Walker Prototype

3D printing used for a good cause.

Using ZMorph 2.0 SX I was able to materialize and prove my idea for a multifunctional walker that could help disabled people in performing everyday tasks.

Activity as simple as walking becomes a challenge when someone struggles with old age or limb disabilities, especially as there are not enough inexpensive medical solutions that could help them. Designer and biomedical engineer, Eliza Wrobel, decided to improve the widely popular walker design and make it more functional, in order to help those, who want to stay active despite their disability. She used ZMorph 2.0 SX multitool 3D printer to materialize her idea in a form of a convincing showcase model.


The multifunctional walker features switchable add-ons (shopping cart and a baby seat) and retains the basic functionalities of a walker, including regulated height. Built from 3D printed elements, handmade cushion, wire, straps, and screws, the prototype consist of over 100 parts. Silver ABS was used for the frame because it made it easy to clean off the support from the tubing, while yellow and black PLA parts proved to be more durable. Black rubber-like Flex filament was also used for wheels, brakes, and arm pads at the top.


The prototype was built in a 1:2 scale to prove the idea, so one day it can go into mass production. Serving as a proof of concept and a showcase model, it can be used during design meetings, business and investor meetings, and even trade shows. It’s also a fine example of how 3D printing can be used to reinvent and innovate in product development. Relatively low costs and short production time give an additional advantage, especially to young creative minds wanting to help the ones in need.
