I can ensure you that’s possible to print some excellent Marvins with an FDM machine, feel free to check the pictures below.
I firmly believe that it is a good test. It’s aimed to have an idea of the printing quality that you can provide to our customer. In your case, I pushed back your test because the surface wasn’t smooth and there were some imperfections. If you provide a similar print to a customer, he’ll probably ask for a refund.
If you have any feedback about how we should improve the Marvin review process, feel free to share it.
Hi @BHAMHUB3D Marvin can be tricky to print, but then it’s a test, so it should be, there’d be no point in having a test that anyone with any quality of printer could pass easily. There are “tricks” for printing Marvin, and they’re all here on this site, even from 3DHubs themselves. I got a fairly decent print of Marvin from a standard Flashforge Creator Pro once I’d experimented a few times, so yes, it’s perfectly possible to do a decent Marvin with FDM.
@federico3 out of interest, do you know what printer produced that rainbow Marvin?
Thanks for asking, I’ve made a mistake: that’s not printed using an FDM machine. It’s printed with a ProJet 660Pro. My fault and my mistake.
@BHAMHUB3D I’ve just finished printing a Marvin with my Ultimaker. If you’re looking for suggestion about how to improve your Marvin, I’d suggest checking here 3 or asking here
I don’t doubt even for a minute that it’s possible to get a really great print of Marvin on a desktop FDM. I am just trying to get a general consensus on other hub’s experience with their review process and their customers’ expectations. The pictured example of an FDM Marvin on the “How we review Marvins” page was a terrible print in my opinion and an awful standard/expectation to set. I didn’t think I would have any problem meeting that standard on my first print of Marvin, but later found out that the expectation was MUCH higher than I had originally thought. I am not complaining (to each their own). I just need to know whether or not I want to even participate in this 3D Hubs process altogether, and I can’t do that unless I know where my own standard “sits” on the scale compared to the popular standard. I can’t establish any reasonable judgement of that until I get answers to my question. Thanks.
Thank you Federico. I was able to get a better print. I just haven’t taken pictures yet. I will attach them when I get a moment near some decent lighting.
Hi @BHAMHUB3D it’s difficult (for me, at least) to give any advice without seeing where you’re at with your Marvin prints so far. If you can upload a print of your best print to date (and I see you’ve got a better one from your latest comment), then I’ll happily try to compare it to my best print.
To be honest, I found getting a good photo was almost as hard as the print itself!
Thank you for taking time out of your busy day to come to my thread and insult me instead of answering my question. I sure do appreciate it. We need more people like you around here. I especially like how you use a subjective word like “perfect” without any visual representation of what you really mean. Perfect to what degree?
I think it would be great if 3D Hubs were a little more descriptive about what an acceptable print is and what is not an acceptable print. Maybe some pictures of common reasons why you “push back” tests, and pictures of what that imperfection should look like instead. Like I said before, the picture of marvin on a skateboard sets an unreasonable expectation of what is acceptable, especially when compared with the green Marvin you shared earlier. Thanks for listening. I’ll get my revised print picture uploaded very soon.
I’m sorry, I interpreted your original question as “how sloppy is my work allowed to be?” or “what defects are acceptable for a perfect review?”. Perfect means none. It means dimensional accuracy, no warping, overhangs don’t sag, layers are uniform, no gaps, no bumps, layers height matches what was ordered. If you cannot do these things (which your original question, as well as what I quoted, implies) then you shouldn’t expect a perfect review. Communication is another part of the review, and if you are this easily “insulted” you might have a problem in that department as well.

“I don’t doubt even for a minute that it’s possible to get a really great print of Marvin on a desktop FDM”
It should be perfect. The quality of an FDM print is very much dependent on the operator. Maybe you need to spend a little more time learning/tweaking your equipment/software before you offer services commercially.

My original question asked folks to rate their experience. Which, for whatever reason no one has done yet. Of all the replies to this thread, all participants have seemingly avoided this question like the plague. Maybe it’s you that need to communicate better.
