Polylactic acid (PLA) is a bio-degradable polymer that can be produced from lactic acid, which can be fermented from crops such as maize. This makes it an ideal candidate for use in certain energy rich, cash poor areas of the world. It is harder then PTFE and melts at a lower temperature (around 180°C to 220°C), and a glass transition temperature between 60-65 °C, so is potentially a very useful material. It does exhibit higher friction than PTFE however which can make it difficult to extrude and more susceptible to extruder jams. For more details, see the Wikipedia entry on Polylactic acid For Chemists A note from wikipedia: The name "polylactic acid" is to be used with caution, not complying to standard nomenclatures (such as IUPAC) and potentially leading to ambiguity (PLA is not a polyacid (polyelectrolyte), but rather a polyester) Usage PLA is the ideal material for a Mendel RepRap.

PLA - White - Spool 2.3Kg - 3mm / PLAWHITESPOOL2300 / PLA 3mm / + ReprapWorld. PLA 3,00 mm : GRRF, German RepRap Foundation. Printplastic. Material PLA. Product Listing - Natural 3mm HighGrade PLA. This PLA is ordered by us to be a very high grade PLA for smooth easy printing with good results.
Guaranteed to flow throu the Nozzle with minimum effort and give good prints. We only have this PLA in NATURAL colour for the sake of not changeing this PLA:s quallity with any additives! We have a testprint with this quallity PLA in White 1.75 mm and it managed to print in staggering 1000 mm/sec, the fastest I heard about ever. The test was done by the most promising printer manufactorer we heard about, and we will during the summer start selling his printers here at Supply3DPLA. Shop - faberdashery. Category:Hot End. Arcol.hu - Products. Sanguinololu. Sanguinololu Release status: working Introduction Sanguinololu is a low-cost all-in-one electronics solution for Reprap and other CNC devices.
It features an onboard Sanguino clone using the ATMEGA644P though a ATMEGA1284 is easily dropped in. Its four axes are powered by Pololu pin compatible stepper drivers. The board features a developer friendly expansion port supporting I2C, SPI, UART, as well as a few ADC pins. The board is designed to be flexible in the user's power source availability, allowing for an ATX power supply to power the board, or the user can choose to install the voltage regulator kit for use with any power supply 7V-30V. Latest Updates Latest revision: Version 1.3a - Updated July 21, 2011 Version 1.3a has no software changes - the pin assignments remain the same and your 1.2+ compatible firmware should work here fine. Latest posts in the Forum Features Small design - board is 100mm x 50mm (4" x 2") - barely an inch longer than a business card! -- Logic supplied by USB bus. Sanguinololu - ReprapWorld. Sanguinololu, LCD and rotary encoder with switch. Having seen the PanelMax LCD and Encoder for RAMPS, I wanted to get a similar setup working on Sanguinololu. the first step was to get an ATmega 1284P working and load Marlin firmware which supports this sort of setup with minimal changes.
Wiring and Testing I intended to keep using the SDSL card reader (not much point in having a screen if you have to have you computer plugged in) which left very few pins unused on the microprocessor. Conveniently these are all together on the expansion header: The image is grabbed from the .brd eagle file - easier to show than on an actual board. There are 9 I/O pins free, one of which is within the SDSL plug footprint but is not used by SDSL. Adds up to 9, just enough! I connected the circuit up (quickly, I was impatient!) After connecting it up I loaded the Arduino 0023 IDE, and modified the "Hello world" example program from the LiquidCrystal library.
And define it as a 20x4 LCD lcd.begin(20, 4); Working with Marlin Configuration.h Line 34: Think3dprint3d gmail.
