Topclass Filament, looking for wholesaler and distributor (Page 1 of 3)

First of all I'd like to say that looks like a nice piece of hardware.

Here's the thing.... Let's call it a community service message.

I have seen 450 mm/sec and I can assure you that is NOT 450 mm/sec.
80 maybe 90 possibly but definitely not 450!!!
I will go way out on a limb here and speak for the community.
If you want to advertise your new product here on our forum, feel free.
If you're going to use gimmicks and flat out lie, please go elsewhere.
There are many experts in the field that are truly valued members of our community.  I will leave it to them to explain the science behind my claims.

Well, Nice to meet you too =]

So you two don't believe the data our engineer tested, also have doubt in the new technology of fast 3D printing.

Well, I'm a sales manager, I mean not engineer or mechanical guy, so I do not know how to persuade you at that level, what I can say is, the point of our WT280S "Ideawerk Speed", is the 5 times faster printing capacity than regular ones based on the same condition, as for "450mm/sec", you have a 130mph car does not mean you drive it 130mph all the way along, right?

We have made the video to show that, but I assume that you two also doubt that too, so how about this, our company will go to CES show next Jan. surely will bring WT280S there, came to our booth, see for it yourself.

If you win, each of you can take one home for free, if I win, all I ask is we take a photo together and you post it here =]

Further more, here is an Italian company we met at last exhibition, who also released high speed 3D printer recently. FYI
http://www.dynamo3d.com/prodotti/144060 … ck-edition

Thanks for the attention, I have took 2 videos but they are too big to be attached here, and I do not have a youtube account since its been blocked in China.

Could you be so kind to help to receive them by email and somehow posted here?

Anyway, in one video it shows to print a big cube fully filled the build envelop, and when our WT280S printing its edge which just go right straight, it across the build plate which around 150mm in less than 0.3sec, that means its max speed can reach 450mm/sec.

Of course when it comes to the inside structure, speed surely slow down for the nozzle goes turning and circling.

The other video shows its average printing speed, which as I mention in previous post, the point is, its 5 times faster than regular 3D printer on the same condition.

Anyway, as I mentioned, I think the ultimate solution to prove that I'm not bluffing here, is that I will wait for you to visit us in next CES show, see for it yourself, we are confident. In fact, right now, my colleague are at ICEEB show (Sao Paulo, Brazil), our high speed WT280S draws enough attention to be reported by their local TV station.

You can make a printer that will move in X and Y at 450mm second, provided it has a stretch of travel long enough to reach those speeds before it has to slow back down to change direction.   Even so that doesn't mean it can print that fast.  They key metric isn't travel speed, but how much volume of plastic it can extrude, mm^3/sec.  It doesn't matter if it can move 450mm/s if it can't melt and extrude the plastic fast enough to keep up.

You might be able to run 300mm/s if printing .1mm layers, because not as much plastic has to be extruded.  However the print won't be done any faster than one printed at .3mm layers at 100mm/s.  So the question to ask your engineers is what is the maximum cubic mm of PLA can it reliably extrude per second for a given nozzle size?  That will determine how fast it can build a print made with a given amount of plastic regardless of extrusion width and layer height.

If you can extrude PLA at 10mm^3/s, then for .3 layers at .4 extrusion width your top speed is 83mm/sec.
If you use .1mm layers, then you can run up to 250mm/s and be extruding the same volume of plastic.   If your printer can run that fast without significant overshoot, vibration artifacts, or other reductions in print quality, then the high speed is great because you can print at a higher resolution without taking 3x as long.

An Ultimaker can print PLA up to around 10mm^3/sec.  To do .1mm layers at 450mm/s, your hot end would need to be able to extrude 18mm^3/sec.  Can your printer do that without using something like a 1mm nozzle?

I have a beat up old SD3 that can crank that octopus out in the same or less time than in the video.  I can assure you that it isn't capable of printing at 450.  Maybe if I get board I'll video a comparison.  Perhaps then you'll understand why your claims are false.  You need to take your sales manager hat off and go find a makers hat to put on before you'll understand my point.
Please remember I am only speaking for the benefit of our community.

I know I can not persuade you with any words or videos, you just don't want to believe.

Our company just present this printer in ICEEB-Brazil, and get reported by their biggest TV station.

