SainSmart PLA works fantastically in my Makerbot Replicator 2.
I tried ordering plastic from Makerbot directly but delays on every color I wanted led to me check for other sources. Seems this complaint is common. Guess what? I saved $11/spool and got every color I wanted 2 days later.
Thank you Amazon Prime and the power of internet forums! There are lots of providers of PLA but people have a lot of trouble sorting them. From varying thickness of the strand's diameter to differing melting points of the plastic there is a lot to look out for. I found the SainSmart stuff to work very reliably.
After you order the plastic you will need to print a new spool holder. This pattern worked fine for me (I did rotate the model on the build plate, so it didn't build straight up!) Also, I read around on the internet and then experimented with extruder temperatures. The Replicator 2's default setting of 230F is too hot for the SainSmart, I find 215F works much, much better in my home.
I've tried Black, Red, Blue, Pink and Silver/Grey. So long as your build plate is level and the extruder is clear SainSmart works great!

Call it retro. Call it a throwback. Even call it kitsch. But the 80s are still a singular time in pop culture history. From Ghostbusters and Back to the Future to your neighborhood arcade and the Atari 2600, artifacts of that seminal decade still resonate, evoking audible excitement and sighs of pleasant yesteryear remembrance. But […]
