DNA Extruder | Fastest, Precision at Home Filament Extruder
Fastest consumer level extruder on the market. High quality & precision filament, thanks to a new & innovative approach to the process.
The 3D printing community is growing and innovating each day. Printers are becoming better and better, with higher print speeds, new features and capabilities. It is now time for the 3D printers' counterpart, the filament extruder, to join the race.
Introducing the DNA Extruder, a never-before-seen combination of speed, precision, quality and aesthetics. An entirely new approach to the filament extrusion process.
DNA is a new and innovative filament extruder created by Protea Design. Meticulously engineered, DNA is aiming to bring a new meaning to dependable high-speed extrusion. Our goal was to create an extruder which has features and performance of a machine double its price. After nearly 3 years of development we were able to create something that is compact, fast, tough, lightweight, affordable and easy to use. The DNA Extruder will be the last filament extruder you will ever want to own.
During development of DNA we paid special attention to solving the issue of slow extrusion that many extruders available on the market face. With the use of our patent pending screw and barrel design we were able to increase extrusion speed to levels never before seen in an extruder priced below $1,000 or even $2,000. The DNA Extruder is capable of extruding filament at a rate of 10 feet per minute, which amounts to 1 full roll of filament in 1 hour. These speeds were easily reached even while extruding ABS materials, which is a much tougher material to extrude than PLA. With the extrusion speeds provided by the DNA Extruder you will never have to wait more than 1 hour to get back to 3D printing with a full roll of filament.
To keep up with the extrusion speed of the machine, we equipped the extruder with a hopper large enough to hold roughly 1kg of pellets when fully loaded. With a fully loaded hopper you will be able to extrude an entire roll of filament in one go. Just load the hopper and have a brand new roll of filament in an hour. No more waiting around and feeding the machine, or being restricted by a small hopper.
Specifically for this project we designed a new and innovative thermoplastic extrusion screw and barrel combo, which allowed us to reduce the overall size of the machine and provides users with a machine capable of extruding a higher quality filament. The use of this specific thermoplastic extrusion screw helps to promote higher pumping pressure for extraction of water vapor and air from the filament, and improves mechanical operation through a direct connection to the motor. All of this amounts to a much higher quality and consistency of filament being extruded. Each extrusion screw is individually machined out of a block of steel and tested by a professional before it is delivered to us for further testing and installation.
The DNA Extruder is ready to go in minutes. Equipped with a 600W internationally compatible power supply, DNA allows you to easily switch between 110V and 220V whenever the situation requires. What's even better, there are no special plugs or cables needed to get the extruder going. We decided to make things as simple as possible by giving you the ability to use the same power cable you use for your PC. This allowed us to reduce costs and simplify everyone's lives just a little more.
Continuing with our focus on simplification, we made DNA very easy to operate. The temperature is adjustable up to 250C with the use of a digital PID temperature control unit. Speed is also user specified and can be adjusted with a simple twist of the wrist. There are separate switches for the extruder, the heatband and the motor.
The DNA Extruder is ready to go in minutes. Just don't forget to let the machine warm-up.
The enclosure is a one-piece unibody design made from a lightweight, high tensile strength, and heat resistant polyurethane material, bringing the extruder’s final weight to a total of 4.7kg when fully assembled. The unibody design gave us the ability to reduce weight by excluding extra materials that would be used to connect multiple pieces together. This design also provides increased rigidity and toughness to the enclosure. We further strengthened the enclosure by designing mounting points for mechanical components in areas which appeared to need reinforcement. Each shell is individually checked for any structural weaknesses or defects before assembly begins.
One of our biggest focuses when designing the DNA Extruder was to reduce the final price and increase availability of replacement parts. This lead us to using easily found components rather than custom components. Watch the video below to find out more about what we use.
There is a simple reason for choosing to extrude your own filament. It's much cheaper. And with the use of the DNA Extruder, the costs just keep falling. The efficiency that is offered by DNA will have you getting a return on your investment in no time. Whether you decide to make filament for your own 3D Printing needs or for sale to others, there is no better choice than DNA.

Risks and challenges
Just like with any new product, there are always risks and challenges. However, it is our mission at Protea Design to anticipate and mitigate any that may arise. Unlike many KickStarter projects, we have finalized our prototype and found manufacturers and suppliers for each component way before starting our campaign. Furthermore, we have already received a production sample of each component and have tested everything for durability and high quality that we at Protea Design are requiring each of our suppliers to provide. We wanted to be confident that we could meet any demand that might be generated and avoid delays or faulty components. Each of our suppliers have passed the quality and timeliness test, reinforcing our confidence in this campaign. Nonetheless, there is always a chance that something can go wrong on the supplier side, no matter how much you prepare. Therefore, we have backup suppliers for our components and stand behind our promise to deliver a quality product to each and every one of our backers without fail. If for any reason there are delays or any issues do happen to arise, we will make sure to update everyone on the situation and what is being done to resolve it.Learn about accountability on Kickstarter
