1. “discussed with a lot of experts as well as a good amount of Hubs” Please ask some of the experts and hubs you discussed this with to join the discussion here, otherwise this is just a straw man “people are saying this…” argument.
“It’s not standard practice we ask all Hubs for input on changes.” Well, it should be. It’s called “voice of the customer.” Its the only thing that prevents a competitor from taking your market away. You also refer to this as “the change.” Meaning it is now policy, not a test. If I could just get you to admit it!
You did not answer my question, which was “Why did you not get input from US on this change?” Your answer that it is not standard procedure is indefensible on such a broadly sweeping change, that affects the greatest majority of your existing hubs.
5. “without harming existing audiences” is not the same as not harming existing hubs. This change harms your best hubs, who print the best quality, and in the materials your FDM market serves.
6. “We implemented the FDM guidelines already to prevent a decline in print quality” Actually, that’s the opposite of what you said the results were. You said “We started with the latter by adding an excerpt to the checkout a few weeks ago, that highlights FDM limitations. What we’ve found is that, if exposed to these limitations, no fewer FDM orders are made, but print quality ratings do increase. In short, it appears that the excerpts succeeds in setting customer expectations better.” This means you made changes to what customers should expect. You did nothing to prevent a decline in print quality. In fact, lowering the expectation means better reviews for poorer prints, better rankings for poorer prints, creating additional competition for high quality FDM hubs. You have not done anything to increase the quality of prints. You cant say you are lowering customer expectations and getting better reviews, and then say its increasing the quality of the prints. You are saying that because we told people they are going to get bad prints, they are happy, so they must be getting better prints. This is faulty logic that assumes a correlation between two poor connections, and I know you are smarter than that.
7. I don’t think you “completely understand my view” as you say. Following that up with saying “the data” supports you is another straw man argument. Since I have stated I am suspect of the motives of 3dhubs here, and you have no way of actually sharing any data, this is an invalid statement. Directly, you failed to answer the specific question. Let me rephrase it: “Please tell me specifically how your data shows that an FDM hub with hundreds of prints and perfect reviews will benefit from these changes” Saying your data shows that customers are returning to hubs, that reviews are going up, everybody wins, etc. is not a metric we can trust. “A rising tide lifts all boats” is fine. But not in business. I want you to explain how your data outcomes are different from my views, specifically. You said it raises the reviews for poorer prints. If you don’t answer this, all your other statements are an attempt at calming us down, when you are really trying to denigrate FDM in the marketplace in an attempt to get higher margin prints.
8. How did you intend it?

Finally, stop saying you are going to “do more nuanced copy.” If you don’t say you are removing Prototyping, stop sugar coating it. The truth is, this policy is here to stay, regardless of the input.

I know it’s a small segment, but that (product design, engineering development) is the market I think 3D Hubs is trying to get into and therefore, that is who they are catering to with these changes. They have already cornered most of the other markets I mentioned, hence the changes we are seeing here.

I did not say your printers are sub-$200 printers (non of mine are either, especially my Axiom), what I am saying is that it is now very cheap to buy FDM printers (and the material for them thanks to eSun and other Chinese manufacturers) versus a few years ago, when really only established companies could afford them. So why spend more than $200 on a Hub order when you can buy a printer for that price (especially if a maker/hobbyist plans to do a lot of printing)? Obviously, there’s no guarantee of any print quality with that route (especially with the cheaper machines), but makers/hobbyists who have time to learn the ropes are taking that path more and more frequently. In my experience over the last few months alone, that income source (the maker/hobbyist) is drying up a bit due to the the low cost of FDM machines. I can definitely see that being a motivating factor here, and agree with you that is not necessarily being implemented properly if this is the path they plan to take.

FDM hubs and FDM prints make up a huge portion of 3D Hubs (based on Hubs’ own data, here 3D printing trend report | Hubs), and pushing changes that hurt these Hubs will negatively impact 3D Hubs themselves. Looking for new user bases is a very important part of growth, as you know, but it can’t be done at the cost of the original base and the Hubs themselves, which is where I think all these issues discussed here are stemming from.

@Vienna3DPrint You are an FDM hub with good reviews. You are not a benefactor in this change. You are now a low quality prototyping hub, sorry.

Yes, @Enza3D, I know you were not calling my printers $200 printers. And you know my modified printers, if you have seen them on all the other forums, are definitely not $200 printers.

To your other point, I have many repeat customers, and more than once I have said “Well, you’ve printed enough to buy a good solid printer” and they always say “not for me, I just want the parts.” A 3d printer is a pain in the butt. They don’t want to get married, they just want a part.

