UNSEEN LEGO Star Wars PROTOTYPES & CONCEPTS from 2005! 

The unfortunate part is there's such a finite amount of prototype imagery available on the internet and who knows if anyone will ever find something like this again. I want to make a single video with everything though!

@@MandRproductionsyes we need that bro

​@@MandRproductionsdew it

Great summary. @Steve9584 During my career, I worked designing plastic parts and also building the molds. There is a lot that goes into building small complex injection molding parts. I'll add two even smaller details (for anyone who cares). - There are typically multiple electrodes used to make a single mold, especially to get fine details and maintain tight tolerances. - SLA models can be very accurate with tight tolerances, but the plastic used to make the models are very brittle. Even though an SLA model can be very close to a final molded part, the plastic itself does not act in the same manner. For example, the painted SLA of the guard (5:43) probably could not be placed on a minifigure toros without cracking.

Hello, plastic injection mould maker here. The description if SLA is absolutely correct, I'm going to add some clarification to the EDM description, having used one myself reasonably often. They would very likely not use both halves of the mould at once around the electrode, they would sink the electrode into each side one half at a time. This is because there will be a significantly better surface finish, because this process actually burns the metal rather than slowly melting it. (Think of a tig welder with the amperage way too high) The insulator liquid, back in that time would have been oil, now its distilled water, serves another purpose. Washing. There's a lot of black soot created during this process and water or oil jets that are pointed at the electrode where it meets the part are washing away that black soot. If this isn't done, the surface finish will be terrible and production speed goes way down The EDM electrode it's DOES actually shrink, but it's a known value associated with the surface area and amperage used, so it's calculated into the CAD design and machined a percentage larger, so the finished size is exactly the desired size. The amperage is also predetermined by the surface finish desired on the finished part. Lower the amperage, smoother the part, higher, you'll get rougher finishes. Think of those old 2x2 and 2x3 slope bricks with the texture on the sloped part. That's a higher amperage EDM electrode doing that.

Thank you. I knew what SLA was but wasn't sure about EDM. I thought it was a bit lazy for someone to make a RU-vid video without even a 60 second Google search for terms they didn't know prior to filming. I suppose it can be considered more of a "reaction video" than something meant to educate though.

I believe you have to be a mega LEGO shill and then maybe they'll show you behind closed doors. I'll never get that chance I guess lmao

Now you have to be a mega LEGO shill to get them to interact with you, it is indeed very sad to see as someone who’s been in this for ~20 years.

😂😢L😢😢😢😮😮😢

🎉😮😅

Oh my god they’d make so much money

Yes. SLA is short for StereoLithography (Apparatus), a type of 3D printer.

Came here to say this too! I work for a plastics trade mag.

To be fair the original presentation doesn’t exist in video format and if it did it’d be 240p and Black and White 😂

@@MandRproductions 😂 the video would definitely need more jpeg!! All jokes aside though, the prototypes were cool to see. I’d love to see more if you’ve got them!

No but you gave me an idea lol

Soon soon!!
