RepRap: Upgrades!

This year I started feeling like I was falling behind with the opensource 3d printing movement, so I made the time to upgrade my printer. I started by finally installing a new heated bed. Before now I was still printing PLA on blue tape. Now I'm printing PLA on heated glass. Here is a before and after:




 I followed Nophead's lead with simplifying the y axis by using a few linear bearings.

While I was at it I also upgraded my electronics! I was pretty happy to get away from prototyping breadboards by upgrading to RAMPS. These pictures say it all...

Before:




After:



Finally, I upgraded my extruder. The old extruder was my own design that was still running strong after over a year of use, but it was big and bulky, taking up to 10 minutes to heat up. It also pushed 3mm filament through a .5mm hole. The new MakerGear extruder only takes a few minutes to heat up and pushes 1.75mm filament through a .25mm hole. Here is a before and after:



Special thanks to the authors of the following things on thingiverse to add finishing touches to my printer:

 I am very happy with my printer and can't wait to start working on my DogBot again!

  6. heir daily activities are so beneficial and spirited. It would be very relaxing to be in silence for the majority of each day, it gives you a chance to absorb your surroundings. The food portion stuck out to me because I never stop to think about the growth process of what i’m eating and marvel of natures creations. Gifts Australia

With a population of 133,412 residents and an estimated 50,000 workers in an area of 1.92 square kilometers, the city is one of the world's most densely populated cities. Male is situated on the southernmost tip of the North Male' Atoll (Kaafu Atoll), directly across from the Maldives International Airport. Male Maldives is a fantastic spot to visit for a short time. It houses many of the country's most important icons and landmarks. Among them, one of the most well-known among visitors is: (Old friday mosque, Stingray point, Fish -market, Artificial beach, Victory monument, Male Square, Museum, Souvenir Street etc...). During peak hours, the streets are very narrow and congested.male city
