3d printer precise on polyethylene, advice?

[yordanrhapsody]

Hello everyone, I am new to the forum, I need to search and possibly buy a 3d printer that allows me to print polyethylene of small devices

devices must have great precision

I had tried time ago a printer that had produced grooves on the edge in correspondence of the various levels of printing, of course I would like to reduce the phenomenon to the minimum

would you give me suggestions on the models available? I'm willing to self-build it, but I think I understand that those opensources don't have the level of precision I require.

Can we make it?

hi yordan, I am the owner of the ipdesign and for a few weeks I have been a dealer of the famous makerbot .
I have the first printers in delivery in a few days,
as budget we are within the amount you have available,
can print in abs , pla , flexible and being born as an opensource project if you have a polyethylene wire (which I think is comparable to the flexible rubber ) you can think of calibrating the print parameters for the material in question .
but to prevent this response from becoming an advertising advert I refer you to the relevant site of the American mother house .

Of course we are talking about minimum layers 0.10; if you need even smaller doubt you can find at those figures more precise stuff.
you should move to professional printers where the numbers in play have a minimum x10 multiplier.

if you need to send a mp

hi, are davide ardizzoia and produce professional 3d printers in Italy (www.3ntr.net).
if by polyethylene you mean pet (polyethylene tephthalate), the filament is available from different sources.
if you mean hdpe or ldpe... I think you can't find anything.

Why do you have to use polyethylene?

thanks to both for the answers, what I need is good precision (I would say that 0.1mm can suffice, but is precision on all three axes? or how do I read elsewhere only for the z axis while x and y less?), ldpe printing and if possible a certain speed (what we have to print are small products of size contained in a cube of 2cm on the side)

small printing lesson 3d :biggrin:
when 3d printers talk about layer 0.10/0.20/0.30 etc. means the thickness z of the material pass that the printer deposits.
in essence your object in order to be "printed" is first dissected in many horizontal "fettes" one above the other; these "feets" have a thickness of 0.10/0.20/0.30 etc.
each slice is then "designed" in its shape using as "penna" the nozzle or the nozzle that says you want to extrude a filament that will follow a predetermined design.
the extruded wire obviously has on the edges a rounded pattern that overlaps leave a wall "cappetta".
the greater this layer and the more this processing will be visible.
all this to say that the "precision" with the layer should not be confused.
the precision of a printer is the ability to replicate objects with dimensions as close to the original 3d model and above all replicate a number always identically.
the friend David, whom I greet, will agree with me in affirming that the precision in a printer is influenced by a myriad of factors, first of all the components, but also its mechanical structure and above all by what is at the base of everything and that is the goodness of the firmware of the machines and its electronics where the real job of setting from whom you provide it.
therefore only a wise mix of these things makes you have an excellent tool or a scrap .

thinking of self-constructirsela has the advantage of reducing costs, but the disadvantage that usually known of the communities of the "makers" to almost never know where to put hands to correct a problem that inevitably arises at the first prints. and then think about getting to a great result in a short time is pure utopia.

to conclude, if you need a printer "ready to use" entrusted to those printers marketing them; evaluates the costs, characteristics, assistance and above all the origin (I would avoid the Chinese) . made a first scramble made to make a piece from who the printer has it or better yet to see one in operation . many doubts can be escaped from the technician of turn .
if you want it "made to measure" then start studying and attending the world of repraps, and makers in general.

Good adventure:36_1_13:

0) the mechanical accuracy of a printer is 40% of the problem. to be able to accurately direct the position of the nozzle (x-y) and the printing plan (z) is good and right. Unfortunately, 60% of the problems (imho) arise from irregularities of plastic material. starting from the percentage of moisture absorbed (which is given during the printing in the form of steam, which reflames, altering the size of the extrusion) to reach the actual chemical composition of the product (due to both discontinuity in the process of extrusion, and to discontinuity in the quality of the polymer)

1) at the moment I do not know where to find ldpe done decently, since you need very precise prints.

(2) omissis

3) imho you can get what you want, but not in ldpe. much easier (wide choice of suppliers) in polyamide.
