Differences Between Aerosol-Jet 3D Printing and Traditional Inkjet Printing


Function

Aerosol Jet Printing

Inkjet printing

Advantages of Aerosol Jet Printing

Minimum resolution capability

<10μm

~30μm

Finer feature sizes

Single-layer thickness

25 nm–10 μm*

~0.1–0.3 μm

Improving Process Control

Material viscosity

Above 0.7–2,500 cP (up to 10,000 cP under laboratory conditions)

Approximately 5 to 12 cP (depending on surface tension)

Broader material selection and deposition thickness control

Solid content

Approximately 70 wt% or more

<50 wt%

The higher the metal or ceramic content, the less solvent and the more material.

Material formulation development time

Heaven and Moon

year

Existing and new materials can be developed and used very easily.

Functionally Graded Materials

Yes

No

Can be used for functionally graded materials.

Pattern Generation

Numbers in CAD: Direct Vector

Digital grating

More precise

Printhead Position

Pitch between lenses: 1–5 mm; focal length approximately 2 mm.

The print head is fixed approximately 0.2–1 mm above the substrate.

Conformal deposition printing can be achieved on irregularly shaped substrates, as well as for narrow, grooved channels.

3D direct writing

3-axis, optional 5-axis

2 axes, with the Z-axis operated manually.

Three-dimensional ability
