B2Pi:

I was born in a Log Cabin, with my trusty six gun by my side....

Retired software guy (about 10 years in Silicon Valley, 10 years on the street, and 10 in Academia/Medical). I've a woodshop in my basement where I dream dreams of 7th grade shop (and make sawdust, lots of it). I started playing with CNC routers a while ago, and that leads to 3d printing, thus bringing me here.

==Current Plans==

I no longer have a desire to take over the world. I am preparing to build a Prusa i3 3D printer.

I almost pulled the trigger on buying an i3x kit from [https://shop.diytechshop.com/?q=content/i3x-prusa-i3-style DIY Tech Shop]. However, the aluminum frame is only 1/8" thick, and I wanted to get the full experience of building something close to my own. Nevertheless, that kit goes for about $480.00 for the full kit. This page is an exploration of the alternative. I may still do that (see notes on [[#Frame|Frame ]]).

Bulk purchasing always helps (especially when importing pieces from China), so DIY Tech Shop has an advantage from the start. However, I plan to print the appropriate pieces at the space.

===Features===

I may be getting way to complex from the very beginning, and I'm not sure if all of these pieces will properly fit together, but this is my current feature set:

* Standard Prusa i3
* Control
** RAMPS v1.4
** MicroSD Card
** LCD with Jog wheel control
* Hotend
** E3D
* Extruder
** Greg's Wade Reloaded

===Subcomponents===
====Frame====

[[File:Prusa3-Frame-Small.png|frame]]
I've seen very few printers built with the box style frame, mostly because the laser cut or aluminum frames look more 'professional'. It seems to be acknwledged that the box frame is stiffer. For me, it's significantly cheaper, as I have a decent supply of furniture grade 1/2" ply. Thus, the frame will look something like that shown (The Sketchup file for the frame is available [[Media:Prusa3-Frame.skp|here]]).

If I abandon the idea of self sourcing and go with the kit mentioned above, I will at least add plywood gussets to the aluminum frame for stiffness.

Note that no print bed is shown. I believe that the design calls for a 12mm thick piece of material, and is fairly intolerant of changes to that dimension. I would not think that plywood would be ideal for this, and will probably start with a piece of MDF with a 1/4" sheet of lexan on top. As with all else here, I am more than open to voices of reason.

==== Mechanicals ====

The mechanicals include the smooth rods, in addition to some linear and idler bearings. There's a kit with all required (I hope) on ebay for $120.

Additionally, drive is taken care of by GT2 belts and pulleys. These are widely available for less than 15 for the set.

Note that expansion of the print area (in terms of X and Y) is primarily done by using longer smooth rods and GT2 belts.

==== Control====
I've quickly gotten a bit familiar with the [[UltiMaker]], so I'd like to replicate that control setup in function, if not in components.

The RAMPS v1.4 is reasonably priced, bog standard, quite expandable, making it an easy choice.

The MicroSD card with the LCD and Jogwheel is a comfortable way of working.

A kit containing the an Arduino Mega clone, the RAMPS shield, 5 stepper drivers, 6 (mechanical) limit switches, a 4 line LCD with SD Card slot and jog wheel, as well as a fan, cables, thermistors, and a heatbed and a couple of spare pulleys (?) is available on eBay for $150.

==== Motors ====

The Prusa i3 uses 4 76 oz-in NEMA 17 stepper motors. The extruder requires another. Sets of 5 are available for $70

==== Extruder ====

Having selected the [http://www.thingiverse.com/thing:18379 Greg's Wade reloaded - Guidler, Tilt Screws, Fishbone Gears extruder], Ultibots has the [http://www.ultibots.com/gregs-wade-extruder-hardware-kit Greg's Wade Extruder Hardware Kit] available for $23.

==== Hotend ====

Finally, the [http://www.filastruder.com/products/all-metal-e3d-hotend All-metal E3D (v5) Hotend] has people raving, so... available for $70. A bowden version is available for $17 more.

=== Summary ===

I believe that that's all the parts needed. Some Kapton tape, a pc power supply, filament (beyond that needed for parts printing) and, as mentioned, a print bed will be required, but I don't see that as being hard to source locally and cheaply.

The number then, by my figure, comes out to $435. Were it not for the fact that the functionality is enhanced over the aforementioned kit, I don't think it would be worth it. As it is, I believe I'll wait for the voices of reason.
