Hi, I ordered the same book the day before.
I hope there are some good inspirations in it or in the other book I ordered.
I don´t think I´ll get the time to tinker with injection molding in the next few weeks but the wintertime is long and I have a lathe 😉

Greetings from Saarland

Sounds good,
I think this could be a good addon. Maybe it is possible to combine the shop press with the injection molding machine…
I´ll take some thoughts about this 😉

Thanks,
yes it is a lot of fun to work with. Today I presented the Setup in Neunkirchen, a city next to my location. I carried it to the market place, built it up and started my presentation. I got a lot of good response for this workbench , the idea behind it and my products.
I met a lot of interested people and I think that this is a really good start for this project. I made contact to 2 schools and I think I can present the workbench there too.
Maybe it is possible to start some cool projects wit their pupils.

Hi, I used this motor.

https://www.ebay.de/itm/Arebos-Elektrische-Seilwinde-Motorwinde-Hub-Seilhebezug-Seilzug-Winde-Kran-NEU/112536907073?hash=item1a33b8ed41:m:mZJDgG-v8ry30fYVRLo1QmQ

This winch motor is so powerful that it bent my Shredder axis coupling when I tried to shred 6mm thick PMMA plates 🙁
The spool from the powerful 1800W (500/1000kg Version) motor is stacked on to an 27mm hex bar. you can easily pull it off.

Thank you very much.
I recently tried some different things, like a stool, a clock and a planner.

A few weeks ago I saw a Video on YT in which some resin castings are made.
They used a blowtorch to pop all bubbles on the surface after casting.
I tried the same after I melted the printed parts, just before I pressed it into the mold.
With success. All bubbles popped and I got a smooth surface.
After a little bit of cooling I filled the inner Bowl with boiling hot water to slow down the cooling process, because last time I got some small cracks on the surface.
I hope it will work.
I am very excited and I can´t wait to see how it comes out of the mold.

Yes, I saw this video. For this reason I wanted to built the same Shredder.
I ordered the same motor and I hope that is enough power for crushing the 3D printed parts.

Nope. I ordered the Parts for the 27mm hex bar version.
I hope that it will work with the slow 1,5KW 30rpm motor I ordered.
Otherwise I´ll sell it on eBay and built the stronger one 🙂
I´ll give s2019´s idea with the shop press crushing a try tomorrow.

Thanks you for these tips.
I hope that my laser parts for the shredder arrive this week, so that I can granulate the parts and then dry it before melting.
I think most of the air bubbles come from the infill pattern in the printed parts.
maybe it is a good solution to heat up the printed parts to around 50 degrees Celsius for an hour or so to dry them before raising the temperature up to the melting point.
