What causes the print heat to 'catch' on the part?

What would cause this effect, and how can it be avoided? This is a PLA print, and it should look like this. I tried 215 and 225°C and both had the same effect. An earlier similar print at 220°C was not as bad but it still had some catching- it…

Slicing software and Sidewall

I am new to FDM RP. I've done a lot of work on ZCorp and Connex. The question is can vectors curve drive an extrusion nozzle? Within a 3D volume I can generate curves that I want the print nozzle to follow. Is this possible or has it been done?…

Poor first layer bonding and bridging issues with Prima PETG

I have a roll of Prima PETG, I like the strength but I am having a few issues - the outside perimeter of the first layer often breaks away as a loose string (so it's not bonding with the second layer or perimeter next to it), small areas tend to go…

Makerbot Replicator 2 restarts after preheating the hbp

I've recently upgraded my Replicator 2 with a heatbed and the more powerful power brick (9.2A). The problem I'm having right now is that the Replicator restarts right after the preheat of the bedplate finishes. It does not matter which temperature I…

Applying Kapton Tape To Bed Plate

There must be a trick to doing a good job of applying Kapton tape on a printer bed plate… We built a Bukobot and even with a great deal of care ended up with bubbles under the tape and occasional overlaps. I'd appreciate any pointers.

Should I use different nozzles for different materials?

I know I should use different nozzles for filaments that use vastly different temperatures but what about filament types that use similar temperatures? For example, PLA and PLA composites like ColorFabb Woodfill filament. Should I use a separate…

Typical plastic strength at 1500 RPM

I'm planning to print a certain sample holder which is going to be placed on a CD-Rom BLDC motor and spun at about 1000-1500 RPM. The holder would essentially be a 2-3 mm thick 100 mm square platform with 1-2 mm thick hooks rising up from outer…

How to create attachable/detachable printed parts

I am making a part that needs to come apart, so I don't want to use glue or similar adhesives. I saw an article about printing snap-fit pieces, but it seems like you would need a lot of expertise to make it work well. Does anybody know of an easy…

What parts are strictly necessary for a 3D printer?

I've built the mechanics of my 3D printer myself, because I need to print parts that are really huge, (and for budget reasons). So, I already have the 3D movement functionality. But what I need now, is the printing mechanism itself. I've been…

I have used cyanoacrylate glue aka superglue to bond PLA. I have created several electronics enclosures. (Definitely the most time-consuming part of the project.) Now my question is which debonder/solvent can I use to separate the pieces again…
