The team at Bristol-based OmniDynamics are changing the way everyone uses and looks at plastic, as they have created a way to recycle it into 3D-printer ‘ink’. They have launched a crowd-funding campaign to help them keep up with the customer demand for the Strooder – a machine that turns any recyclable plastic into the material needed to create the 3D printed objects of your desire! Like a bright green Yoda head.

Small enough to fit on your countertop and under £400, it’s very easy to see why the Strooder has gained popularity with first-time tinkerers and fully fledged 3D artists.

David Graves OmniDynamicsIn order for this local startup to grow they are raising money through crowd-funding platform Crowdcube, and are looking for people to invest. TechSPARK caught up with OmniDynamic’s co-founder David Graves to find out more.

From pellets to pencil holders

It makes filament when pelletised raw or recycled plastic is added into the hopper. It pushes the plastic through the machine with an auger screw and is melted along its way. The plastic is finally pushed through a nozzle to form it into a filament.”

Imagine a sausage maker combined with a microwave, put in the chopped up plastic, use the touchscreen panel to select which setting, then it heats up and turns it into a smooth string of sausages ready to be used in a 3D printer. And if that explanation didn’t work for you, you can check out the Strooder in action in this short video:


David tells us working with different plastics is even easier than separating out your recycling, “The speed and temperature can be varied to work with different materials. Strooder comes pre-programmed for PLA and ABS. This means all a user has to do is select their material from the touchscreen and press start.”

“We are always experimenting and hope our community will too.”


Strooder works with lots of different plastic, it works with almost every recyclable plastic so long as it melts below 250 degrees celsius. And for those alchemist-enthusiasts, it also works with elastomers (a flexible plastic material) and some composite materials such as sawdust and plastic to make a wood like filament. David adds, “We are always experimenting and hope our community will too.

“The people that like Strooder the most are makerspaces, schools, hobbyists and now some consumers. We have even had some interest by those in material research.”

You can’t print money

After taking significant orders through its website and having had an initial purchase order from a large retailer, OmniDynamics is raising money to decrease their backlog and reduce delivery time.

“This will result in significant growth, enabling more people to recycle plastic from their home”


David says, “This will result in significant growth, enabling more people to recycle plastic from their home.” After finalising their assembly line and acquiring suppliers, OmniDynamics has now started shipping Strooders to customers. David tells us, “We want to crowdfund to raise additional funds to increase our production capacity to satisfy growing customer demand.”

David also feels the location of the company has helped the company get to where it is today: “The southwest has a great culture which has helped OmniDynamics. It has provided us with networking opportunities and support in multiple forms.”

What’s next for Omnidynamics?

As 3D printing becomes mainstream, and the buzz makes its way into the home, OmniDynamics intends to work on providing settings for as many materials as possible. David reveals, “We are also working on a Strooder-Spooler to wind up the filament onto spools for storage and a Re-Strooder to break up bottles and old 3D prints to be used as pelletised recycled plastic for Strooder.” Making it a one-stop-Strooder-stop.
