Bed Melting process using a laser source. Different Machine Manufacturers use different names to promote their brand.

Our machine has a build volume of 250mm x 250mm x 300mm in the x,y and z directions respectively. So, any component within that envelope can be built. However, bigger parts can be cut into sections and these printed sections can be joined through welding to get the final product.

Since it is a Powder Bed process, it is currently impossible to print 2 different alloys simultaneously. However, we can print with a certain alloy up to some height, and then continue printing with a different alloy from that height.

The virgin powder after its first use goes through a sieving process to separate condensate material from the good powder. The condensate is scrapped and the sieved powder is used for the next build. A ball –park value for material wastage can be taken as 5% of the part weight.
