Printables.Com Download to PrusaSlicer Integration Instructions

Today Prusa made their latest alpha release of PrusaSlicer available on github: 2.6.0-alpha2. (Make sure you understand what alpha testing is before downloading/using this software. An alpha or release of a software package intends to do something particular, and mostly does so, yet isn’t guaranteed to do so fully. You are testing out an early version of this software, if you find a bug, report it.)

There are many game-changing features in this release, but in particular, this post provides step-by-step instructions on how to get the “auto downloading from printables.com directly into PrusaSlicer software”.

  • Enable “Show PrusaSlicer button” in your profile while logged into printables.com.
    Click the avatar icon (upper right corner), then chose the first line item (your user name), then scroll down next to the bold title “Info“, and click on “Edit your profile link”. When the modal window appears, scroll down to the checkboxes section and enable the checkbox for “Show PrusaSlicer button”, then click “Save” at the top of the window.
  • Enable download option in PrusaSlicer software.
    In the menu, select Configuration -> Preferences (or Ctrl-P), then select the Other tab. Click the checkbox to “Allow downloads from Printables.com”, then choose “OK”.

These changes should make it so you see the the PrusaSlicer icon next to the download button while viewing a model’s “Files” list.

Select the PrusaSlicer icon next to the file you want to test, confirm (twice) that you want to allow the download integration, and everything should be working.

I’ve tested this on a Windows 10 PC using Chrome, Firefox, and Edge successfully with PrusaSlicer 2.6.0-alpha2.

Feel free to try out the integration on some of my models on printables.com.

My 3-D Story

I have been doing 3-D modeling and 3-D printing since 2011.

I started out with a RepRapPro Mendel TriColour that I built from a parts kit and upgraded several times. This was a great printer, but was frankly borderline experimental. Everything had to be frequently adjusted by hand and successful prints were occasional (maybe 50% at its best.)

My second printer was a cousin to the first, a Prusa I3 MK3 (now an S) built from a kit that I got in November 2018. The improvements from the first to second printer include: auto bed levelling, filament run-out detection, magnetic spring steel flexible print plate, Bondtech dual gear extrusion system, custom E3D V6 all-metal hot end and resume on power failure. Basically, it has improved every area that could have been considered weak or unreliable through iterative engineering. The printer has been an absolute workhorse (currently at 29 kilometers of filament extruded) and my print success rate is more like 98%. Don’t call it fool-proof (they’ll invent a better fool) but it is a solid, consistent performer.

Over the last twelve years I tried a variety of (mostly open source) slicers with varying degrees of success. SkeinForge, Slic3r, Repetier, Cura, KISSlicer, IceSL. Prusa forked Slic3r into PrusaSlicer which is currently the best, most integrated, and extensively developed slicer option available.

I’ve made extensive use of Blender, OpenSCAD, FreeCAD, and a variety of other open source, free, and for-pay, commercial software over the years to do design, object repair, object modifications, customizations.

3-D Printer Maintenance

Basic preventative maintenance will keep you printing problem-free. Periodically check and fix the following areas of your printer.

  • Vacuum up all the little pieces and parts of filament that drop off as the printer heats up, failed print debris, etc.
  • Dust your printer. Canned air will work fine. Blow out the fans, controller box.
  • Check the extruder body internals for filament crumbs, buildup. Do a cold pull of filament.
  • Clean your linear bearings and load them with grease. If possible, do this during initial printer build, or the next time you do a major overhaul.
  • Check for wiring fraying or chafing.
  • Check X, Y, Z round rods for any marring or flatspotting (indicating not enough lubrication) or other unusual wear. Do all the axes run smooth and straight?
  • If your print quality is consistently low and no settings seem to improve it: it’s probably time to change your nozzle. They are relatively easy to change.

Check your printer’s vendor’s documentation or website for specific maintenance suggestions.

Best 3-D Object Repositories (2022)

Printables.com (formerly PrusaPrinters.org) – the new object repository database for users of all 3-D printers. [.stl, .3mf, .gcode]

STLFinder – Indexes .stl files from a variety of sources on the internet: a 3-D object search engine.

Cults3D – free/pay object repository.

Thangs.com – Free 3-D model community with geometric searching.

Thingiverse.com – formerly the leader, still a large collection, but site maintenance has gradually declined, owners have added advertisements to site.

Fall has arrived!

We’ve recently printed these colorful pumpkins for a local Montessori school, what can we make for you?

The pumpkins are approximately 6 inches in diameter and about 5 inches in total height.

Help! My printer is broken

Blob of Death™, printer making weird clicking noises, parts dangling where they shouldn’t?

While using your 3-D printer, you may find that you come across a print-stopping situation. You are missing a piece, something isn’t working right, a part broke, etc. I’d always recommend exploring your vendor’s support offerings. They will frequently walk you through the issue and/or send replacement parts. But there are times when you just need a part re-printed (now that your printer is broken…) and you’re stuck in a catch-22: You can’t fix your broken printer problem with a broken printer.

If you have the .STL files for the piece or pieces you need, we’re always willing to help a fellow 3-D print enthusiast out of a jam. Just contact us with the details and we’ll see what we can do to help you get what you need.

How does 3-D Printing work?

The first step of 3-D printing something out of plastic is to define or get a 3-D model of the object you would like to print. To define the object you would use 3-D CAD (Computer-aided Design/Drafting) software like OpenSCAD, Autodesk Fusion 360, SketchUp, or OnShape that allow you to design your object and export the result as an .STL file. Alternately, you can search an find a part that has already been designe that also meets your needs. There a numerous 3-D model repositories and index sites online where you can download (free and paid) models to print.

Once you have your desired object defined, it will be loaded into software called a slicer (we use PrusaSlicer) that will break the 3-D object into a series of discrete layers and generate the step-by-step instructions for the 3-D printer to follow to create the object. There are many variables (layer height, perimeters, infill type, infill density) and configurables (support, rafts, brims) that can be modified in the slicer to get the exact print result you want. The output of the slicer software is a .gcode file containing all the instructions.

This .gcode is then loaded onto the 3-D printer along with the desired filament and the printer is given the instruction to start printing. The printer will heat up the bed and nozzle, the step through the instructions (gcode) created by the slicer. Depending on the size of the object, the layer height, density of infill the printing of your object can take anywhere from tens of minutes to tens of hours or even multiple days.

Once the print is finished the printer will cool down and the print will be removed from the print bed. Any necessary post processing (removing supports, sanding surfaces, finishing, painting) would then be performed. This process ends with a 3-D plastic model of the object you designed or selected.

While the capabilities of 3-D printers continue to increase and prices continue to decrease, we realize that not everyone wants to do every step of this process. We can help by performing any or every step of this process for you, or we can assist you in any area where you need help.
