So, this step is optional, and whether or not you want to be able to control all your fans on your printer or not. To do this we will install the RAMPS 1.4 RRD Fan Extender – read on! On this printer, we have hooked up a hotend cooling fan (NOT the part cooling fan) which … Read more
Tag archive for all things to do with the P3Steel Prusa i3 3D Printer, and mine. The P3Steel is a remix of Twelvepro’s redesign of Josef Prusa’s i3.
A little info about the P3Steel Prusa i3 3D Printer:
Leonardo – the prototype P3Steel printer – was designed and built by Irobri in April 2013, after attending a local Maker show in Zaragoza, Spain. The main frame structure, built from laser-cut 3mm steel, is extremely strong and simple to assemble, and eliminates the need for several printed parts due to the use of steel parts instead of threaded rods for the “Y” subframe (as in the original Prusa i3 and many of its variants).
- Steel as a building material has several advantages over e.g. aluminum
- Steel is one of the least expensive building materials available – structural steel is 10 times cheaper than aluminum.
- Laser cutting steel is easier and cheaper than cutting aluminum.
- Steel is stronger than aluminum.
- Steel is 3 times heavier than aluminum, although this could be considered both an advantage and a disadvantage, in the sense that a heavier frame does not tend to vibrate as much as a lighter frame. Also, if we consider the total weight of the printer, the difference between an aluminum frame and a comparable steel frame is not that much (around 2.5kg extra).
- Structural (carbon) steel requires painting or galvanizing for protection against corrosion. Stainless steel, of course, does not require painting.
The P3Steel design is for 3mm thick steel and with lots of carvings to reduce weight. All square holes and tabs have special rounded corners for accommodating corresponding parts and give a very good fit between parts.
The design has slots for M3 nuts in the places where the screws fit so no threading is required.
Improvements over the standard Prusa i3
- Stronger frame due to the use of structural steel.
- Solves the frame flexing thanks to its reinforcement squares.
- Simplifies the construction, eliminating the complex subframe of threaded rods in the Y-axis.
- Once assembled, everything is in place, no adjustments needed.
- Eliminates the need for several printed parts.
- The steel mounts for motors and rods are much stronger than their plastic counterparts.
- The only two threaded rods needed are the ones for the Z-axis (5mm).
- Uses shorter smooth rods lowering the build costs.
- Once assembled, it forms a compact, solid structural unit that can be transported as a block.
Controlling and monitoring your 3D printer can be done with your PC via the USB connection, using a dedicated Linux box and web connection over LAN/WiFi such as Octoprint or Astrobox, or with a dedicated LCD Control panel (and SD card slot).
The RAMPS board is going to get very cramps, very quickly. It’s well designed and thought out in terms of layout, but as you add more and more connections to it, it’s going to get hidden beneath a nest of wires, connections, crimps and fans – say goodbye to your lovely clean clear red board!
Printing and assembly of the main hotend assembly – the hotend mount, cooling fan ducts and all hardware needed and connecting wiring.
Now that we have power to our RAMPS board – lets take care of it a little, and add in some active cooling to the board with a RAMPS Cooling Fan.
Behold the finished power supply cover printed in orange. I would show you the timelapse, but it looked so bad it looked like it was filmed in the Bat Cave!
Not much to show here. But the TL;DR is this post shows a couple of videos and shots of the extruder and mount.
When building a 3D printer, there are lots of options you can go with for a build platform, and whether to have it heated or not. I will not go into all of them, but simply state what I am going to use compared to Toolson’s designs.
Brilliant original design of an Amazon Echo Dot V2 wall mount by halcyon on Thingiverse. I have had a lot of people ask for this to be printed on 3D Hubs and from their feedback I have updated it with some of my amends.
To support the print bed from the y-axis and the bed frame Prusa 3D printers use bolts, washers and nuts on each corner with a spring for tension. Toolson’s edition of the P3Steel does away with these springs and opts for a novel (genius) solution of using silicone dampeners.
