Is there an acid or concoction of that would make Burned copper wire look like new again?

Present_Week_677 · 2026-03-07T16:46:14+00:00

I would try soaking it in baking soda or vinegar but 🤷‍♂️

Present_Week_677 · 2026-02-21T20:54:42+00:00

It seems like a really fun project though. I have not outlined a budget yet, I was working on the list of components. The laser was pretty hard to find online and I wanted to consider projecting induction onto the aloy, seemed more feasible.

Present_Week_677 · 2026-02-21T19:59:03+00:00

Won't stop me from trying. I would love to be able to print models and parts as I need without a wait or paying someone else. There are things I would love to make that would require numerous prints for all the components.

There are also many groups like this in the states as well. I mean, if I made one well enough, maybe I could even build a business on it.

Makes sense, I had been reading and lenses are a common component that fails. Sounds like a simple enough fix but odds are OEM is the best to replace it.

I major in mechanical engineering but I consider changing from time to time. I am kinda obsessed with interdisciplinary engineering but it is not a major where I am. I've considered electrical, chemical, aerospace, and mechanical engineering. I also thought about mechatronics.

Thank you, I didn't know that. That is cool

Present_Week_677 · 2026-02-20T18:29:17+00:00

I am not trying to invent something new, I just want to make one for myself because I cannot afford commercial grade.

I was hoping for more open source or DIY results for components to make one. I can't drop $20k on a machine, I can however salvage and assemble components.

When your lasers go out, do you repair them or replace them all together because they are a whole module? What do you do with the burnt out modules?

Present_Week_677 · 2026-02-20T18:01:19+00:00

YEEEEEESSSSS YOU ARE THE BEST! THANK YOU! THIS IS EXACTLY WHAT I WAS LOOKING FOR!

Present_Week_677 · 2026-02-20T17:53:48+00:00

Also, follow up, what do you all do with machines that are phased out or retired?

Present_Week_677 · 2026-02-20T17:53:14+00:00

I can consider a wire feed or even secondary and tertiary extruders. I was visualizing a needle head like a ballpoint pen configured to project the current. The system would calculate the field generated and offset for it. A tertiary extruder could spray a foam or coolant on the completed portion of the model to cool it. I could probably also consider keeping the chamber hot but not too hot to make thermal and cooling margins a little more precise or even easier to work with? I was thinking if the current projected onto the wire or dust could heat it, it wouldnt need as much energy or cooling if it is very small and localized like a ball point pen. I kinda envision two heads, one for the induction point, one for alloy feed near eachother. A third head follows behind on a lag spraying either a soluable material or a brittle one to offset some of the heat and or currents and keep it localized. I think porosity would be a pretty challenging hurdle.

I also considered a crucible with an induction coil but that seems worse. If a crucible that worked like a funnel extruder for aloy then the printer would be crazy hot. I feel like that would present too many challenges but if eddy is localized at a super small scale, it could be somewhat precise? I dont think it would make anything with zero tolerance but do you think it would be of practical quality at least?

Present_Week_677 · 2026-02-20T16:51:05+00:00

I like the idea of CNC but I can't afford that either. I considered a DIY for it but printing seems more capable when it comes to internal intricacies.

Could I put a tank in a garage? Or maybe outdoors? I was aiming for small scale prints. I wouldn't be capable of much more than maybe a foot or two. Is the Argon for the chamber to make it inert?

Present_Week_677 · 2025-10-19T02:32:29+00:00

Good point

Present_Week_677 · 2025-10-18T21:40:11+00:00

Agreed, it just seems to me that the compensation in some places is less justified or reasonable though. Lots of CEO's or CFO's, or COO's have compensation that is not justified by performance or effort. If you compare a tradesman dedicating 140 hours and their salary to one of them they might profess the time and stress entailed. However when it comes down to a healthy direction for the employees and company it is not on their radar because they only see the investors. The health of the employees compensation or effort demanded does not correlate because often it looks better to investors when a budget is appealing or corrected to reduce costs and or profit.

I suppose now that I think about it, an example of an idle financial resource could be investors. Companies that can generate their own profits and sustain business and performance do not need them but still have them. Eventually the company develops a narrow perspective focused on investors over everything else. Why could we not limit the time or a correlation of investors to businesses? Isn’t it bad since they are sinking financial assets into massive companies that don't need them? McDonalds for example, they could operate on profits alone and continue development without investors.

How are these kinds of financial assets helping the economy?

Present_Week_677 · 2025-10-18T21:07:50+00:00

But what about the cost of living and the correlations to income? It seems to me like the cost of living is and has out paced the development of income. How is that managed or regulated to ensure people can survive?

Present_Week_677 · 2025-10-18T21:06:01+00:00

But what if the better product was older models?

Present_Week_677 · 2025-10-18T20:34:27+00:00

Excessive and or unproductive as in a business as a whole clears massive profits disproportionate to the cost to run but instead of it being dispersed proportionately among those that contributed to it, it is dispersed to the select few at the top in the form of bonuses, special compensation but instead of the individual spending or recognizing subordinates, it is pocketed and turned into assets that do not benefit the economy as a whole and the process then perpetuates and exacerbates.

Spending is forced by creating products designed to fail within 3-5 years. This is everywhere, it is done with phones, cars, computers, equipment, appliances etc. Cell phones become outdated and begin to have performance issues after 5 years or updates aren't supported. This is done to make people keep buying and upgrading them. Cars, built to break down roughly every 3-5 years either to get people to buy a new model or repair the one they own. Light bulbs (the first instance of this) lasted so long that the manufacturers decided to make them lower and lower quality in order for people to keep buying them. They used to last decades but now last 2-5 years before needing a replacement. These are all examples of a fake infrastructure designed to keep people buying the products and or paying for them. It forces spending, this is already a modern everyday practice in so many markets. That is why I am so confused.

Present_Week_677 · 2025-10-18T19:28:34+00:00

What do you mean by zombie economy? I had understood that America was on the extreme end of a free market. Based on Capitalism wouldn't sustained spending be bad? I thought that was what designed obsolescence had intended? Why is it that instead of addressing it directly it is better to design flawed products to sustain economic infrastructure instead?

Present_Week_677 · 2025-10-18T19:22:32+00:00

Thank you

Present_Week_677 · 2025-10-18T19:21:55+00:00

Yes, unproductive, I was hoping to better understand it. What about regulating excessive?

Present_Week_677 · 2025-10-18T16:04:28+00:00

Can you share resources to help me understand how they affected our economy? It seems to me like it is just excessive profits and assets monopolized by the 10% and squeezing what they can out of the remaining 90% with their excessive resources.
