Discontinued The Grasshopper

[natural farmer]

The only way I see the different materials play a role in vapor temp is how they cool the vapor after it has formed in the bowl and goes to meet them in the form of the mouthpiece…
The Ti might cool down the vapor a bit more since it is heated faster but at such short distance it should be negligible.

I can't see how it could affect the vapor production since the chamber is well insulated and the air is heated only by the sintered metal heater (copper?). I also can't see how it could affect taste…

The link Stu provided actually shows Ti has worse thermal conductivity than SS.

According to the table I linked to, at 25°C Ti has a rating of 22, while SS has a rating of 16. Can you elaborate as to how you came to the conclusion that 22 is lower than 16?

 

[ragnorokk]

Yes they could, but before anyone can say one way or another, we also need to know if any 2 of the SAME style run at exactly the same temperature. In other words, are any differences due to materials, or due to individual variations, or both?

At this point, the only valid reasons I can see for choosing one over the other are looks, weight and durability.

Although... Even weight and durability are negligable here. Your vaporizers aren't competing for the Olympics. A few grams difference in weight really only changes the heft of the device, which doesn't need to be expertly balanced/weighted anyway... It's a vape. Also, stainless steel is pretty damn durable, while TI isnt exactly indestructible. The "added benefits" of Ti in this implementation seem completely superficial to me.

Brain fart. Ti has better thermal conductivity than SS. Though those numbers are so close and not specific to any alloys that I don't think a meaningful analysis can be made on thermal conductivity alone.

I hope others don't mind that I edit my earlier post for correctness.

I've read of many people choosing Ti because they wanted a lighter vape, and several choosing SS because they wanted a heavier one. I'm not saying it makes any difference in performance, but it is as I said a valid reason to choose one or the other if the heft matters to someone.

sintered metal heater (copper?).

I think @Ratchett said it was Stainless steel?

I don't have direct confirmation, but I suspect they are using a DMLS 3D printer. I'm not certain what material they're using, but Stainless Steel seems to make the most sense to me

Yes, I suppose validity is in the eye of the beholder.

Wouldn't copper make more sense since it heats much faster?

 

[sundaddy]

But don't those metals off-gas nasties? I used to dab off of stainless, until somebody warned me.

 

[shadymilkman]

Laser Sintered Titanium if I had to guess.

We have gone over practically everything that is being talked about right now. Just read through the thread. We can't just fill this thread with the same stuff over and over...can we?

The heater is (surgical?) steel, titanium cools and heats faster than stainless steel, and my last ex is a dirty tramp!

It is interesting that we don't know if there's a difference other than the weight of the two different units. Just the mystery and larger price tag makes a person want a Ti more. I don't see them claiming 30% more efficiency anymore. Maybe I'm wrong but I remember them saying something like that.


For the record I bought a Ti.

 

[zymos]

"Just read through the thread"...
Yeah, it's only 129 pages long, people want everything handed to them on a silver platter these days!

I do think we have somewhat more complete information than when this thread was started.

For the record, I bought a purple Ti, cause I thought it looked cool.

 

[sundaddy]

I went with the SS because I'm a cheap ass. + I figured replacement parts would be more readily available.

 

[pootsforjesus]

I ordered a Ti because of the lighter weight and, I assumed, better thermal properties and less prone to dings and cuts.

And a side note, I've never understood why the "Best Of" sections aren't utilized more to lessen repeated questions concerning previously stated information. Seems to me like the perfect spot for that kind of stuff.

 

[ragnorokk]

Does anyone know what grade SS the heater is? I have not seen mention of that. I could have just browsed by it, I suppose.

 

[Joel W.]

FYI, from wiki.. Surgical stainless steel is an informal term which refers to certain grades of stainless steel that are used in biomedical applications. The most common "surgical steels" are austenitic 316 stainless and martensitic 440 and 420 stainless steels. There is no formal definition on what constitutes a "surgical stainless steel", so product manufacturers and distributors apply the term to refer to any grade of corrosion resistant steel.

 

[SlinginPaint]

My thought on Ti vs. SS is that since the Ti can absorb heat faster, it is technically cooling the vapor, and in turn providing better tasting vapor?

 

[Hippie Dickie]

i think copper is too low resistance to be a heater ... but it would be nice to know the metal used.

 

[ragnorokk]

Reading between the lines, "surgical steel" does not indicate that there's no unsafe off-gassing. That's not to say that they didn't do their research and choose the safest type for this application, but it would be nice if it was published what type their using. Owell.

 

[YaFreekin Right]

My analysis shows negligable difference. The herb chamber is insulated and identical for both SS & Ti.

There will be a minuscule difference at the pen tip where the SS vs. Ti will play a bit of a role on cooling the vapor. Any difference IMHO will be subjective.

If I'm following all of this as well.... we are working off of the premise that the Ti is better tasting and offering cooler vapor... as just recently being posted.... many folks are talking about this trying to make sense of it.... it is very difficult to wrap your mind around for sure....

So we seem to have at least consensus that the TI conducts heat a tiny bit better whereas SS is a tiny bit slower.... OK cool..... now lets explore some thoughts about what maybe could possible be going on to explain this apparent... upside down concept....

1. The heater is just south of the herb chamber {HC}.. so the sensor must be between it and the HC so now can we imagine what might have to take place... with in 5 secs the heater is going to power up and heat will reach the sensor and we go Blue....

2... Now what do we think will happen if the surrounding shell {TI or SS} can absorb heat faster than the other shell..... well my thoughts are that it {the heater} will have to generate a bit more heat energy to make up for what the shell might be absorbing away....

3... now lets take it the other way the SS vs TI shell.... doesn't or isn't able to absorb at the same rate therefore the heater meets it's quota sooner.... so we don't need to generate as much heat....

So again I do believe there will be a difference in taste and operation as actual folks who have gotten both have suggested.... Like I said though it's a bit difficult to get your head around... bit of a brain teaser.... IMO....

 

[Snappo]

Because the Ti is lighter in weight and so much more nimble between the fingers, it will naturally please the mind so much into thinking that the flavor is just superior to all other vapes! Simple!

 

[Just Justin]

Are you still on the first one?

Yup, same SS GH I've had since July and its been great, no problems and I haven't had to clean it yet and it gets used daily. I also have a Ti GH and I have been doing some comparisons so stay tuned.

This is strange if true. Ti conducts heat better than SS, so in theory the Ti should be hotter to the touch.

I wish I could shoot some IR pictures/videos of the two versions side by side. Maybe someday...

I have been playing around with the Ti GH and a SS GH and I haven't done any real, concrete comparison tests on heat yet but I can't really tell much of a difference between the two. I hope to add some more information regarding the heating and cooling of both units but so far I would say the heat differences are minimal.

I plan on posting more about the differences between the SS and Ti GH, heat, cooling, vapor, looks, feel etc. and I will post some detail photos so you can see the slight color and finish difference in the Ti

AFAIK, not even "folks"- ONE person had the opinion that Ti tasted better than SS..
If there's any consensus on that, it's only because a lot of people here read that and took it as fact, not because other people experienced it themselves.