On the other hand, I just spent all day (which is why it took me so long to respond today) with a fortune 100 company, where they are installing $100,000+ printers. See, they have software people, CAD designers, etc. They are the ones that don’t need 3dhubs. They are the ones who will buy their own printers. Small and medium size businesses, who are very price conscious are the ones who do not have the correct geography for dealing with what it takes to get and keep getting 3d prints. These are my guys. They order end user items from me, and yes, sometimes, prototypes. And you keep mentioning injection molding. Many folks order FDM prior to putting their models to the molds. They do not need the in between SLA prints.
A $200 printer is not a good printer. I have seen your reviews, and your prints online. You are also not doing that with a $200.00 printer, lol. I also went through your prints, and see very few FDM PROTOTYPES in those pictures. I am starting to wonder if 3dhubs even knows the meaning of the word prototype. They definitely do not understand the stigma, and refuse to listen.

To your second point that “Looking for new user bases is a very important part of growth, as you know, but it can’t be done at the cost of the original base and the Hubs themselves”:

They don’t even know who we are. I have been 3dprinting for people as side income long before I signed up on 3dhubs. I built my first 3dprinter before Makerbot had a cupcake kit and I started selling prints. I have a lot of customers. I also am on other sites besides 3dhubs that do 3d printing, but 3dhubs has always been my home. Because they offer great software, great support, and never tried to get between me and my customers. They did the job of their manifesto discussed. This is changing.
I am pretty well known in this area, set up printers with makerspaces, given talks, helped schools, etc. I am the most prolific author on the 3dhubs knowledge base. (They took the photos. No, my prints are not that bad.) I always have had 3dhubs on my business cards. I put up posters, at my own costs, at several universities. These did not have my specific hub on it. I was just all into it. I even took some of my own customers and put them on 3dhubs, for ease of upload, quoting, etc. I am #6 in comments on THIS FORUM with over 600 messages, usually helping other hubs. I am on a lot of forums, write articles for some of the 3d printing news sites, contribute to the 3dprinting on Reddit. I am a strong influencer in this industry. I don’t see myself pointing any of that in the future at a site that says I am a prototyper, that I use “Prototyping plastics”, etc. And you should see my email inbox today, oh my some hubs are upset!

They don’t really know who we are. They think we are just whining. We have been patted on the head here. We are pretty smart. We are engineers and software developers and teachers. We run CAD machines and keep our 3d printers running, and run STEM programs. We do complicated things like 3d modeling, and robotics, and some are even lawyers who just love the hobby. Some of us handle very complex issues for our customers. No amount of " don’t worry about it, the data shows you will be fine" will make us feel better.

Because we are smart enough to understand that:

This is a zero sum game.

When a customer uploads a model, one hub gets that print. Everyone else loses.

When a bad hub gets artificial reviews for poor quality prints, and moves up on the list, another hub moves down.

If you can’t understand that we understand this simple fact, any other “keep calm and keep printing” statements will ring false.

I am not going to type much more, because I am getting ridiculous, and I am just starting to get angry about this. Suffice it to say that I stand by my first posts to a thread that I did not even start…

A: 3dhubs is denigrating FDM printing by saying the prints are low tolerance, by asking new users if they want “help selecting materials”, stating that they should have low expectations for quality at the shopping cart point, and labeling our materials as “prototyping materials”. They are doing this to push customers to do higher margin prints. They are doing this slowly and methodically, and hoping FDM hubs, or competitors to 3dhubs.com do not notice.

B. 3dhubs made a sweeping change that only benefits them**, and they did it without any input from US, and will not use different terminology even though they know “prototyping” is distasteful to the quality FDM hubs, because nothing we say will matter to them. As of today, its been up for 3 days****. WOW. And most hubs don’t even know about it, YET.**

I really like your solution.

I do have to say that these issues we’re experiencing now were really foreshadowed back on our forum page a few months back, with the lack of response for several weeks over our concerns with the new idea for tolerances, which were then promptly pushed out with pretty well a blatant disregard for all of the concerns raised.

I do agree that it is misleading, and unlike some of the other people in this forum post I do believe it is intentional. 3D Hubs makes more off of the one time big shot deals than the would off of several smaller FDM deals. It’s just common up selling techniques being used, customers pay more money then 3D hubs gets the same proportional slice of the pie, but in this case the pie is bigger.

By pushing SLA and other printing methods over the cheaper alternative to FDM they increase their potential revenue. This is unfortunate to see as for a while the 3D Printing community really truly did seem to be solely focused on getting the customer 100% exactly what they need and what suits their projects best.

I also disagree with the statement ‘visible lines’. I can get my fdm machines to do layer heights as low as 20 microns, and at that point the layers are invisible unless you look extremely close, and are fine enough that you can’t tell by the touch.

Not a happy hub either. My orders have dropped since the change as well.

@Enza3D, I like that idea too, but can we trust 3dhubs to write the descriptions in a fair way? BTW, this is your idea, that is not what I was suggesting. I was pointing out that they used prototyping as the only “outcomes based” description of the materials.
HQ, Flexible, Prototyping. One of these things is not like the other.

