    Nederlandse leveranciers filament

    in Nederlands

    Posted

    Ik kom steeds weer nieuwe filemant leveranciers tegen. Vraag me af wie wat al uitgeprobeerd heeft:

    Hestay – http://www.hestay.nl/nylon-filament-glas-helder.html en is 3.00 mm ook te gebruiken (ipv 2.85)?

    Prometheus – http://prometheusfilament.nl/product-categorie/filament/175285-specials/nylon/nylon-2-85mm/

    En 123-print doet er nu ook al aan.

    Ook kom ik ineens HIPS als materiaal tegen. Iemand al mee gewerkt?

    En tot slot: ervaringen met UM2 en flexibel filament?

    Colorfabb bamboo settings

    in Materials & profiles

    Posted

    Bamboo. Hopeless. Colorfab was so nice to help with the best settings as well as with a new filament to compensate for all the trouble.

    Bad luck, second wider nozzle is also ruined. Bamboo just does not work. Printing top layers is where it all goes wrong. Tried different temps, different speeds, different nozzles. The stuff burns inside the nozzle. Then it's game over.

    DO NOT BUY BAMBOO!

    Cura 15.06 Pause at height

    Nice try. Found a third Plugins folder in the new Cura:

    Contents -> Resources -> Uranium -> Plugins

    So Cura has three plugin folders. And the fun of it: still no go.

    Maybe add a fourth plugin folder?

    C'mon guys. Make some documentation on Cura. And i do not mean technical documentation, but useable documentation. This really sucks.

    Glue stick

    in Official news

    Posted

    Really. From prersonal experience...

    You buy a $2000 Ultimaker 3D printer with heated bed and all. But results suck if you do not use a generic $1 glue stick on the glass plate.

    The glue heats up and sticks like hell. You have to let it cool down to get the object from the glass plate.

    Any glue stick will do. Now and then clean the glass with a spunge and warm water.

    Some questions about the new Cura

    in UltiMaker Cura

    I use the old and new Cura side by side. Got a few questions on the new Cura, which is beautiful by the way.

    1. How / where can i save the print profile? Cannot find it in the menu's.

    2. For the old Cura i used the plugin Pause at height. Is there something like that for the new Cura?

    I like the concentric bottom/top pattern. Much better result for horizontal surfaces.

    Thanks.

    Bamboofill & Laybrick underextrusion issues

    in UltiMaker 3D printers

    The Bamboo adventure has two results now.

    The first one is that my filament feeder (don't know the proper name for it) that pushes the filament up on the back of the machine, does not work properly anymore. Probably has remains of the bamboo on the wheel or something.

    Second is the reply from Colorfabb:

     

    Thanks for contacting us with your issues, I wish you contacted us sooner. Yes the special filaments are more tricky to work with, but not impossible with some adjustments to your print settings and maybe strategy.

    Which machine did you use? What settings did you try?

    As mentioned in the Ultimaker forum thread, one of the tricks is to start out with layerheights of 0.2mm (max 0.27 for 0.4mm nozzle). Combined with a speed of 40/50 mm/s it'll ensure a decent flow of material and an acceptable residence time for the filament inside the hot-end. When printing at lower layerheights the speed needs to increase quite a lot, else the residence time is too long and the polymer and fiber can degrade.

    If you're looking to do a lot of printing with either woodFill of bambooFill, because you need it for a smal series production, then it's a good idea to install an nozzle with slightly bigger nozzle orifice. 0.5 to 0.8mm would be good. This also increases the flow, and therefore decreases the residence time of the filament inside the hot-end.

    A bit disappointing it is. They better add this info to their webpage about the bamboo. The settings mentioned did really not work. So now i have to order different nozzles for the bamboo.

    I will order these wider nozzles and will reply my results here. Not giving in that easy.

    I just finished cleaning. Removed the filament hoze (or whatever fancy name it has), heated up the BBQ and pushed good filamen through with force by hand from the top of the extruder. It took some time for all the dirt to come out.

    For me woodfill went fine and even copper went great with a bit more speed.

    Hope Colorfabb will come with settings that work.

    Maybe Cura can get a Results-plugin.

    After a print with certain settings, you use the plugin to evaluate the printing results and used material and objectives you had with making this print. Off course the evaluation Q&A have to be quantifiable. The plugin sends these results back to UM for processing into presets.

    Thoughts about the new Cura

    in UltiMaker Cura

    Posted · Edited by Guest

    Ulti Event Utrecht, november 15 2015. We got an in-depth presentation on the new Cura. A new architecture with basically the same functionality, but presented in a different way and with way more settings for the advanced users. These settings are somehow hidden, so new and less experienced users are not scared off.

    The four simple settings are now replaced by a slider with actually one hundred simple settings. Which is nice if time is an issue in your printing, as time is the parameter in this slider.

    Then there are the plugins. Cura is now fully built around the concept of plugins. So also basic functionality like importing .STL files is now done by plugins. This means that programmers can really add or change things to the core functionality of Cura, while plugins in the current version are only for post processing the gCode. Off course building these plugins is not for dummies. You have to know your way in Python and in the structures of Cura.

    Nice

    The nice thing about the new plugin architecture is that for instance suppliers like Colorfabb can make plugins especially for their own filament. So if you want to print with copper filament, the plugin manages all the settings, even the obscure ones that you normally would not tweak  by yourself.

    Off course the new Cura is an ongoing process, so things it cannot do today, might be possible tomorrow. The new architecture makes that possible. Chapeau for that.

    Better

    However two aspects can better be done today then tomorrow, because they are too much built with "nerds" in mind than with end users. Let us not forget that the people who buy Ultimaker (instead of Velleman or other diy-brands) buy Ultimaker (especially UM2) because it is plug and play.

    Think of users like inventors and artists who use the UM2 as a mean to reach a goal, and who do not have 3D-printing itself as a goal or hobby. Those users are still left in the shade of obscure and hard-to-understand settings of the current Advanced tab.

    Time, Solidity and Precision

    The first thing is the time slider. It only influences time aspects of the print, but does not show the influence it has on the printed results. There are two more aspects of printing that could easily be integrated in this new approach:

    • solidity of the printed object
    • the finish of the object, or precision

    One could think of a  set of three sliders in stead of one, with accessible names like Speed, Precision and Solidity.

    These sliders influence different settings, like infill (solidity and time), layer height (time, precision), shell thickness (time, solidity), print speed( time, precision) and more. By tinkering with the sliders new as well as advanced users can influence the end results and see what it does with time. They can also simply shift the time slider like it is now.

    Plugins and Post Processing Scripts

    The second thing is the phenomenon of Plugins. The makers entangled two totally different actions into one name: plugins.

    On the one hand, the new way of working with plugins is the domain of developers and suppliers and die-hard hobbyists in 3D-printing. This new approach is really a giant step forwards with Cura. It all has to do with the functionality of Cura.

    On the other hand, it's the old way of working with plugins, which has nothing to do with the functionality of Cura but is all about post processing the gCode. This is about the printing itself.

    This post processing should be given another name and another place in the new Cura. Programming these Post Processing Scripts (PPS) should also be made as simple as possible. These PPS's start their jobs when the user pushes the Print button. They have no influence on the functionality of Cura. By mixing these things together, Cura gets more "nerdy" than it should be.

    Changing markets

    3D printing is becoming more and more the domain of end-users, of people who will use the 3D printer like they use their laser or ink-jet. In less then five years many house holds will have a 3D printer for hobbies other than 3D printing it self. A major USP for UM2 is careless printing. Cura should also fit with that USP, by focussing more on the end results of the printed object.
