So then post the model online and see what Ultimakers can do
Or just send 2-3 Volunteers the file. I would agree to print this and take some pics.
Btw the upper part in your picture is more or less very hard for any printer to print nicely if not impossible
I can't post it publicly but by all means pm me your email address and I'll send it to you.

Those bad parts on the MB print look like break-away support material which isn't removed yet. I could be wrong here.
However, I would have printed it without break away support. Still, some of those details look awfully small for FDM printing.
It is. I've been sitting breaking it away with a knife but not all wants to come off.
It is a very tricky model; probably the most complex of what I usually work with. Still, I want to push the machines and see what it can do...

... Obviously I don't expect it to be of moulded quality...
Normal, I don't know, but it is definitely not unseen to have prints of the detail level you are asking for come out something like that...
3D printing is NOT an "out of the box and everything will be dandy" kind of thing, and to print models like the one you have posted there in that sort of detail will require both experience and skill (the two go hand in hand really)...
Can it be printed better than shown in the picture? Definitely. Will it ever live up to your expectations...? Hard to say...
I'm wondering if you are maybe expecting a bit too much from the technology, a sort of "this could/will be the tool that will solve all my problems and headaches" approach...
In the end, its a machine that presses molten plastic through a 0.4 mm. hole that moves... There are limits to what it can do, and again, those limits are reached through a lot of tinkering...

Look at the objects posted here:
Scroll through all 77 pages of 1700 posts...
Going through the posts from the back. This terminator head is the only one so that shows the detail I'm looking for:

Hello Sebastian
But I think the following well:
No one at MakerBot has obviously trying to distort the result.
It is actually not clear whether in fact optimal settings were used for reproduction.
I also suspect that no one has made efforts to replicate this object as possible. There are simply too many factors to consider. Unfortunately, objects have to be adapted to the capabilities of a machine. I do not know any machine from MakerBot / Ultimaker / etc, which dissolves finely identical in all three dimensions.
It is not the first time that I see such patterns.
From basically good machines, terrible object pattern are sent. Perhaps the manufacturers simply lack trained personnel, an appropriate section, and or enough time.
I could put no conclusion from this result, which judges about the overall machine quality.
One conclusion I have, however: Some manufacturers believe it is sufficient to be able to build a good machine.
But it would be good to see how close our most experienced users come here to the original.
In parallel, I would like to see what the most experienced MakerBot users can do with their machines.

I tend to agree. I don't that the reseller was the best at 3D printing. He was very helpful. He knew what he was talking about. perhaps though the practical side lacked some experience.
I think the part was also printed way too fast. Seriously I'm not that interested in speed... quality comes first.
My gut tells me it can do much better but lack of experience and time constraints made for a shoddy print.
-
Ok I'll have to get permission to post the model.
The sample doesn't look right to me though. Hopefully I'll soon be getting the sample from UP reseller. Curious to see how that will come out...
-
Yeah I'm very interested in opinions of non-MB users too...
-
This is not a dig at Makerbot :!:
I sent a model of one of my projects the local Maketbot reseller to have a sample printed. My line of work is injection mould design and related product design (so mostly thin-wall stuff) so printing toy rockets and the like is not really a good test.
I received the sample earlier this evening was quite shocked to honest. Its nowhere near is good as I expected. Obviously I don't expect it to be of moulded quality but this was quite poor. I have uploaded a screenshot of the model and a photo of the printed part. Note the circled areas in the screenshot.
Is this result normal?

^^ sorry :/ fat fingers on a samsung keyboard...

Absolutely would lovevtovseecthe Zortrax review!!
-
Ok. Is that the only glaring difference for you? What is the quality of the parts coming off the UP? What material do you use?
I saw a video on youtube where the Y-axis (supporting the table) seemed to flex up and down. It was very slight and possibly just a play of light and shadow but in your opinion how stable and how accurate is the UP? I know this isn't injection moulding (my usual stomping ground) and I'm very familiar with CNC machines so I know all about the precision issues of rotary scale and backlash... I don't expect absolute accuracy. However I'd like to get as close as possible. Any and all information is welcome.
Just so its been said I have short-listed the following:
-
Airwolf AW3D HD
-
Makerbot Replicator 2x
-
Ultimaker 2
-
UP Plus 2
-
Zortrax M200
I have contacted all the manufacturers and suppliers for the above but would appreciate feedback from users too.
-
-
Compared to the UP's 150micron Z resolution, more than 7 times better.
How many people actually print at that resolution? 0.1mm is already pretty small...
-
Then you need another supplier.
My mistake. He said that only the mini had an enclosure. :oops:

Hi Sebastian,
When you read about any units arriving broken/knocked about you probably also read that Ultimaker took great care of its users and we left nobody in the dark.
When a printer arrives damaged it is usually due to rough handling, something we can not always prevent.
But what is important is how the company you committed too, handles such a situation.
There is no official reseller in Cape Town, South Africa.
But we can ship it there.
Thanks for your reply Sander. Yes, you're right. Recipients of damaged printers all said that they were looked after promptly. My concern though is that I am very far from Europe and it'll take so much longer. Whatever machine I decide to get already has plenty work lined up and I can't afford for it to sit idly...
-
Thanks for all the feedback.
I have read on this forum about problems with delivery i.e. printers arriving broken/knocked about. Not good for a device that has work to do. Also I want to find if there is a local reseller. These are my two main concerns.
-
I am also a huge fan of Moi.
-
Reading this thread makes me wonder if it would be wise to order one. South Africa is a long way for services should it arrive broken. Unless you have a South African reseller...

I am not sure exactly what you are doing, but it sounds like the SHELL feature would help, you can import an object, make a little flat spot and tell SW you want to make a shell of the solid piece, all you do is provide the shell thickness.
This one is close. Model your phone as a solid then convert to surfaces. Trim away everything you don't want as part of the case. You will now be left with a surface similar in shape to a flattened rectangular soap dish. Offset this surface outward by whatever thickness you want the case to have et voila.

As a professional designer I have used many CAD packages over the years; both proprietry and free. If you want free you might well get away with using Autodesk 123D or Creo Elements.
However I use Geomagic Design and Moi in my business. Totally swear by them.

I plan on getting a Sense in the near future...
-
This is the only one I have "on tap". It's an old test print series I did for someone looking to buy the original UM and wanted to see the difference between layer heights. Someone else will have better pics I'm sure.
Exactly the sort of thing I was looking for. Cheers!
-
You can see a print here
But I am sure someone has better pictures?
Basically 20 micron doesn't show any layers anymore.
That first one is pretty cool.
-
They BOTH have heated platforms, the mini to 50 degrees and the UP plus to 100 degrees.
On the UM2 you can set whatever platform temperature you like.
Really?! The reseller was very specific that only the Mini had a heated platform. If what you say is true then the Plus is starting to become a true contender...
Much homework to do this weekend...
-
Thanks.
Just spoke to the local UP reseller and oddly he recommends the UP Mini over the UP 2 Plus due to the fact that it has a heated platform. Apparently it gives better quality finishes.
I am blown away by the Ultimaker 2's 20 micron accuracy. That is extremely good for the amount of money. Anyone care to upload a close-up photo of a part printed at that resolution?
We definitely will buy a machine soon. Most likely in the next two months so we want to get all our ducks in a row...
Keep it coming!!

To all that replied here: thank you so much for your input. I have decided to purchase a FlashForge Creator X. Its a good machine with dual extruder and most importantly a local reseller.
Thanks again. :smile:
