3D printing with Titanium

Titanium spray for 3D printing is an alloy that contains 90% titanium, 6% aluminium, 4% vanadium and other minor elements. The intrinsic properties of titanium combined with the benefits of 3D printing mean that there is huge added value to the use of this technology in sectors such as aerospace and biomedicine.

 

3D Titanium production process

“At Addimen we print with titanium using SLM technology. 3D titanium printers cast this material in layers of 30 to 60 microns based on the power of the laser. Due to the high mechanical properties of titanium, the construction support design phase is especially important so that these can be removed without the part being damaged during the postprocessing phase.”

Titanium technical specifications

Types
  • Ti 6Al4V
Features
  • Low density: 4.4 g/cm3. 01.
  • Tensile strength: 1089 MPa. 02.
  • Excellent biocompatibility 03.
  • Highly resistant to corrosion 04.
Features

It possesses the best mechanical properties per mass unit making it the ideal candidate for light structures with a high-use demand, where the performance of the part prevails over cost. 3D printing uses a lot of the material producing minimal scrappage, this is especially important when it comes to high cost and added value materials such as titanium.

Thermal expansions in the 3D printing of titanium

3D titanium printers create tensions within the manufactured items which must be removed during the heat treatment post processing, especially designed to leave the final product with the intended levels of properties for its final use. If the mechanical and safety demands of the part are very high, such as in the case of aircrafts, high pressure treatments can be applied like Hot Isostatic Pressure (HID)

Step by step process

1
3D File

– Send us your 3D file ready to print.
– If you do not have the file, send us the item and we will create the CAD file.
– If you need a design from zero, our designers will gladly prepare a quote for you.

2
3D Printing

– We will create the process file adapted to the technology and materials that will be used to produce your item.
– We prepare and condition the printer to guarantee optimum quality.

3
Cleaning and post processing

This step is key when meeting your requirements, and it is one that we are highly specialised in.
The removal of the printing support structures, heat treatments, and surface finishes (blasting, polishing, tooling) are some of the most common post processes.

Uses of printing with Titanium

In many cases in which the use of 3D printing with titanium is used, the choice of this technology is justified by the material savings or the benefits offered in terms of design. High performance structures in sectors in which weight is a key variable tend to be the most common market niches. Additionally, the biocompatibility of titanium opens up the possibility of it being used in advanced biomedical applications.
