remember with out our printers 3d hubs would be nothing you have a voice there is no benefit that i can see for a hub with the new rules apart from more work for us.
I think you and @Vienna3DPrint have hit the nail on the head. 3D Hubs has forgotten it’s role in all of this. The reality is my customers will come and go with me, especially if I discount 12.5% from my prices if they place orders outside of Hubs. Like you, I try to keep all my orders through 3D Hubs, with the very small exception of those who need to pay by other means (which is common with younger students). Hubs is supposed to be what Etsy is to their shops; Etsy just provides a site and a gateway, the shops do all the rest. Etsy does not own the customers, the shops do, and if the shops leave, so do the customers. It is very much the same here, but 3D Hubs seems to have forgotten that, or doesn’t care anymore because they got their funding.
Either way, the entire handling of this situation has left a very bad taste in my mouth, and I am very displeased to say the least.
From what I’m reading here, it only strengthens my opinion on this as I see I’m not the only one operating this way. I too have requested to do deals outside 3D hubs but I push people to use it for its interface and organization. The way you guys put it is exact. The hubs are 3D hub’s customers, not the people buying parts! Unless they want to hire their own massive sales department to replace all us hubs I suggest they start listening. Until now I’ve not had reason to look into other platforms, and I’ve promoted 3D hubs a lot. This may incline me to look elsewhere to do business.
Hi
Well, that´s all a good intention, but poor execution. Why ? Because since now I was on the lower end of the price range. I could do that, because I have a full time job (that provides me and my family) and offer my 3D print services in my spare time. Therefore I asked my customers if they want to remove the support material themselves (to get the prints faster) or if I should do it (and they would have to wait a little longer). Often I didn´t even charge the support material for smaller prints. Only for bigger objects with a lot of support and time taken to remove it, I charged a small additional amount. You could say, the time spent for it was for free. Because average EU/US hourly rates for labour would be like twice to five times of the value of the print (guessed…)
It was good that the people could choose, because often they wanted (or had) to improve the print by sanding, painting or other methods. Now this choice is gone. And due to the nature of the producing machine (desktop home use) and method (FDM is the least accurate!) it will cause only disputes printing with non-dissolve-able support material. That makes it about impossible to use a single print head machine.
On the one hand it would be the logical next step for me to upgrade to a dual head machine. On the other hand it will make 3D prints MUCH more expensive for 3D hubs customers. Water dissolve-able support material costs 3-4 times of PLA filament. The dissolving takes about 12-24 hours (if I am correct). Higher and high priced hubs may print already that way and will keep their high price. But the possibility for cheap and fast prints (with customer removing the support) is gone with the change of guide lines.
That is NOT supporting the spread of 3D printing.
I don´t even want to speak about tolerances. It´s quite the same as with 2D prints. What kind of quality can you expect from a €/$ 50,- Printer ? People are then disappointed. Prints are not seamless, have wrong colors, are washed-out, a.s.o. You still have to invest at least 10-20 times more for a decent quality.
So, how can you expect extraordinary results from a €/$ 800,- 3D Printer ? (This average price is a guess. You might have better statistics).
A really awesome FDM print needs a CAD model that considers the abilities of the used 3D printer. It has to consider physical laws. The 3D printer has to be set up in terms of even and balanced print bed, correct space between needle and bed for the chosen resolution, prepared (sticky) print bed, correct temperature for the used filament. The slicer have to be tuned for optimal feed, speed, calculation of the g-code. The filament have to be of good quality. Maybe stored in costly ways (vacuumed). The print environment can have a big impact on the printed results (temperature control, humidity). And maybe more I haven´t considered here and now.
It makes the impression that DIY tools should reach top-professional high end industrial standards.
I don´t want to say that the aim doesn´t impress me, but now the vision has to meet reality.
It is not possible, for a reasonable price, to fulfill the announced standards. If you want the requirements to be met (seriously), then the hub must charge hours of pre processing with a lot of information transfer. Maybe some information is not even available because the customer has also only the stl file. Very often the stl is not water tight. So you need additional tools to repair it. Then, to finally meet the tolerance, a couple of prints (which blocks the machine naturally) to maybe recognise that the tolerance CAN NOT be met. And you can only tell after the support material is removed.
All that costs the hub time and money.
A small 10x10x10cm object could cost likely more then €/$ 250,- if requirements must be met.
This results in three bad things: High prices for FDM 3D prints. Less orders and revenue for hubs. Less profit for 3D hubs.
I would strongly suggest to not activate the guidelines for FDM by Jan. 5th, 2017. Rethink the role of 3D Hubs as a broker between clients and maker.
Refine the platform to be able to choose between instances of print quality. Collect and present possible print outcomes for customers. Not for hubs; they know them just too well.
Thank you and happy new year.
lol no worries I was just adding to your post
I’ve actually got an interesting example of the dimension problem right now. The part has a shaft running through the middle and the part itself needs to fit tightly inside a tube, so both the inner and outer dimensions of the cylinder need to be spot on. The client has provided dimensions, but I’ve included what happened on printing (see attached).
Some of the dimensions are OK - the flange at 0.07mm too high is irrelevant for this model for example. The major issue is with the internal diameter that should be 15mm and prints at 14.4mm. I’ve corrected this in the model and it now looks OK, but what’s important here is that all of these dimensions of the printed part are within the 1%/1mm guidelines, even though as printed first time the print was effectively useless. (note, I know some of the dims don’t add up, I’ll put that down to variations in printing thickness and/or lack of coffee).
@Robin3D how should we deal with prints like this? Should we charge more for dimensional accuracy beyond the guidelines, how do we charge for modelling, measuring, testing, etc.?
Please just place somewhere in the guidelines: All services are based on best effort by the printing hubs.
That will not put an end to complains, but release the pressure from hubs and puts everybody on the safe side.
Thank you
There should be an option for the customer to select removal of support material or not and have it priced upfront. Also, support material needs to be factored in the price at the start as often times I have parts that have more support material than part material! Finally, customers who choose to print at 200 microns for cost reasons seem to expect 100 micron resolution and may complain.
Maybe there should be two tiers here. Professional hubs with$10K plus printers who can produce professional results and charge for it and Hobby Hubs with Hobby level machines that produce good quality but not at the level of the Pro hubs and charge appropriate prices.
Unfortunately the price of a printer rarely gives an indication of the quality of the print. I have seen prints come off 100k machines that are good for nothing but the bin and incredible prints come off a well tuned £300 printer.
Unrealistic customer expectations is another wonderful discussion point. Unfortunately with the perception of 3D printing in the wider world that it can do anything and is instantaneous it’s a real issue to bring home the reality to a customer.
