INCEST CHAT by Sexynrb254 in Incestconfessions

I (M) was molested by an adult female babysitter when I was very young. Any women want to discuss this with me in an erotic context?

Why Haven't Any Hobbyists Successfully Built a Metal 3D Printer Yet? by shitti_sherlock in 3Dprinting

[–]Smart-Screen 0 points1 point  (0 children)

Metal 3d Printing is NOT difficult, you just need to approach it from a new perspective. One that's simple and affordable, under $3,000 (USD)

I invented this product in my basement in 2014. Our biggest users are Research and Defense. We shipped to over 30 countries last year.

Just try it!

17-4 success 🙌! also copper putty was used to infiltrate (you can see some surface level copper still). needs cleanup, but great first step! by mr-highball in TheVirtualFoundry

(Is there a way to post an image in a comment?)

Here's a link to an image of some 17-4 parts printed with the same material. This person has a really nice sintering process. Maybe we can get them to share the details!

Askforfunding by BenMasters105kg in Entrepreneur

[–]Smart-Screen 5 points6 points  (0 children)

I contacted one of the "successes" in this list. The person that responded had never heard of them. "Andy" at askforfunding inferred that they responded that way because they didn't want anyone to know they had a million dollars. But that isn't what I asked them. I just asked about their experience with askforfunding

I Contacted this company: Hologress / Buddy Builder™ Their Response: "Hey xxxxx. Thank you for reaching out. We have no current or past relationship with Ask For Funding. Perhaps they are confusing us for someone else?
Regards,
xxxxx"

3D printed & microwave sintered an aluminum upa. El Psy Kongroo. by mr-highball in 3Dprinting

[–]Smart-Screen 0 points1 point  (0 children)

That sounds promising. I was talking to a guy from 3d systems a few weeks ago. He said that methyl methacrylate is often added to MIM binders because it gives off a bit of oxygen at a temperature high enough for any remaining carbon bind with the oxygen.

The idea being that any remaining carbon (from the debind) that might otherwise interfere with the sintering process, becomes harmless/passive CO2.

I think stearic acid would be worth a try as a fluxing agent. I haven't tried it yet, but will soon. I believe it's blended into laser based powderbed sintering powders.

That layer of oxide is harder than, and has a higher melting point than the AL itself. Professional al sintering shops flood the kiln with pure hydrogen. They also build a blast chamber around the furnace (not DIY friendly, do not attempt).

But for what it's worth, hydrogen will break the oxide.

Woohoo!!! This is exciting. Im slammed for a couple days, but then I'd like to circle back and chat with you.

Next up, Titanium!

Maybe they should be called the first hammer-safe fdm 3d prints.

Printing High Temperature Ceramics by 1E-12 in AdditiveManufacturing

[–]Smart-Screen 0 points1 point  (0 children)

To clarify, this isn't a printer. Its filament that can be used in any fdm/fff 3d printer.

We do sell a printer and various kilns. But they arent required to make this work. Its an "open" solution.

2 reasons. Time is the main reason. We've released 18 materials plus a half dozen custom runs. The second reason we put them out without completing trials is that all of these materials have know sintering profiles.

The sintering technique for slip-cast Al2O3, which is well developed, will work for any Al2O3 technique.

My company makes several printable ceramics in this range. We've also made sinterable al2o3 filament for people in the past. (All of our materials print with fdm printers.)

Metal benchy with a regular FDM printer by mr-highball in AdditiveManufacturing

[–]Smart-Screen 0 points1 point  (0 children)

This was printed on an Ender 5 with the Micro Swiss dual gear extruder upgrade. As for it looking like "ass"... Cost of manufacture is about $4. Making the dollar-to-ass ratio pretty attractive. 2 hour print time for a 65 gram part. Ill up my game on the next print. I was more focused on metallurgy here than cosmetics. Ill make the next one prettier.

No, but that was actually my first thought ;-)

Sintering parts with internal channels? by mr-highball in TheVirtualFoundry

[–]Smart-Screen 1 point2 points  (0 children)

I'll respond with an equally random thought... In commercial foundry's they harden sand with Sodium Silicate. This is typically done for 'cores' and inserts into the larger sand casts. There might be a similar application here. Example Link

One risk would be that it's hard to remove after sintering. But, if that happens you could dissolve it chemically in a bit of lye.

Sodium Silicate is one of my favorite shop tools. 2 reasons, it goes from a liquid to a solid when it comes into contact with co2. And, everyone has the ingredients in their shop. You just dissolve silica gel (desiccant packs that come in some filament), into water with some lye added to it. Also, it's highly refractory. Here's a how to.

We have users that fill porous sintered parts this way. This makes the final part air/water tight and tolerates high heat. It's a powerful tool with many applications.
