PLA Filament reviews
- Nice review of many filaments PLA: http://3dprintingindustry.com/2015/01/21/pla-best-3d-printing-ask-3d-matter/
- Compare types of filament: https://www.matterhackers.com/3d-printer-filament-compare and http://quantum3dprinting.com/3d-printing-research/
place, url, type, cost, did it work? (place in order of descending price)
- Makerbot, http://store.makerbot.com/filament, PLA $48/kg, good filament but overpriced
- Ultimachine, https://ultimachine.com/, pla/abs, $44/kg, good high quality filament no strings, shiny
- Lulzbot, https://www.lulzbot.com/catalog/pla, PLA $43/kg, good quality no problems (also ninjaflex $60/0.75kg is awesome)
- Matterhackers, http://www.matterhackers.com/3d-printer-filament-compare, PLA $31/kg, good filament -- for smaller rolls can't print with the material at end of roll
- Zeni Kinetic, http://zenikinetic.com/filament/, pla $30/kg, duller colors some strings but good for most applications
- Push Plastic, http://pushplastic.com/, $29/kg w/free shipping, many colors and plastics to choose from. Colors are very vibrant. Prints very well. Made in the USA.
- 3D Solutech Through Amazon, http://www.amazon.com/gp/product/B00MB32T4O/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1.html, PLA, $26 -Good Filimanet however slight stringy difficulties due to being translucent filament.
- Hatchbox, http://www.amazon.com/HATCHBOX-1-75mm-3D-Printer-Filament/dp/B00J0GPC80/ref=sr_1_1?ie=UTF8&qid=1414676593&sr=8-1&keywords=blue+pla, $23.00/kg + amazon prime shipping, This filiment prints excellently, is completely opaque and is spooled very well. Highly Recommend
- Foxsmart, http://www.foxsmart.club/3d/filament.html, pla, $20/kg, I used white filament and it is printing well. The cartridge is a little bigger and does not fit standard spool holder.
- Jet, PLA , http://www.amazon.com/gp/product/B00815S5CG/ref=ox_ya_os_product_refresh_T1, $19.99/kg, It prints very well at 215 degrees and is a slightly translucent purple(its a pinkish purple). Spool is much taller than other brands

- Great comparison of flexible filaments 
Other commercial filaments
- bambooFill combines recycled bamboo fibers 20% with premium colorFabb PLA 80% to create natural looking, light-weight 3D printed objects.
- bronzeFill bronzeFill contains 80% finely ground bronze and 20% premium colorFabb PLA allowing heavy 3D printed objects that can be polished or oxidized to achieve the desired finish.
- copperFill copperFill contains 80% finely ground copper powder and 20% premium colorFabb PLA, and printed objects have great post-processing potential allowing heavy 3D printed objects that can be polished or oxidized to achieve the desired finish.
- woodFill combines recycled wood fibers 30% with premium colorFabb PLA 70% to create natural looking, light-weight 3D printed objects.
- copperFill Filamet Copper filament, 88.5% Copper, up to 99% copper after post processing. Expensive. I noticed it's also very brittle and the filament sample broke in half when I tried to wrap it around a spool. Also found a lump of filament that i had to break off which would never have gone through the extruder. Must print slowwwwwwly. First print impression: prints surprisingly well and looks super nice. Lastly, this filament does not go a long way. A 15g print of pla = ~50g of this.

- USING the SCAD render_plate is for production purposes and won't be of much value to the average user. render_part is the one to use for individual parts. Make sure you're pulling the code from the athenaII repo (https://github.com/phidiasllc/athenaII). Also be sure you're using the latest version of scad-libraries (https://github.com/phidiasllc/scad_libraries).

Per our campus network security officer, you will have to use VeraCrypt (https://www.veracrypt.fr/). Students will have to use the portable version on either a USB flash drive or installed on their laptop. It cannot be installed on our Windows lab systems.
Portable version can be found on this page (second version under Windows) and should be able to be run from anywhere (H drive, USB, etc): https://www.veracrypt.fr/en/Downloads.html
There are no dimensions on the donut/base because we use a CNC router to cut them. I use LibreCAD (https://librecad.org/) for that sort of designing. It has an easy-to-use dimensions tool or a point-to-point tape measure tool that can extract the dimensions. We do indeed cut both the donut and the base out of a single piece of 12mm Baltic Birch plywood. Baltic Birch is the best choice as it is extremely stable and has more plies than normal plywood. It also is less tend to expand and contract with humidity and temperature fluctuations. That stability comes at a cost, however.