And we will present it in 3D Printshow-Dubai next week, Booth No.:111

And of course next CES show in Las vegas. Booth No.:72335

So your opinion is that we travel all over the world to get our a** kicked?

Just come to CES show, see for yourself, I will keep my word, if it is not a high speed printer, you can take one for free.

Thanks for your attention, takes such close look at our video, appreciate that.

While we do run all three printer at the same infill rate, or else why we spend money to make this video, right?

The reason you get this illusion, I think is because when our WT280S printing the head of the octopus, the other two are still working on the feet, and because the feet part is flat, for a long distance view, it seems more infilled than the head, please roll back the video see when our WT280S printing the feet part, the same infill rate I think you will agree.

Here is the STL file of the octopus we use in the video, for your reference.

It is new technology, some times a small chip can make a huge change to the industry, agree? So far, we only know that Italian company I mention in previous post are doing the same thing as us, while I assume there will be soon many more, so we are present it to as many exhibition as we can, and seeking for distributor everywhere.

I know you guys have doubt on me and our printer, while we are confident, we spend money to make the video and go all over the world to present it, if my words and videos can not persuade you, and you can not go to any trade show, then the only way I can think about is we do it as company to company sample purchase, not so good at this situation I assume =[

Any suggestions how I can prove I'm not bluffing here? I'd like to give a shoot.

Nothing to hide, just think it is not suitable to post here in this topic, so I sent PM.

So I extracted screenshots from the video. I don't know where else to get images of these particular parts, if you have better copies that would be helpful. The first photo is your printer, the second is the Up Plus 2 that took an extra hour. Things to note:

- Your printer shows significant ringing. This is particularly visible around the eye. It is caused by vibrations that occur as a result of driving the printer at very high speeds, higher than the motion system is able to withstand. This ringing is not apparent on the Up Plus 2's print.

- The Up Plus 2 printed a raft, yours did not. This obviously added time to the print.

- The Up Plus 2 appears to have printed support for the eyes, yours did not. This also added time to the print.

Completely unfair comparison. Photos:

OK, Here we go again...

Max. printing speed is the selling point of our WT280S, like any product with a speed feature will make their ad. with its max speed as selling point.

Meaningless?

OK, maybe, but consumer buy the faster one.

OK, our WT280S print that octopus not at max speed and not 5 timers faster, but 3 times is also big deal, consumer buy the 3x one.

OK, I understand some of you don’t have time to go to trade show, but many company will, and our business will expand.

OK, maybe your TV don’t have that Brazil channel so I can not prove our success on that show, but we got us a distributor there already, http://www.acstrade.com.br/

There also are people in Brazil who put an “its impossible” conclusion first then doubting everything we said on internet, now they have to let our distributor take a bite of their profit if they want to sell WT280S, of course they can develop their own high speed printer, but that cost even more and many steps behind us.

We spend millions to promoting this printer, my team attend 15 exhibitions this year, everywhere we go WT280S draws attentions, we will see next Jan. CES show and I will post photos here.

As for the video, sorry I do not have a better copy, our marketing guys bought 2 other printers and set to the same printing parameters then recording the video and I'm not there when they do it, one of the three printer make extra support during printing  assumed to be caused by its own calculation, the other two didn't approves we did not intend to make it so, because if we want to, we shall make both other brand printer to print the support, agree?

I am done with this thread, but I did want to point out. I am not sure where your marketing managers do their research. But here in the US, as far as I have seen speed is not what people are after. They want precision, dependability, reliability, repeatably, serviceability, parts, and they want that elusive .05mm and below layer height with consistency.

As for your video, I could do the same with my phone and a few minutes in Microsoft Movie Maker and some other free editing software... It would not cost a dime and be on par with that video. In fact mine would be at 1080P. Not sure who you got to do your video but if you spent more than 100 bucks to have it done you got ripped off...

I'm sorry for the bad welcome you got here, but understand this forum is mostly composed of printing veterans who know their stuff, have built their own printer of various types and even run their own startups. Your presentation is poor, it does not supply enough information and the video is biased in favor of your model. If the speeds you claim where possible they would have done it themselves by now. Again a straight line does not count in printer speed for those who are buying a printer for performance. The time it takes to print an entire layer is what we look for and then how accurate and error free that layer is.
