| Résumé : |
Continuing miniaturisation of many products requires a method of dispensing very small amounts of liquids. Inkjet technology is capable of applying adhesives and many other functional liquids as well as inks with great precision. Its versatility and potential in industrial applications is illustrated by the example of coating a drug-eluting stent with a polymer/drug formulation. |
| Note de contenu : |
- Optical fibre systems require precision bonding
- Practical issues can be complex and varied
- Stent coating provides efficient drug delivery
- Flexibility of stent poses practical problems
- Real-time computer control is essential
- FIGURES : 1. Bonding process in a laser coupling device for optical fibre systems : overview of laser coupling device ; (b+c) adhesive dispensing with macroscopic droplets ; (d) smaller droplets improve the dispensing process - 2. Drop generation and impact during inkjet dispensing process are influenced by material properties and other effects - 3. Drug diluting stent ; only the outer surface needs to be coated (see enlarged view) - 4. Design of the stent coating process - 5. Stent coating in progress showing inkjet dispenser and rotating mandrel (left) with a close-up view in which the inkjet droplets on the stent are dyed to assist in visualisation (right) |
