Good morning, everyone.

here in the company it seems there is the intention to buy a 3d printer to realize small items of jewelry and accessories for footwear.
was asked to me to provide an overview of costs and technologies and then to orientate towards the product that best suits our needs.

I press that I know at great lines the difficult types of work of these machines, but I am far from being a deep connoisseur.
So I ask you to illustrate the limits and characteristics of these systems.

as I said before we should make small pieces and not in large quantities.
Therefore large areas of work are not necessary.
more interested in the surface quality in order to save time in the various phases of manual finishing, the possibility of painting and ultimately the resistance (it could happen to have to literally bend an accessory to adapt it to the upper of a shoe, so the important thing is that you do not break).
 
thanks anyway for the iron answer.

Is there anyone who can give me any indication?
 
we have 2 printers:
a print abs but it's the same as the friend he wrote on.
the other is a printer we say of "sintergesso" i.e. prints a kind of chalk and then is impregnated with resins of various kinds.
changing materials you can also print materials that then you can " fold" type rubber.
we have for example realized some funnels that in the end were reversible, even seals of a certain thickness! ! !
if you're interested I had put a "sale" ad to this forum:http://www.cad3d.it/forum1/showthread.php?t=29634contact me for any request

Hi.

I had a zprint to try it some time ago and I have to admit I thought better. or I thought the pieces had a better finish and kept smaller details. But it may be misplaced or otherwise.

As for the abs I deduce that the type of machine is not able to meet the requirements listed before. Or not?

However, I would like to point out that we would prefer greater surface quality to the detriment of the mechanical resistance of the piece. until, at the limit, to give up any functional quality in order to have a very well finished piece.
 
I recently tried the proto with polyjet technique. I have to say that the quality is true good that on small pieces. I supported a networked society.
 
@sokak.
In fact our type of machine does not lend itself for this type of objects.
I agree with marcobes on the quality that in this case polyjet technology can offer. . .
but only in this, huh?! :tongue:

Hi.
 
I witnessed the presentations of the hp series that print in plastic and we did some tests with rhino.
I have to say that for mechanical prototypes it is really great, while the finish is a little crumbled. However, being rigid plastic, with a small paperwork you can easily remedy.
colors are obviously limited to the plastic sample of the machine but can print in a single working prototype solution also composed of several parts.
It's a little slow, but with a price on 12000 euros it's not even inadparable.

I have both fdm and polyjet and I would say that if for quality it is better the second for many others is the first, to give a more precise answer it takes more details.. .
 
Hi.
I own two different 3d printers, if you want, I can give you some disappointment about it.
I own an ultra-high volume envisiontec, liquid resin printer (dlp technology) and an objet (polijet technology)
I can also give you a few sample pieces so you can evaluate.
It seems to me that your needs are for medium volume parts and some flexibility features. Perhaps only an objet can satisfy these needs, including the change of material that is not something recently.
 
hi alpha can I ask you between the two technologies which is more convenient in the press? and you could give me the contact of the Italian dealer of the envision that I can't find.
to make architecture plastics what would you recommend?
Thank you.
p.s. compliments for the excellent site.
 
definitely the costs of envisiontec are very reduced. even if the materials in use (the resin) range from 225 to 255 euro per kilo. therefore the materials are among the most expensive in the industry but the consumption is contained. officially envisiontec in Italy is represented by vision-numerical italia. a cazzago (ve). However for architectural plastics these machines are not only not recommended but you just wouldn't be able to build buildings already assembled because you have to fill all the cavities with construction supports (which you wouldn't be able to remove) useless attempt to build single walls because this technology is such that it would not be so perfectly planar to be able to reassemble with the others. for these applications it is used the sintered nylon, technique decidedly cheaper but absolutely fit for plastics.it is enough to build the individual planes without the soles and then reassembly, all with extreme simplicity realized.

Very interesting!
this synthesized nylon, that you know, from which machines is used?
and the syntergesso, the zprinters, who tell me, this morning a retailer recommended it for architecture, in particular for the costs contained and the absence of supports.
Moreover, in another tread you talked about dealing with these prints with epoxy resin, for resistance.
I have no idea how this would work and if the final aesthetic quality of the model would improve or worsen, can you tell me where to find info about this procedure for pleasure?

I forgot the z-corp machines.
Of course I do. It is much better. this at least for two reasons: one piece coming out of the z-corp can remain as such as or treated with a relative resin that gives it a smooth appearance, a beautiful resistance to impacts and a general finish really aesthetic for plastics.poi the possibility to make the colored pieces is unique. in these cases of architecture can come back really useful. what not recently machines are really cheap and pieces cost even less than nylon sls.
Nylon sinters are mostly industrial machines with complex cooling and dust recycling plants. The chalk printers keep you in the office... .
 
I have no procedures, you have to consult your supplier, only he can give you advice.However any transparent resin that cares cold. let impregnate and then once hardened what exceeds the cards if anything.
 
Good morning
I have an envisiontec perfactory printer used to sell . the surface quality and the possibility to use different types of resin make it very versatile (the material change is very fast and does not require particular attention).
envisiontec technology is based on the photopolymerization of liquid resin and exploits the properties of dlp projectors to harden the layer.
