Node-Audio Achieves Unprecedented Audio Design with 3D Printed Audio system

In 2019, a British startup unveiled aesthetically revolutionary high-end home loudspeakers prototyped and produced utilizing 3D Techniques’ selective laser sintering (SLS) and DuraForm GF materials. The luxurious and tech-forward geometry of the HYLIXA speaker by Node-Audio (Node) guarantees a “innovative” expertise that gives excessive sound high quality in a package deal that doesn’t dominate a room, in keeping with HiFi music consultants. For 3D Techniques, the distinctive and sophisticated cupboard construction of the product represents a real departure and HiFi business breakthrough, made potential by utilizing SLS know-how.

Node is the imaginative and prescient of two British industrial designers, Ashley Might and David Evans. Impressed by the capabilities of additive manufacturing, they got down to ship merchandise that convey the emotional energy of reside music into the customers’ residence.  Primarily based in Cambridge, UK, the non secular residence of British HiFi, Node is a hub for audio analysis and innovation, claiming to problem the present state-of-the-art within the pursuit of absolute musical purity. Node’s founders Might and Evans contemplate their product as gorgeous acoustic sculptures that convey distinctly human really feel that will also be thought-about an funding in emotional enjoyment for years. However most of all, they imagine in profiting from the additive course of to plan a high-value, high-performance product that’s distinctive in a worldwide HiFi system market that’s anticipated to extend 28% within the subsequent 5 years, as per a report by Analysis & Markets.

With entry to a 3D Techniques SLS 3D printer of their manufacturing facility known as Studio17 Design, on the ARCC Campus amidst the Cambridgeshire countryside, the duo got down to reconnect folks with a brand new breed of HiFi system. Removed from the standard monolithic archetypical speaker packing containers mounted inside an enclosure that had largely disappeared within the early 2000s, the HYLIXA loudspeaker produces audio high quality that the creators say rivals a reside expertise, with lovely, sculptural aesthetics, because of 3D printing processes.

“It was like a recent begin for us as designers,” stated Evans. “We’ve all the time recognized design issues so that they might be manufactured in a selected manner, whereas this kind of threw all the pieces out the window and opened up our imaginations to what was potential.”

3D Techniques reported that the event course of started with 3D designs from Evans and Might that then ran via specialised 3D audio simulation software program to tell the subsequent iteration. Afterward, because the simulation output started to verify the next-level sound the crew was after, they started to prototype and refine additional, till lastly arriving at Node’s flagship product, HYLIXA.

Manufacturing and prototyping for the HYLIXA audio system are accomplished utilizing the 3D Techniques sPro 60 SLS printer, with every of the 2 audio system within the set printed individually inside the printer’s 381x330x460 mm construct quantity. Evans defined the crew maximizes every construct by nesting the opposite parts inside the speaker cupboard in order that the cupboard and entrance baffle parts are printed as a single unified half in DuraForm GF, a glass-filled engineering plastic that delivers a floor end that’s machinable and paintable and takes 45 hours to make. As the first show piece of the audio system, Node places the HYLIXA cupboards via a methodical post-processing routine to take away the un-sintered powder, and put together the surfaces for no matter ending the shopper requests.

“We discovered via the prototyping course of that DuraForm GF really labored very nicely acoustically. It has nearly a ceramic-like high quality to the contact, which helped us each structurally and sonically. As designers, we might freely exploit SLS manufacturing to create the inner construction, but in addition design one thing that appeared as lovely because it sounds,” indicated Evans. “Each element that we 3D printed, we’ve accomplished for a motive. We’ve used the know-how to profit the product in a technique or one other, and pushed to take all the pieces to absolutely the restrict.”

By leveraging the laser sintering method Evans and Might declare to have devised the world’s first ‘helical bass’ enclosure. This inner helix acts as a waveguide to boost bass efficiency, with out compromising the acoustics in different areas. The patent-pending helical transmission line spirals for 1.6 meters round a conical cupboard inside. This line is fed by a devoted bass driver and releases the sound via a round vent across the mid and the tweeter. As a result of the rounded cupboard is designed and manufactured as a single piece, there aren’t any edges to provide diffraction (a disruption to sound precision).

At £30,000 (roughly $39,000) per set, the HYLIXA has a aggressive edge because of 3D printing, embodying the type of luxurious that loudspeaker clients anticipate, from lovely designs to excessive sound high quality. However most of all, the SLS know-how permits the designers to create complicated cupboard geometry which might not be potential utilizing extra conventional manufacturing methods. The creators counsel that by replicating the sonic signature of a human head, voices sound startlingly convincing, “as if the artist was within the room.” Furthermore, opinions on many HiFi music gear websites have acknowledged HYLIXA as an aesthetically distinctive compact system and sonic deal with.

For now, the product may be skilled at a number of British areas and in Tokyo, Japan, however after having earned credibility inside the business, Node-Audio is seeking to develop. A part of the growth entails new plans that are “very prime secret” in the intervening time, however one factor is for positive, the designers stay dedicated to utilizing 3D printing processes as an integral a part of the corporate’s technique to differentiate itself and do issues which have by no means been accomplished earlier than.
