The Problem of Hygiene at Contact Points
Door handles and push buttons are among the points with the highest bacterial load in any building. Each hand that passes leaves a trace that, after a few hours, can become a true ecosystem of germs.
The antibacterial effectiveness of this filament has been tested and certified by an external laboratory under ISO 22196 standard. The test was performed on two bacterial strains: Staphylococcus aureus and Escherichia coli. The results obtained indicate a reduction in bacterial activity of 99.99% after 24 hours.
Why Choose 3D Printed Handles with Antibacterial Effect?
| Problem | Solution |
|---|---|
| Rapid accumulation of bacteria, bad odors and stains | The active silver present throughout the material destroys the bacterial membrane and maintains the surface hygienic for 24 hours. |
| Cold or uncomfortable metal parts | Antibacterial PLA offers a pleasant touch and can be ergonomically adapted to any hand. |
| Need for urgent replacements | 3D printing without tooling: we manufacture and ship complete handle sets in days. |
| Design changes due to renovations or accessibility | We adjust the digital model (shape, size and anchoring) without cost of new molds. |
Where They Make a Difference
- Hospitals and health centers: consultation doors, restrooms and waiting rooms.
- Schools and daycares: classrooms, bathrooms and common areas with high child traffic.
- Offices and coworkings: offices, meeting rooms and main entrances.
- Sports facilities and gyms: locker rooms, lockers and court access.
- Public buildings: libraries, town halls, administrative service centers.
And Not Just Handles…
The same antibacterial material is ideal for other rigid high-contact accessories, for example:
- "Hands-free" push buttons for light switches or doorbells.
- Drawer and cabinet pulls.
- Hand sanitizer dispenser supports.
- Elevator buttons and push plates.
If your project requires a clean and resistant surface that is disinfected daily, this filament is a safe bet.
What Makes Our Material Special
- Premium PLA + silver: prints with the same ease as standard PLA.
- Permanent antibacterial effect: silver is distributed throughout the piece; each layer protects.
- Sterilizable without problem: resists UV-C light, ozone, EthOx or diluted bleach.
- Natural or white color: we do not recommend painting or varnishing the piece; a coating would cloud the active silver surface and reduce antibacterial protection.
Three Design Guidelines for a Cleaner and More Durable Handle
- Eliminate deep corners where dirt can accumulate.
- Round edges (radius ≥ 0.5 mm) and borders to facilitate quick cleaning.
- Avoid continuous temperatures above 55°C (PLA could soften).
