What types of metals and alloys can you print with?
There’s a broad range of materials that can be manufactured through AM, including nickel, titanium, steels, and many others. We welcome you to visit our website to learn more, or get in touch with one of our leading experts in metal powders or additive manufacturing!
Which alloys do you use?
We supply the major part of the available powder alloys for AM. This includes alloys that are Fe-based, Ni-based, Co-based, Al-based, Cu-based – and more.
How far have we come with 3D printing of super alloys?
Globally there are some applications that are used, the major part in non-rotating applications. There are still a lot of developmental activities ongoing to implement more super alloy-based applications produced via AM.
Overall part dimensions that can be achieved by 3D printing?
It depends on the equipment used; here are several options on the market. Sizes range from a few millimeters, to typically several centimeters. For laser printing, normally an envelope of 400x400x400 mm is used but larger equipment is available.
What minimum cell size is possible to print for open cell like structures?
If you are referring to the smallest lattice structure that is possible to attain, it depends on the AM technology, machine, material, developed parameters, component design, customer criteria, printing parameters, and the empty space needed to allow for the loose powder to escape. To state an example, it’s not uncommon to print lattice structures with empty spaces measuring a few tenths of a millimeter.
How about the gas used for the 3D printing operations?
Normally argon or nitrogen is used in powder bed fusion laser, as the protective atmosphere.
What about laser power and laser types regarding process using it (SLM, LMD, LMWD, LMPD)?
Typically laser power is maximum 400 W, but this is modified as a part of the print parameter settings used, where scan speed, hatch distance and laser power are some of the parameters settings. Yb-fiber lasers are common in additive manufacturing but in some applications such as printing Copper, other laser sources may have to be used.
Where should we use these kind of powder additives in the field of mining?
There are plenty of parameters to consider when finding an application that can be motivated to manufacture additively. We have gathered some information on the matter on our website, and in addition, you are always welcome to get in touch with us directly for support and advice when it comes to implementing AM into your offering.
What are the risks that we have to consider when working with metal powder in AM?
The most prominent risk when working with titanium powders is the risk for explosion, due to the materials’ inherent reactivity.
Does Sandvik currently recycle their inert gas used in atomizing and 3D printing?
Not as of today – but we are however looking into various solutions allowing for us to do so, within the near future.
Can these additive materials be used on HP 3D printing machines? Or, do you recommend any other manufacturing company?
Yes, several of our powders can be used on a HP machine. We manufacture and tailor our metal powders according to your specific needs and specification. Materials such as Titanium and Aluminum are generally more difficult to print using Binder Jetting Technology, but there are some of the providers of the technology that have the ability to print Titanium.
Are there any plans of diversifying into 3D printing of Tungsten Carbide components?
Yes. As a matter of fact, we are currently developing additive manufacturing processes for cemented carbide. Please send us an enquiry if you are interested in learning more.
Are you interested in cooperation on powder testing using SLM and SLS processes?
We are always open for interesting suggestions and cooperation’s regarding material development. Please get in touch and we'll be happy to discuss.
Can we print with gold instead of steel?
It is possible, but for known reasons very expensive.
Are you manufacturing in India?
The AM division does not currently manufacture anything in India. Other parts of Sandvik, however, do.
I’m interested in applications of Hafnium through Additive Manufacturing.
Hafnium is used mostly as an alloying element for controlling microstructure and materials properties. We have no experience of printing in Hafnium alloys or pure Hafnium.
How you see the future in terms of utilizing quantum computers?
This is an interesting question. Of course, artificial intelligence will support our future development, and we except quantum computers and similar digital support to be part of this. To which extent, however, remains to be seen.
