Sweet! Really good quality as well, what printer?

Filemon: It is a heavily modified MakerBot Replicator 2. i have added a heated bed and all aluminum carriages as well as enclosing it with the stock 2X Side panels. The Replicator 2 is “ok” stock but with a few hundred in upgrades it now prints ABS, Nylon, and PLA equally well and delivers almost 100% repeatable results.

The quality is really impressive! Can’t help but wonder if you pimped that nice camera in the back with anything 3D printing?

There are some things that should not be adorned with plastic.

However i did print a lens cap once when i lost one so as to protect it while i order a new one. Also i have printed some film cases and filter cases.

The pen cup in the background was however printed!

Awesome! I would love to see some pictures of your upgrades! I was actually quite curious how you achieved such quality repeatedly with the makerbots. I knew you had to do something! The Marvins look awesome and I can’t wait to give them out. Colors came out great!

boydconnor · 2015-10-18T15:55:38.000Z

I second that! I’m really curious what you did to achieve such high print quality. Truly amazing results.

I don’t have access to the printer right now as i am at work but the key upgrades are these:

BC Tech: Heated Build Plate - Removable glass plate and aluminum heated bed upgrade

Aluminum Arm Stiffeners (Replicator 1 2 2X Flashforge Wanhao) – Performance 3-d - Aluminum arm stiffeners

Upgrade: Aluminum Idler kit for MakerBot Replicator 2 X-End - 3D Printing Blog - X idler replacement with aluminum/ball bering idler. (plastic on metal is no way to run a precision machine. WTF was Makerbot thinking!)

shop.raffle.ch - Aluminium x-ends.

shop.raffle.ch - Aluminum carriage for the extruder

i also have printed soft vibration absorbing feet for it in Ninjaflex. cut down on the operating sound of the printer by at least half!

Endless other upgrades to the system that i have printed.

Honestly these were printed at 200 micron layer height at 120mm/s and i printed 10 in about 1.5 hours. This printer is capable of much much higher resolution if it is needed albeit at a slower print speed. With all the aluminum upgrades vibration and flex is almost eliminated and 50 micron layer height works well but is as slow as christmas. Even at 120mm/s it takes an eternity to turn out a print. I prefer the 100 micron or 200 micron layer height as i have learned to love the layers as proof that my object was printed. At 50mm it is almost perfect and to me that takes away from the awesomeness of being able to show people that something was actually printed on a printer.
