1. Why is glass a material which is congenial for the fabrication of medical medical microdevices?
Glass provides biocompatibility, chemical resistance, and low MRI footprint, for medical-grade components.
2. Is glass’s brittleness a limiting factor?
Glass is scarcely a limiting factor when the device is highly miniaturized as it is the case with implantables which be also specially coated for additional protection.
3. Is FEMTOPRINT’s production of glass devices ISO 13485 compliant?
Yes, glass microfabrication can meet ISO 13485 standards for medical device manufacturing.
4. Can glass be bonded with other materials
Yes, glass can for instance be bonded with silicon, a material of choice for electronics’ deposition
5. Can glass be used for implantable microsystems?
Yes, it is inert, non-toxic, and highly biocompatible.
6. Is glass microfabrication suitable for sensors and MEMS?
Femtosecond laser machining allows integration of cavities, vias, and channels for sensor packaging.
7. What level of surface roughness / smoothness can be expected on devices generated by FEMTOPRINT?
A variety of post processing treatments complementing FEMTOPRINT’s micromanufacturing guarantee low roughness levels.
8. What bonding techniques are used in MedTech glass devices?
Thermal fusion, anodic bonding, and laser bonding ensure biocompatible seals.
9. Can glass components be metallized for connectivity and increase functionality?
Yes, metal coatings and electrodes can be integrated for signal routing or sensing.
10. Can FEMTOPRINT’s selective laser etching achieve the feature sizes and tolerances my device requires?
FEMTOPRINT’s selective laser allows the realization of extremely complex forms with an elevated degree of precision depending on the design down to the single micron
11. How is micron-accurate positioning of optical, fluidic, or mechanical parts ensured?
FEMTOPRINT’s fabrication eliminates manual alignment, and features can frequently be formed in a single glass block with elevated positional accuracy.
12. Is FEMTOPRINT’s technology suitable only for prototyping?
No, wafer-level fabrication scales efficiently to thousands of units/year, with repeatable quality and predictable cost curves.
