3d printing for outdoor use: what types of filament are most weather resistant?

  • 3d printing for outdoor use: what types of filament are most weather resistant? 1337joe

    I'd like to print modifications for my birdfeeder, both to patch over the hail damage from last summer and to try to deter the neighborhood squirrels. I have an FDM printer (and experience with nylon, ABS, and PLA, though don't restrict answers to those if there's something else that's better), what kind of filament would stand up best to daily exposure to sun, rain, snow, etc?

  • PET(G) is a strong contender. It is very strong and water-resistant, and as such is often used to make pop bottles.

    PLA has a reputation for being "biodegradable" and therefore it is often discouraged to use PLA outside and/or in contact with water. However, PLA only biodegrades under very specific conditions which it won't generally be exposed to so it can be used (though, as a harder and less flexible material it is more likely to be damaged by hail).

    ABS and Nylon are good choices as well. Basically, any plastic you have on hand will last for years, even in an outside application.

  • I'm looking at getting this printer, the da Vinci 1.0w 3D Printer, very soon as my first printer. Since this is an enclosed printer, from what I can tell from the pictures, and given that it is a PLA Printer (I'm assuming that is the filament it prints with), is a heated bed necessary? Especially since this printer doesn't have one? Or should I look at a ABS printer instead? I plan on printing 1:1 scale props.

  • printing with them. What I eventually noticed was that when the translucent filaments extrude, they come out in a noticeably thinner stream. Not sure why, I've tried increasing the hot end temperature and printing slower, but nothing seems to help. The effect seems to be that not enough filament comes out from the nozzle for the speed the head is printing at. I use cura for the slicer, and I've... comes off. Has anybody else seen this, where translucent filament extrudes thinner than solid colors? Any suggestions what to try to make it stick and print reliably? Thanks.

  • I not sure what this code does..... I recently bought a titan extruded that needs to be calibrated with my printer (417 microsteps http://wiki.e3d-online.com/wiki/Titan_Assembly#Firmware_Calibration). I am having a hard time understanding why they have D_Filament at 2.85 (my printer was made using 1.85mm filament) and why they used it twice in there equation. Also, what are the arc interpretations for? #ifdef ADVANCE #define EXTRUDER_ADVANCE_K .0 #define D_FILAMENT 2.85 #define STEPS_MM_E 836 #define EXTRUTION_AREA (0.25 * D_FILAMENT * D_FILAMENT * 3.14159) #define STEPS_PER_CUBIC_MM

  • The quality of the filament is frequently mentioned either as the source of an issue but also as the solution to a problem. I know that the way you use,store and protect your filament will greatly impact it's quality, especially overtime, but here I'm interested to understand what makes a brand new, out of the air-tight package, good or bad? What to look for when you buy filament (specs,chemical,weight,...)? What are some brands that are notoriously know to make "high quality" filament?

I am trying PLA with the same file, and it seems to work fine...I have just got a Monoprice Maker Select 3d printer (which is really just a Wanhao Duplicator i3). I want to print a model that came on the included SD card (1.gcode) with ABS filament. I first press "Preheat ABS" and wait for the display to show the correct temperatures, 245°C for the extruder and 90°C for the print bed. Then, I mount the SD card and select the file to print.
