I'm a Shark!

[Andrew]

The rudder is giving me fits! As noted above, I printed it as per the stl file. I broke off the little tab, twice. So I tried printing it laying on the leading edge, thinking that would give me more strength on that little pin.

The part completely delaminated, just above the brim. Each layer just broke apart. Then my printer stopped extruding all together! Yeah, that 230c on the hot end with 50% fan was not going to work.

I took the hot end apart, cleared the jams, and reset everything and tried a different approach. I dropped the temp to 205c and increased the fan to 100%.

Two hours later, and darn that looks good. Until I tried removing the supports.

My latest gnome-print failed as well. The legs separated just below the body. My prints are just coming apart at the seams. *sigh* It's a learning process, I know. The Shark is an advanced print, I know. My current gnome print isn't really even printable. I know.

I'll figure it out. Learning process. Advanced procedures. Trial and error. Live and learn. In the Army we'd say "Suck it up and move on!" We'd call it "good training."

Those phrases are as frustrating now, as they were way back when. I'll get it figured out, but darn if it isn't frustrating!

You need to find the sweet spot for your PLA temperature, with my white PLA it's about 195° if printing fast and I may lower a bit if printing at a slower speed. I've been printing like mad the last couple of days, changing settings here and there, what's good for one shape can be bad for another, then you can't remember the exact same settings for the other part that was working well.
I was printing a fuselage over night while I was sleeping, woke up about 3am to switch it off because I could hear it had finished, but no, about 90% of the way printing it decided to make a bird's nest instead 😁

Edit typo: 195°

I printed mine with no supports at all and it worked well. Where you were having all the stringing a few days ago I would pull your nozzle fan off and remove it from the holder. on the ender 3 and 5 there is such a small gap between the center of the fan and the metal housing it traps hairs and spins them into a ball and slows the fan down. you can't really tell just by spinning the fan but when you remove it then you see it.

Well with these thin walls that is where the hi temp comes in of 230 for good adhesion and if anything no fan at all. Printing thin the fan will cool the filament before it has actaully adhered to the layer underneath.

You could try increasing your flow % and or even layer height but stick with the higher temp.

So sorry, I haven't slept much the last few days. I ment to say , 195°

I print mostly in the 210 to 220 range but there are some colors that print horrible in the higher temps .

230 seems extremely high for PLA. That said, every printer/filament/color/part combination has it's optimal temp for printing. For PLA on single/thin wall prints, I run the first layer at 215, and the remaining at 205. That gives good bed adhesion, and then not too melty for the remaining layers when stringing can be an issue. Hotter usually leads to more stringing. Small layers that print too quick may sag/blob if there is too much heat. More layer cooling on PLA may be necessary on overhanging parts and parts with short layer time.

Just my quick $.02 from printing the 3DlabPrint easymax001 and Eclipson Model-V planes, and several other single-wall projects.

Cheers!

peg and hinge. I just spent all last week making a Herome duel fan mount. never thought of turning it off. for the heck of it ill try my next print with no fan and compare the 2

 

[buzzbomb]

Well, it took a couple more tries, but I got it!



210 degrees C and 50% fan seems to be the ticket. I printed it in the original orientation with no supports. On to the next bit!

in spite of everything, I managed to get it glued together. I found that if you lay a bead of super glue down then sprinkle baking soda on it, it makes it kick instantly and leaves a raised line that you can sand down and blend in. Also works well for filling gaps.

Looks good, I might have to try the baking soda trick. I usually just wipe the seam quickly and the give it a shot of kicker.

does anyone happen to have a curaprifile for the gills? I have tried like 6 times but can't seem to get even close to a decent print. This is what im getting.

 

[sundown57]

no gills but all wired up and ready to maiden. I have to admit the landing gear is very cool. Spring-loaded on all 3 wheel and steerable front wheel.

I think I've got it.

Don't move the model. Just print it as it imports into Cura. Don't forget the hairspray!
Here's the profile:

The have to be standing up.

My daughter texted me yesterday, said she was at Walmart and wanted to know if I needed anything while she was there, I said, Yes, Aquanet hair spray and white nail polish, she said, OK does dad need anything? hahha

@buzzbomb curaprofile worked great. got those printed and got the spinner printed. now just have to maiden it.

 

[buzzbomb]

We continue! Believe it or not, I'm almost done with the gnomes. Overnight, I printed this:



It actually took a couple nights of tweaking the profile to get it right. I'm happy with it, now. That's fuselage part #3. That makes my fuselage complete! I guess it's on to the wings!
