Here we go!
Maybe we can add here the https://plastic-hub.github.io/noah/ which is nicer for folks to look at 🙂

How about a golf ball which is a Sphericon or an Oloid? Would be interesting for putting and crazy golf.

Dan Shirley replied to the topic Filament maker Beta in the forum Machine development 1 year, 2 months ago
I’d really like to know what is the largest diameter of filament which an extruder like this could possibly make in PET. Could it go to 10mm maybe?
If so, what would be the radius it would bend to ? In other words, how big would the spool need to be?

Hi folks, as usual a far out post about something I don’t know anything about: fume eradication. I just stumbled accross this interesting principle, maybe some smart PPer would like to work with it?

Hi folks, this is not my listing but it’s been on ebay for several months now, out of my price range and would require some expertees… I’d like to think a PPer or PP group could get it working with recycled plastic

Dan Shirley replied to the topic Potential business model for injection moulding in the forum General ideas and suggestions 1 year, 3 months ago
@3dseed That sucks… I’m sure it’s related to the legal side of things, probably also connected with their investors. I looked at those ISO codes at the bottom of that page, the first one is about quality control, but the others relate to medical devices and aerospace parts. That’s the type of thing which requires such high standards.
In that…[Read more]

Dan Shirley replied to the topic Solar Powered Precious Plastic Container? in the forum General ideas and suggestions 1 year, 3 months ago
Solar is definitely the way forward, using muscle-power would be a great addition – but why enslave donkeys or horses when you can charge people for a gym membership?

Dan Shirley started the topic Potential business model for injection moulding in the forum General ideas and suggestions 1 year, 3 months ago
Hi PP’ers,
Lots of people want to do something with recycled plastic, many have the ability to build the machines, and eventually the capability to create injected products.But what to make?
Often the people who are good at the first part – building machines and setting up a workshop-Â are not so interested in designing and marketing products.…[Read more] -

Dan Shirley replied to the topic I need these making for me! in the forum [NEW] Create your own project 1 year, 3 months ago
If you don’t have any machine tools, I suggest http://www.3dhubs.com to have the moulds CNC machined from aluminium. You could use http://www.fiverr.com to find someone to turn the image into a 3D file for the mould, then send that to 3dhubs and they will send you the finished mould. However it might not be cost effective for you do this for such a short run of…[Read more]

Dan Shirley replied to the topic Forum in the forum General ideas and suggestions 1 year, 3 months ago
There is always space for an alternative forum. As happens in many domains of interest, a new forum will likely not detract from existing efforts and may even feed back constructively to PP. I have seen this happen with other forums, and the new sister forum tends to take on a slightly different character can be a good thing. Personally I would…[Read more]

Dan Shirley replied to the topic Cheap and "easy" way to make plastic blocks in the forum General ideas and suggestions 1 year, 3 months ago
Nice! the problem with larger blocks of hdpe is they end up with voids inside. This is due gas bubbles and the only way to get rid of them seems to be to squish the plastic with such enormous force that they compress until invisible. You might be able to reduce their size by adding stiff springs to the bolts so that the plate can move down further…[Read more]

Dan Shirley replied to the topic 3D Printer for PET particles, No filament.. ever in the forum [NEW] Create your own project 1 year, 3 months ago
@occupypp It sounds like you are working on something similar to what I want to do, the PP extruder would make a great hot end for large scale printing. Would the smoothieboard run nema 34s?

The smoothieboard looks like an awesome piece of kit too

Something like this is just what i’m looking for, so an open source design for a PP 3d printer would be amazing!

Dan Shirley replied to the topic Air Fryer in the forum General ideas and suggestions 1 year, 4 months ago
These flat splodges might be a way of making bottle caps and milk bottles easier to turn into flakes without a shredder- I’m going to try planing the edge with an electric planer. It would be great to make small, uniform flakes with just a sandwich press and a planer. Can’t test it now though as its the middle of the night.

Dan Shirley started the topic Combustion engine injector in the forum General ideas and suggestions 1 year, 4 months ago
Another idea which someone may have time and resources to try out before I can:
One of the barriers to building an injector is the problem of having a plunger which fits perfectly inside the barrel. This is difficult to achieve without a lathe. However, a single-piston combustion engine such as a motorbike engine has both a barrel and a plunger…[Read more] - Load More
