V4 Product Design – Furniture

21/05/2019 at 11:08

Hey people!
We are now embarking on the Product Design phase of the project. There are several ‘topics’ we are tackling and this one will be focused on Furniture design. We will share our thinking along the way and are open to your ideas and suggestions.

@v-varella has created a topic about Product Development in which he speaks of the core “values” that Precious Plastic products should hold. We should strive for Precious Products to:
1. Change the perception of recycled plastic to a valuable and versatile resource.
2. Engage with new audiences by building excitement around the material.
3. Produce with techniques that encourage local high quality output.
4. Embrace the unique qualities of the material.
5. Share accessible tools that enable the community to overcome challenges.
6. Explore the world of possibilities that the machines can offer.
7. Commit to circular economy principles and not contribute to other problems in the long term.

Some references from furniture I have been looking at…

This is a variation of the previous bench, with a different lower part (easier to cut)
+ an exploded view of both models.

great stuff, with a few angle side brackets (from recycled aluminium 🙂 to enforce the angles you have a solid product 🙂

Going modular is indeed a great concept.

Just provide the basic building blocks and ‘a table’ can adjust to the ever changing taste of its owners.

@pporg , sounds like a great project. Looking forward to your results. When @timslab showed his tube rolling results I wondered how hard it would be to introduce a reinforcing fiber (tape). Sort of an in-situ resin transfer or prepreg process.
Good luck

Yes, a freelance designer should always have a plan for managing their designs and other intellectual property. It may be easier to do with an engineered CAD file for a product mold than for a sketch of a chair. I think this forum and PP are promoting an open source environment but I’m not sure there are any restrictions about advertising custom design services in the Bazar.

It was suggested I link this topic on Plastic Gridbeam here in case it might be of interest. Thanks.

@donald , Thanks for the link…Just what I needed, another hobby rabbit hole to investigate. I did find it interesting how he picks the PVC for toughness in this video (1:45) https://www.youtube.com/watch?v=lTkNNbZk5Ms . I always thought of PVC as brittle, this may open up some options in addition to the obvious Zombie prep. Also the use of dry wall as hotbox liner is interesting. The actual specs are confusing. For example the fire rated drywall get a 3-4 hour fire rating but the manufacturer states to avoid prolonged exposure above 52 C.

Thanks for the reference @donald

For the upcoming week I’m going to research more in the process and see what can we learn from already used processes. Glass slumping, wood bending, plastic forming and all sort of different processes that might share some similarities in order to have a broader perspective of it.

I’ll keep updating!

Might seem off topic, but this reminds me a lot of techniques used to build PVC bows.

This guy has done a lot of pioneering on the subject.

So I don’t know about this specific technique, but plasticsmithing can also be used on other plastics. And yes, it is strong. The drawweights of the bows you can build this way are more than sufficient to survive any Zombie Apocalypse!

The Etsy summary is good – but I notice it skirts around details of the Design Patent (known as a Registered Design in other countries).

In the EU there is also Unregistrered Community Designprotection – which is shorter, but doesn’t involve the same cost as a Registered Design.

None of them are much use if you haven’t got the money to take any infringers to court. 😉

Copyright law is effectively Global, through treaties, just not enforced the same everywhere…


Furniture (or indeed any utensil) are indeed harder to grasp than e.g. literature or ‘art’.

The difference is however in the ‘design’.

Is it just meant to be functional, it’s an invention (a device to levitate thyne arse off the floor).
If it is however primarily aesthetic, not just functional, it is design, and as such copyright. An aesthetic variation on the invented utensil. You’d have the copyright over the variation, even though you might not have invented it.


Think Lego: they patented the blocks they invented. Patent expired after 20/30 years, oh sh*t.

Their little ‘man’ they however copyrighted. A lego brickhead is not just technical, it is also aesthetic (designed): copyrighted until XX years after the death of the creator.

Noticed how they are now marketing there ‘brickheads’ instead of bricks?

How a chinese factory got closed because of pirating starwars-lego, not the lego in itself?

Hello @donald
Open source products is a hot topic and there is much to be discussed when it comes to how to make profit.
I believe that designers should earn something from each sell as they have made that possible in a way. However important it is this is not something we are referring here.
We shared this values in order to show what we stand for when designing for V4. Enable workspace to make profit is one of our clear focuses since we’ve seen people struggling with this, (long and slow processes, expensive collection system, not always the best output, lack of functionality…) This are problems that can be addressed from the designers point of view when a product has to be design. (Using the right amount of plastic, processes that are accessible yet gives a nice output, consistency through repetition and dividing production by stages to agilize the process…) This are all design considerations that will help enabling somebody who repeats the design make better profit on their products.
Having said that, this values are not ment to be a call for designers to give their designs for free. This is just to show what we stand for when designing products here in Eindhoven. If we ever make a platform such as open desk in which people can upload their designs, get tested and then accepted in our catalogues to produce wherever there is a PP machine then we can talk about designers rights. But that’s Butn the case now, maybe in the future. For now we are a bunch of designers contributing to V4 and that means that the same way we have engineers making a sheetpress we as a designers will make products as part of our contribution.
I hope this clarifies a bit what we ment by that even though I haven’t dig much into the open source topic. Thanks for sharing your comments.

I’m sorry, but you’re wrong.
This topic is a call for designers outside V4 to share.
And  more importantly @timslab has already answered my question.

He asked for more designer input. I asked my designer friends and contacts to help, but they ALL replied with “why are workshops allowed to make money, but we are not?”.
well, you need free designs to bundle with the machines. Fine. I can’t help with this.

what’s the problem?
