Version 4 development index


In this topic Precious Plastic shows a clear index overview of all projects currently in development directly contributing to the Version 4 process.


The Topics are:

Shredder double axis 
Shredder single axis

Sheet press development

Extrusion development

Washing system

Beyond Plastic – bio plastic

New web platform

Also in the process we have:

hey, how’s the shredder going? , seems you need help with that (at least that was said in video) and you asked for volunteers coming to Eindhoven. We started developing a new shredder, dual – axle, gear transmission, may be we can do this via remote as you don’t have the real gear in your workshop (engine lathe, mill). let us know please soon, we intent to offer shredders soon too. thanks and greats, g

@thomasthefirst, Thank you for posting this index. Maybe it can be made a sticky at the top of the page so it is easy to find.

One topic that touches on all of these is testing or how do you know you’ve succeeded. This may be where an outreach to a university may be most helpful. Mechanical test coupons for the materials you generate are simple to make and the tests themselves are standardized and can be compared to acceptable values. If a university could offer to provide the testing (it is not difficult or expensive) then each of these projects would have an objective way to evaluate improvements. This is especially true for the washing project where it may be hard to assess what is clean enough. Similarly techniques for detecting voids in the panels without cutting them up may be useful in developing the press design and process.

We have a Lathe, manual milling and cnc milling machine. For the shredder development please get in contact with Friedrich currently working on this subject.

Thank you for your response. This is totally true and a good approach. We are in contact with the technical Univerity in Delft, but we would really like to get in contact with people specialised in ‘oven building’ , ‘shredder’ expertises etc. Then we can also do feedback sessions through skype. Let us know through the index links!

@thomasthefirst I am happy to hear you have reached out to academia. You have an enthusiastic team developing machines, some of which get involved in fairly complex processes. You also have an enthusiastic army starting to build and use the machines. The safety discussion should be addressed, hopefully task 3.3 (increase safety) can be started up. Unfortunately that task requires specialty planning, engineering, and sophisticated measurements. A technical university is well equipped to address this. They should see the benefit of the PP mission and offer you some resources and consulting. It would be great to have a safety section in the PP manual.

Buenas tardes equipo, encantado de saludaros!!

Estamos formando un grupo organizado en Barcelona para dar fuerza a la nueva version, y así poder fomentar el ideal de esta gran comumidad!
De momento estamos en proceso de crear el equipo, tenemos pocos recursos pero grandes oportunidades e ideas.

Cuando sea posible, nos gustaría saber en que aspectos podemos ayudaros!

Un abrazo enorme!!

@dopy, in case the Eindhoven team still doesn’t accept remote work, you can help us here near Barcelona (San Feliu de Codines) or in our other studio in Tarragona (thermoforming and production), otherwise check here for open remote tasks We currently work independent from the Eindhoven team but we hope all our efforts get emerged sometime into a public pool of knowledge and resources … Most of us in the team speak catalan and spanish, you are welcome to give us a visit 🙂 We always need help with networking, machine building, research, etc…there are some activities to get all the FabLabs on board, with gov. support), plenty of work ..

It would be great if the developers could look into methods of making different sizes of foam padding. It is very useful for making DIY sports equipment. Particularly for gymnastics and martial arts, where all kinds of padding is needed to avoid injury in training. I find commercial products are quite expensive for people who want to set up home gyms. Usually only professional clubs can afford it. I have no idea how difficult it would be to do. Just something to think about.

I’ve found out that the standard method of production is a chemical reaction. I thought it might be a mechanical process (like injecting air into a vat of liquid, or something like that.)
Finding a cost-effective alternative to off-the-shelf products seems unlikely. For small-scale production, at least.Unless someone can invent an entirely different alternative material with the same basic, physical properties.
