3D PRINTING WITH TITANIUM - Makenica 3d printing services

What is Titanium?

Titanium is a lightweight metal and has mechanically strong properties. It is biocompatible and resists corrosion very well.

Because of these properties it is a favorable material to be used in high-tech fields like aeronautics, space exploration and the medical field.

What are the advantages of titanium?

• Prints complex shapes that would not otherwise be feasible
• Prints complex designs
• Prints wireframe geometries
• Has non-demountable mechanism
• Helps in speed reduction
• Helps in assembly time reduction
• Helps in weight reduction
• Helps in mass customization
• Allows Remote production
• High tensile strength
• light weight
• extraordinary corrosion resistance
• extreme temperature tolerance
• Increases possibilities in terms of design
• Increased flexibility

What are the disadvantages of titanium?

• Titanium is an expensive metal
• Printed part can become quite distorted because of the high temperature that’s applied during printing.

What are the applications of titanium?

• Used in DMLS (Direct Metal Laser Sintering)
• Used in EBM (Electron Beam Melting)
• Used in DMD (Direct Metal Deposition)
• Used in SLM (Selective Laser Melting)
• used for implants

Which technologies are used to 3D print with titanium material?

·     Direct Energy Deposition

A high-intensity energy source as a beam is used to melt the titanium powder and is deposited through a nozzle onto the substrate.

The key benefit here is the ability to print large parts at a comparatively high material deposition rate (up to 320 cc/h).

·     Electron Beam Melting

In EBM, an electron beam is applied to a layer of metal powder, melting and fusing it with the previous layer.

EBM is considered to be more accurate than DED, and suitable for smaller, complex parts. Notably, the EBM process takes place in a vacuum and at a high temperature.

This results in minimal residual stresses in 3D-printed parts, which also means the parts don’t require subsequent heat treatment.  
 

·     Selective Laser Melting

This is a powder bed fusion process, although it uses a laser beam instead of an electron beam to melt and fuse the layers of metal powder.

The thickness of one layer in the SLM process can be as thin as 20 microns, which makes it more accurate when compared to DED and EBM.
 

How does the DMLS 3D printer work with titanium?

• DMLS (Direct Metal Laser Sintering) is an additive manufacturing method. This technique prints parts additively by sintering fine metal powder particles, to combine them together locally.
• The printed metal part will be created layer by layer, according to the 3D model designed.
• The sintering temperature is 1510°C compared to 160°C to 200°C for polyamide
• DMLS has many advantages-
• building extremely complex geometries
• including free-form surfaces
• deep groves
• cooling channels within injection moulding tooling
• reduces turnaround time
