RioRand 5 x A4988 motor driver with heatsink,3D printer RepRap Prusa, Mendel

1.A4988 driver
This product is a carrier board or breakout board for Allegro’s A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection by Pololu; we therefore recommend careful reading of the A4988 datasheet before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 2 A output current per coil.

This 11x11x5mm heatsink, purchased for use with the pololu A4988 drivers, despite their tiny size they are still very large when placed on the driver, may require machining to fit on the Pololu drivers but if careful with soldering and it clears the SMD resistors I don’t see the need for any modification.

A Mans Face Was Reconstructed By Britsh Surgeons With 3D Printing

British Surgeons Reconstruct Man’s Face with 3D Printing After Accident


The application of 3D printing technology in the medical field is not new at all. For years now, people have been finding inventive ways to solve medical issues with unique 3D printing solutions. The use of prosthetics created using 3D printers is quite common for those in the know, even though the popularity of this use of the technology is gaining more publicity as the methods are refined and fine-tuned.

Recently, a team of British surgeons created replacement parts to restore the damaged portions of a road accident victim. The main thrust of this effort is to restore symmetry to the man’s face, using the parts created by the 3D printer. In order to achieve this, the surgeons created an image from the unaffected part of the biker’s face, allowing for a virtually perfect facial reconstruction using the exact replica.

The surgeons used an X-ray CT scan to create highly detailed three-dimensional images used to design the implants used by the maxillofacial surgeons.
