As all door handles have different diameters, do contact us with the specific measurements if you are interested in getting it for the office/home. We will try our best to customize and cater to your specific requirements.
The SituationAs the COVID-19 coronavirus continues to impact our daily routines, our applications team has been hard at work working on a few designs to help the healthcare community.
No matter where we go to, we are faced with door handles, and they are hotspots for germs because of their often and inevitable usage. Our additive manufacturing solutions partner, Materialise, was one of the first to answer the call of the community by releasing design files for a hands-free door opener to help stem the spread of the COVID-19 virus.
But there is no one-size-fits-all solution and so our application engineers set about designing a hands-free door opener that fitted our office doors in particular which had fixed stainless steel handles with no assembly required.
The power of 3D printing enabled our application engineers to customize a hands-free door opener exactly to requirements. Our team set about designing the door-opener as simple as possible and can be printed as a single piece, with no assembly required nor any post-processing. Just print, dissolve support material, pat it clean, and mount it on the door handle.
For this particular design, we used ABS material and printed using a Stratasys F370 FDM 3D printer. ABS was chosen for its toughness and strength properties, allowing it to withstand heavy and repeated usage.
As one of the most basic engineering materials that are lightweight, affordable and readily available, good designing can bring you far since ABS can be easily molded to create the desired form.
- Patented heated chamber – prevent warping
- Dissolvable support material – easy post processing
- Toolpath optimization – design optimization
The above mentioned three factors are important because others can’t quite achieve that same performance.
Although there are other high performance materials such as PC-ABS or Nylon 12CF which can achieve more rigidity, it will be an overkill for this type of application in terms of material costs, where ABS would do just fine.
* The door openers are not immune to contamination, so regular disinfection is recommended.
Taking into account the usability feedback from our initial version, our application engineers went back to the drawing board and came out with another design where we fasten two 3D-printed pieces together with screws over an existing handle.
This time instead of ABS, we opted to use PC (polycarbonate) material for its toughness and stability properties, allowing it to withstand heavy and repeated usage in the long run.
