WASP presents own method of creating personalized 3D masks against COVID-19 pandemic

WASP is known mainly for the production of large-scale 3D printers based on the delta system. Their most popular project is a modular system for 3D printing houses, i.e. a nearly 12-meter structure, allowing for spatial production of concrete.

In the face of this situation, the company changed its area of interest and focused on methods to prevent the intense expansion of the virus. The WASP research and development department suspended the work carried out so far and started the implementation of two projects – MY FACE MASK and MY SPACE. Personal protective equipment created as part of projects is intended to reduce the risk of contracting SARS-CoV-2.

MY FACE MASK

The assumption of the MY FACE MASK project is to create a mask ideally suited to the shape of the user’s face, which will protect against contact with the virus. The virtual model is created by photogrammetry – based on the collected data, you can model the mask (a simple scan can be done even with a mobile phone). Below is a video shared by WASP with detailed instructions on how to create a mask based on a 3D scan in the free Blender program.

WASP printed its masks from PCL, a biomaterial that can successfully stay in contact with the skin. They made use of the Delta WASP 4070 3D printer. The 3D printing time of one mask is about four hours.

The mask can be subjected to repeated disinfection. For its proper operation you need a standard filter that can be replaced. Personalizing the shape of the mask not only provides better protection but also higher comfort of use – it prevents, among others abrasions with prolonged wear.

Detailed information on how to make a mask can be found on the WASP website or in the forum thread dedicated to the project.

MY SPACE

The second project is MYSPACE – creating transparent “helmets” that give the possibility of breathing air without viruses and without limiting visibility. The air inside the helmet is filtered and forced in by a battery-powered fan.

The cover protects not only the mouth and nose, but also the eyes and ears. It also does not limit the sound – small holes at ear height do not limit audibility.

Currently, WASP has created five “helmets”. They do not yet have any type of certificates – the company is at the stage of searching for strengths and weaknesses of the solution. The company’s goal is to enable medical staff to transfer equipment safely and quickly.
