3D Printing Journal Continued

I have started printing again after I got back from vacation. A lot of warping on a modest sized print in ABS plastic. It may be my imagination, but Makerbot’s Brown ABS filament seems to shrink and warp more than a color say like Red.

Oh, and I started getting temperature errors again 🙁 . I have not investigated this yet. It is just too depressing to look at right now.

PLA is still a non-starter on my Makerbot Replicator 2X printer.

There is a gift I want to  give to some of my relatives this Christmas. I am designing it and I want to print copies out and give as gifts. At the rate I am going, I am spending more time fixing the printer, having failed prints, etc. than I am designing this gift and printing its parts.

I decided rather impulsively to go to the nearby Microsoft Store and buy a Makerbot Replicator 2 printer (not 2x). It prints only in PLA. So far, I have found it to be much more reliable than the 2X. If I level the build plate properly it has a very high rate of successful prints. I am getting back to designing this gift in Sketchup again. Yay!

Note: The Makerbot Replicator 2 looks a lot like the 2X but… it cost less, does not print in ABS, has only one extruder not two, does not have an aluminum build plate, its build plate does not heat up (no need to for PLA), the extruder itself is different, there is no plexiglass on the sides and front, there is no plastic lid. So far… so good.

They have a demo printer at the Microsoft Store, it seems to be printing merrily away without filament cruft laying about. They sell a handful of PLA filament colors too. I will need to order some other colors from Makerbot that I need to print my gift out properly.

Getting the PLA prints to get unstuck from the build platform of my new 3D printer is harder than for ABS prints on my 2X. But I will trade successful prints for this problem any day!

I have notice that PLA can shrink… but a whole LOT less than ABS. I have a hunch that the really neat photos of say the green tractor on Makerbot’s site where printed on the Replicator 2 in PLA. I don’t know for sure, but I think I am right. I printed some tractor parts in ABS on my 2X (http://www.thingiverse.com/thing:31702)… there was a lot of warping. I printed the body of a UPS Truck in Brown ABS, there was a lot of warping and splitting (http://www.thingiverse.com/thing:31686).

Other Stuff
I got a new desk for my workshop at Office Depot to put my MacBook Pro on and hopefully it will be a future soldering station as well. My workshop is looking more and more “workshoppy” all the time! 🙂

Do I have too many proverbial balls in the air at one time? Probably!
