Re: Favorite Print Surface?

Stock glass plate with some aquanet hairspray with PLA. the most important factor for making sure something sticks is making sure the bed it level and the Z-height is correct. So maybe include some better instructions on those two things as well as calibrations. I have used Buildtak in the past with...

Re: How can I slow the Z movement before the purge?

It worked fine for the first 6 months or so and then that started happening. It doesn't do it everytime. Last time I lubricated the printer I used the grease included with the kit and I don't remember if I did the smooth rods but I do remember cleaning them with isopropyl alcohol. I have some tri-fl...

Re: How can I slow the X movement before the purge?

I am an idiot.... yes I meant Z! Thanks for the help guys, I will adjust it and let you know what happens!

Last time I lubricated it with the included grease is when it really started skipping. Should I use a lighter machine oil or something?

How can I slow the Z movement before the purge?

Hello all, I have an issue where sometimes the Z motor will skip when it tries to move the bed up really fast right before it purges the nozzle. How can I slow this movement down? I have been just sitting by my M2 before it starts a print and helping the bed up with my hand to prevent the motor from...

Re: what would be the best filament for this application?

I was curious about using a smaller nozzle, I also have my extrusion width set to .40 so maybe lowering it to .35 could help.... I have been wanting a smaller nozzle to try some higher resolution prints anyways. The price on the resin printer that I have been looking at dropped from $1480 to $850 so...

I know there are a lot of plastic ducted fans out there but I couldn't tell you the rpms or anything on them, I ...

I have been flying rc for 20 years and I love 3D printing so I couldn't turn down the chance! Basically will be printing an 18 bladed fan that has a 150 mm diameter that will be spin...

Re: Resin based 3D printer discussion

I have seen a lot of parts that are warped badly on the bottom. Let me know how your low shrink resin does. I e-mailed Formlabs to see if they offer any military discounts, they do not but I was offered a free cartridge of resin, so that was nice of them. I also e-mailed CTC to see how quickly they ...