--------------------

@imagine3dps Those are some fantastic prints you have on your hub! Those are some of the finest “low quality prototype” prints I have ever seen!
Nice hub, nice work!

This is most likely the result of including “retention” into the Hub rankings, see changelog. The checkout does not appear to influence overall FDM numbers (see my earlier comment). Feel free to nudge support@3dhubs.com to find out about the cause

@PepCo_Parker Excellent prints, excellent reviews, wonderful work. I see you are also a person who has posted over 100 times in TALK, which means you have probably put more time into 3dhubs TALK alone than you have made in profits.
I think 3dhubs should spend more time working on helping you make more money, since you are a good contributor and a good hub, instead of trying to steal your customers.

Thanks Perry. I wouldn’t say they’re trying to steal, mostly just redirecting. You’re right about the time by the way. If I counted my wage hourly my company would be in the hole ten fold. But that’s just part of the investment I’m putting in with hopes of receiving return later on. Would be a real shame if that never does happen because the majority of orders that should be fdm are scared off to more expensive methods.

From one of my repeat customers today, who is willing to speak directly to 3dhubs management directly if they are interested. This was unsolicited from me. He wanted to know why I was moving to cheaper materials.
He missed the whole point that this was a 3dhubs change, he thought I had changed to lower quality materials. I guess this is a a result of the materials now being called “Prototype Materials.”
This is the same customer that pointed out to me the new “Can I help you choose a material” dialogue. (A solid repeat customer that 3dhubs decided to try to upsell to another material! Which also would have lowered my rankings, since I get points for a repeat customer…)
I did not solicit the call. What is the funniest part of this? This is a customer I actually do prototypes for! (He then gets the models milled in aluminum)

Let me be very clear on what happened with this customer, a good 3dhub customer.
Last week or so, he went to create an order, and got a dialogue box that said “Can we help you select a material?”. This would have presumably tried to push the customer to HQ. Taking my repeat customer to another, higher margin hub. Literally stealing a customer from my hub, that I have worked with for over a year, and then dinging my ratings for not gettting the repeat.
Today that same customer called with an inquiry as to whether I have lowered the quality of my material.

Hi Simon, thanks for the suggestion, happy to iterate / debate. In your suggestion, what scenarios would you recommend customers to go non-FDM? Or do you feel the technical specifications should be leading there?

I’m pleased you pointed that out!!!

I put all my customers orders through 3D Hubs. My website points customers to my 3D Hubs page to upload their files so all website orders go through 3D Hubs system. I thought I would test the system as my orders have dropped off (since the changes) and I am disgusted at what I found…

Basically acting as a customer I added my files, then I selected my material and colour, the price looks ok so I go to the next page and see the attached!!! 3D Hubs pushing my customer away from FDM and towards SLA and SLS again!!! Needless to say the links lead through to choosing SLA or SLS hubs.

This is bad when a customer finds your hub through the 3D Hubs platform but when the customer comes from MY own website to place an order on MY hub only for 3D Hubs to redirect them to someone else is disgusting!!!

This doesn’t seem right indeed. I’ll look into it asap

Blind loyalty is Fandom. Like here in Cleveland, where we have the Cleveland Browns.
Actual loyalty is a two way street.

You can look through my posts in the past here on talk, where hubs ask “Why should I keep my customers on 3dhubs” and “If a customer wants another print, do I have to keep them on 3dhubs.”
I immediately wag my finger at the questioner. “How do you think 3dhubs gets paid?” “This is cost of sales”. “Supporting 3dhubs helps them improve the software.” “Always stick with whoever brought you to the dance.”

Hi Simon (@Steelmans), I’ve been told the links have been removed, can you confirm?

For SLS the main advantage has be not needing support material. I recommend customers go to SLS when models require complex support that cannot be removed easily, for example inside cavities.

I recommend customers go to SLA when they require very small detailed features that not easily produced on FDM, for example jewellery or dental.

(By the way, I am not suggesting you should rename “High Detail Resin” with “Jewellery Resin” as this would be unfair on SLA printers, Much the same as “Prototyping Plastic” is unfair to FDM printers.

Clear, will discuss your ideas here. I do think SLA deserves a ‘smooth surface finish’ highlight as well, as many customers use it to get a sense of what an injection moulded part would look like, would you agree?

For Q2 we’re also looking into possible splitting current material groups into a 2-step technology + material selection flow. In that scenario, FDM will probably just be called “FDM”, which might be the most objective of all ideas.

Yes SLA does deserve “smooth surface finish” but it is more a capability rather than a standard feature. Remember some SLA machines can print at higher layer heights too.

Calling FDM just “FDM” seems odd but it depends how it is displayed. Maybe is will be listed as just FDM, SLA and SLS. Why not revert back to “General Purpose Plastics”?
