Frequently Asked Questions About Drop-On-Demand Technology

Design Guidelines

Design guidelines

What are your key design guidelines?

Our building platform is 48 x 48 x 30 cm. We can readily print digital models that have a bounding box volume of up to 200 cm³. Depending on the complexity of your part, higher volumes may also be possible though. Wall thicknesses and holes generally need to be >1 mm.

Materials

What materials do you use?
We use real silicone elastomers. The performance of the cured parts is comparable to ELASTOSIL® liquid silicone rubber from WACKER.

 

Do you post cure all parts and why?
It is our standard process to post cure parts to minimize volatiles and to maximize mechanical performance.

Condition: 4 hours at 200 °C.

 

What new materials are you developing?
We just introduced ACEO® Imagine GP Shore A 50, we may further expand our hardness range.

How It Works

How does Drop-On-Demand process work?
Silicone material is ejected in the form of droplets (voxels).

The droplets are applied layer-by-layer and the silicone is cured after each layer.

The ACEO® drop-on-demand process allows the printing of complex 3D geometries accurately.

Quality

What about the part quality?
We fulfill the current and local requirements as well as ISO 9001, ISO 14001 and ISO 50001.

The tolerances of our 3D printed parts in the length dimensions are in line with: DIN ISO 2768-1 v. We have a resolution of ~0.4 mm and non-horizontal surfaces will show a layered structure.

Healthcare Certifications

Can ACEO® printed products be used in Healthcare applications?
This is up to customers to determine but our policy does not allow ISO10993 applications beyond classification 2a. Long term implants are class III.

Otherwise, we have the necessary ISO10993 and USP Class VI biocompatibility certificates for compliance up to Class 2a usage for all ACEO® Imagine GP materials.


Can ACEO® technology be used for baby nipple applications?

Not for the moment, we are currently investigating whether we will be able support this application.
