[Faust]

Good evening is a new community purchase.
yesterday through our moulder I learned that at the mediaworld they sell a 3d fdm printer to 1499 euros.. .
Did any of you see her and maybe tested?
currently in the company we are evaluating the purchase of a cubex duo, you already have experience with this machine?

Thank you.

hi faust, lately we are seeing the proliferation of a myriad of cheap 3d printers.
If on the one hand it is good, in fact it is brought this technology to the reach of all, on the other hand it is witnessing the progressive diffusion of a state of chaos linked to goodness or not of a given product.

we have to think about 3d printers as a real numerical control machines, so the "real" cost differences we could meet are mainly related to mechanics and electronics .
there are on the market many open source projects at low cost and with a coarse aesthetic, the more could seem obrobri devoid of any substance, but you must think that it is precisely from these that were born the myriad printers present on the market .

personally the first thing that I value is mechanical construction, electronics and especially raw material .
if the latter is supplied in the form of proprietary coils you run the risk of falling into the dynamic of incurring in raw material costs that we all have already tested with the classic inkjet printers or toner, where a replacement of color cartridges sometimes exceeds the cost of the printer itself.
in second joke evaluate if possible print also materials other than classic abs and pla .
What not to be neglected about this type of printers the number of print heads, the cheapest use only 1 material at a time, while the most advanced can print with 2 materials .
This ability to work with more materials leads to overcoming a rock that until recently was at the exclusive docking of professional machines, I refer to the supporting material that is used to create a support whenever it comes to having non-linear geometric shapes.

in the next year I am considering to hold seminars in some schools of the territory on these issues to fill some typical gaps of this topic.

if someone was interested in assisting me even without obligation .

Bye-bye
There's another prob.
dimensional accuracy of prototypes
I have some examples where tolerance varies by +- 0.5 mm
for which the sum makes 1mm
If you have to assess an aesthetic factor, it can also be fine.
but if you have to mount some gadget I know pains
besides the fact that who then materially measures the prototype
and very easy to tell
wrong with the 3d or the mathematical model
a hug
Thank you very much

Good morning,
Thursdays and Fridays have been at the fair, 3d printers I have seen of all kinds, a pavilion was almost completely dedicated to this technology.
Most of them simulated abstract puppets and silhouettes and were no larger than a normal printer, those who had a technology that could create technical pieces with possible assemblies had another aspect and certainly cost.
I saw some of them playing metal models.

Thanks shiren of the contribution, unfortunately or fortunately having a professional printer are never in the course of such marked measurement defects.
I certainly believe that in the next few days I will be able to make a comparison as I should take care of the calibration of a 3d printer type mendel on behalf of a technical institute, say I take advantage of to do a favor to them and at the same time I do a culture myself :biggrin:

the dimensional tolerance problem in my opinion should be clarified if the print defect occurs on a single random piece or if it repeats on the totality of the prints .
In the first case I think it is attributable to electronic/mechanical components that obviously has no costs equivalent to the most blasoned .
in the second case, however, I think it is attributable precisely to a failure of the hardware that pilots the machine;
the customer who measures the printed and then contests it is another shiren topic that we both know very well, but sometimes it is not print defect.... You know what?

I found this link where it seems that the printers in question are Chinese rimarcato

hi, I fully give reason to ip, the mass diffusion of the cheap 3d printers that is bullyingly advancing is a good on the one hand because it makes known the fantastic possibilities of additive production even to those who are not properly in the industry but on the other it seems that all problems can be solved with machines of 1000-3000 €.
Unfortunately it is not so, or fortunately for those who like us do it of business.
I have had a way to test an economic printer and I must say that it can be useful if I use it internally to understand a little better what will be the shape of the piece that I am drawing compared to the only display on the screen, but the uses practically stop there.
reproducibility is scandalous, at least in a mechanical environment (millimeter variations on the geometry of the piece), as well as the mechanical characteristics of the object.
the great difference more than in the material used (classically abs, the pla is more polished but more fragile) lies in the adherence between the layers. a professional machine works with hot room (70-80 °c) while economic machines are at room temperature.
another aspect lies in the calibration of axes, for economic machines it is a work to do manually: z axis calibration should be done using a sheet of printer paper as a space between the nozzle and the top (the sheet is usually 0.1 mm). the precision of the calibration is therefore quite approximate and the error is amplified greater is the height of the piece to be built.
professional machines self-balancing all axes before starting each processing.
I hope I've been helpful.

hello faust and hello to all,
in my company a few months ago was purchased this stamapante the hamlet hp3dx100 to make some details plastic.
I got the burden (or honor..) to understand how it worked and especially how to get the best quality on the press. I leave you these considerations of mine, premitting that this is my first experience in the field, even if today it took me a lot of this world.
the printer does not lend itself to a professional use, but more at an amateur and demonstrative level, the print precisions are around the millimeter, then get small walls or forellini (for example) is difficult and the result is aleatory. I have documented myself to understand the meaning of all the parameters that come into play during the press, but the result does not change. for massive and not particularly complicated objects you get a good result.
the software to kit is, in my opinion, the biggest flaw of the product, it does not allow you to do anything except to generate the list in g-code, while with others you can see the paths that will make the extruder during the printing and other useful settings.. .
As for the cubexduo, I never heard of it, I gave a peek on the internet, it seems to me a somewhat more beautiful product of the village even if my impression, watching video on youtube, is that the quality of the print is very similar.
even at a distance of time from your post...stero you were useful.
Hi.

to generate the g-code I found myself well with kisslicer, allows to make slicing allowing to check how the layer construction will come by layer and allows to set a whole set of parameters related to the construction: % filling and relative form, type of raft (back base), type of supports, ...
If you can bypass machine software and directly provide g-code I suggest you do some tests, kisslicer is one of the software but there are also others.
