Circular Design for additive manufacturing - Designing Lithium Speaker in Fusion

Hi, and welcome to this episode one, designing the lithium speaker in out-risk

So, first episode, and this is what we're going to talk about, how to build a

circular design with additive manufacturing, what higher digital product

of course everything what we do is also in mind for how to repair this one, how

it, repair it, and one day maybe even recycle it.

So, this would be the first episode of Focus Today is to go through out-risk

I will show you a little bit how we are designing for additive manufacturing.

So we are in out-risk fusion, this is the complete assembly you're looking at

speaker lithium 2, lithium 2 is when it has a carbon fiber driver, it's a high-

quality speaker at the moment, it's a passive element, it can be equipped in

with inside electronics more than a passive crossover, but at the moment it's

for either, you know, smaller kind of shelf speakers or as a part of the Dolby

So yeah, so what if this high-end sound could start with recycled material, and

That was the whole kind of vision we had for Infinite, and that's what I'm

in this series, but let's first have a look at the inside of the speaker.

So one thing what was super important was to have a consistency in where the

product passport was aimed and where it was placed.

And obviously you want to place it in a place where the user and the consumers

So in this cut you see that it's placed inside the actual dome on the top dome,

and it's always beneath the actual logo, so it's always beneath the logo system

But of course there's no way you can get to this without tapping it with your

and that's the whole intention, that you shouldn't be able to peel off an

a data carrier so easy, and it should be part of the whole life cycle and the

So yeah, let's go in a little bit deeper, and I wanted to show you also how we

designed lithium and how this kind of atomic style came about.

We are now in the beginning of the design, so in out of this fusion your whole

history is saved, and that's a pretty amazing thing.

You can always go back in your history and see what you have done.

So the whole concept for infinite acoustic works was to build the world's most

hi-fi speaker, one that can be made locally in micro factories, in 3D print

recycled materials, using, of course, hybrid materials like Adnite, which is

built for acoustics, because it also contains EPDM rubber.

We will talk about that later on in the series, how we designed and developed

So when we started the design, we knew that we had acoustically very, very good

We wanted to build something which could be branded in a cool way, but at the

thinking about how music and waves around, they are not cubical, which most

look pretty awful as they are based on MDF boards or different type of wood

where you have that element that you have to follow.

So this was the round kind of atomic design that is its basic style and form

and that was done with an organic form shape tool in fusion, which is very,

where you can organically shape whatever you want to have.

So we fell for the shape, which was also important as we knew the limitations

So most 3D printers, depending on which type, in this case we wanted to use FDM

Modeling Printers, which is the most common 3D printers, we need one flat

We don't want to build something which have an incredible amount of support and

to build, so we needed to have something where we could basically build a home

for a Twitter or for a woofer, where it would be very complacent and fit very

These prints you can imagine are on a subwoofer, not lithium, it's up to 100

you also have to look at the machines, have to be able to do this without

So there is some openings here, all the holes, these are actually connection

a speaker most of the time is not one element, it's minimum two elements, very

in the line arrays we build, you have to five or six elements.
