I used to be an operator at DuPont. Made a material that went into Vespel. Whenever the unit went down they were highly agitated lol. Same with Krytox

[@normang3668]

The cost of Vespel seems to be tied entirely to its versatility... I'd be curious to know what it costs to actually make the material.

[@flikflak24]

Probably 150-200 dollar a bar but since it's so rarely used and therefore it don't get the benefit of "economy of scale" production Plus it Probably also need extreme cleaning of the equipment used to make it ( so it don't get mixed with other materials destroying its properties) which can take a long time

[@Hydrazine1000]

Probably a lot less. It's so expensive because it's worth it. Vespel is a DuPont brand name and they know they have a very high performance plastic on their hand. It's stable across a large temperature range, it doesn't outgas, its expansion coefficient is very close to aluminum, it's wear resistant and has a low friction coefficient. And DuPont knows exactly how to make it and guarantee its properties. So they charge you through the proverbial nose, because they can.

[@JamesChurchill3]

​@@Hydrazine1000 I'm sure DuPont has our best interests at heart. I'm sorry I couldn't say that with a straight face.

This is why I belive if I had my shop I would teach "make it right" instead of "make more" mentality.

This mentality put me in a respected place in a company I use to work at.

there's a company making guitar picks out of vespel called Blue Chip; the picks are amazing, they last forever and are much stiffer than other materials, they're somehow grippy under my fingers but at the same time slippery against the strings thing is, they sell for like $35 when normal guitar picks are more like 35¢!

[@jmowreader9555]

There isn’t any fluorine in Vespel, so it can’t be a PTFE. PTFE is a carbon backbone with fluorine atoms hanging off both sides of it. The closest equivalent to Vespel is Kapton. It’s expensive because it’s complicated to make.

[@tetrabromobisphenol]

The cost of Vespel is almost entirely due to the fact that you have to process it at REALLY high temperatures (above 700 F) and that the few things that can dissolve it are terrifyingly corrosive and/or toxic. Everything in the processing chain is either Monel or a Duplex stainless.

[@sb50ct]

Great video, thanks for doing it! Why rough turn, then drill, then finish O.D.? Were you finding that the material would expand a hair after drilling and you wanted to play it safe with your O.D. tolerance?

2:04 As a European lower class "Engineer"* it is horrifying to see such a drawing. Because on one side it is incredibly simple and straight forward, on the other side there is like 90% of what i have to put on a drawing just missing! The fact we got measurements of 1.495" is something that makes my Eyes burn. I do not want to start to good old Imperial vs Metric debate, but if i design a part, i try to stick with whole millimeters... seeing a 1.1 is rare on my parts... sure in Imperial with Inches ts a lot less precise... remember a Inch > 20mm... Also the lack of norms makes me feel uncomfortable. What are the standard tolerances if not specified? What scale do the views have? 1:2? 1:1? There are so many little details that are just crazy to see. A Drawing by new standards would look so different you would think you traveled to a whole new universe! Last but not least, as we have a dezent amount of milling but the part remains cylindrical outside. The part should be rotated by 90° counter clockwise.... the way it is drawn is never how you would turn or mill it inside a machine.... Amazing machining and perfect outcome as always, super cool seeing those drawings too.

[@Soundpost-f2l]

Our metric customers usually have a few oddball numbers on most parts. A .43 or a .71 or something, usually for clearance against another part of their assemblies I think. General tolerances are defined based on how many decimal places are used to specify the dimension, and critical dimensions are called out with a specific tolerance. (Like // ±.001 for parallel within a thou). Typical tolerance on a metric part is ±15 thousandths of an inch for zero place decimal, 10 for a one place, 5 for a two place and 1 for a three place unless specifically called out I think.

[@Pitstopcomponents]

@ Dont you think thats because they are Americans that arent used to Milimeters or have to make stuff in Imperial sozes but still use the Metric system? I once had to make a 1“ hole… in milimeters this would be a weird size so i just had it be 1“… the Mechanic probably has a 1“ not a 27.xx mm drill… An Inch is just much more coarse to a milimeter, hence why you often see more .xx measurements…

[@VitaminCLV]

I had an awful time once machining some weird phenolic. It wasn't the phelonic I was used to (cardboard), this shit was beige and seemed like it was impregnated with glue or something. It was tube stock. Like 3in ID, 3.5in OD, 12in long. I had to turn the OD and ID down and shorten it. Final product was maybe .100 wall thickness. What a nightmare. All facing cuts would cause the material to chip out and flake apart in the ID. I considered trying to use the live tooling to face with an endmill but at the time I didn't know how to program it and had no help. Got yelled at for all the scrap. Hopefully never again.

[@fg786]

Do you have to do some tempering before machining like with HDPE that tends to deform over time after you machine away a lot of it?

Frustrating when things are priced based on how well they work. I’m sure the manufacturer considers if they reduce the price it would hurt the sale of their other materials. I don’t begrudge anyone making lots of money. I just don’t want them to make it all on me, all at once!

I have a bit of experience machining it. At my company we tried prototyping molds with a large FDM printer that we frankensteined onto a CNC router. Printed with PLA and finish machined to size. Stuff sounds absolutely awful when being cut since the printed PLA is quite hard and brittle, but inherently FDM prints are not very rigid unless the layers are compacted directly after the bead is laid. Chatter and workholding are a god damn nightmare.

[@Titan3DAZ]

@christian6039 fascinating. I wonder how much we could tune it

[@christian6039]

​@@Titan3DAZ The two main challenges we had were being able to machine directly onto the centerline of each layer/bead so the finish machined passes would have a nice smooth surface, and the second was avoiding layer separation while machining. Had quite a lot of prints end up destroyed due to one layer separating on a finish pass and taking all the adjacent layers out with it. We tried annealing the prints, printing at higher temperatures, etc, but nothing seemed to prevent the layer separation other than simultaneously compacting while printing. Seemed to stiffen the prints up quite a lot. We eventually moved towards a tooling foam which is much nicer to machine, albeit much more expensive.

[@christian6039]

I should also mention we were using a 2.5mm nozzle so, a bit on the extreme side. I'd imagine the layer separation wouldn't be as much of an issue with smaller extruders.
