3D Printer yet?

68.61 mm? That's waaaaay off dude!

[Brumby]

I have to admit my first 3 seconds saw that number as well.....

2nd XYZ Cubey after relevel & dropping bed temp to 50°C. Some X-axis banding indicates I need to tighten up the belt on the printhead a bit. That recurring blem on the top surface as the printhead leaves the finished print is something I should be able to fix in Cura; it appears on 3DBenchy too. Honestly, quite decent prints as-is, tho. 

Time to move onto the SS Benchy.

Toot-Tooot!

               

Very pleased with Benchy too. A few slubs in the finish on the hull, a little stringing on the underside of the roof, some clumping at the top of the arches. I could spend days tweaking to get rid of these, but really the only bit that bothers me is how poorly the print on the stern resolved; that should be a little more pronounced, even given how shallow the depth is. The random slubs on the surface are likely due to settings affecting the layer starting points; I can probably tune that out in Cura but like everything, there are tradeoffs.

Generally, I make functional pieces rather than decorative... so even if I don't change a damned thing, still pleased.

Try this one mnementh.

Currently working on a temp tower to get bridging somewhat under control. Then a petsfang E3 V2 so I can get away from these screamin-mimi 30-40mm fans.  Then, once I have the wind blowing my way, I'll try some stringing towers to get extrusion/retraction dialed in.

Then, I had my eye on this:

So Dave was given a Resin Printer but wasn't sent any resin to use it with When pointed out he would be needing IPA for cleanup too 

[xrunner]

LOL.

That is a truly wicked test print mnementh!  I can't imagine how you get those 90 degree overhangs to work (apparently without printing support).  I have found it easier to design those overhangs out of prints than to make them work.

[xrunner]

Here's what came off my printer. I did re-size the object because I didn't want to wait 14 hours for a 0.1mm resolution print. It's sized down 50%, so the small print is not clear, but the rest looks pretty good.

[mnementh]

@xrunner: I'll be tickled purple with pink polka-dots if I get similar results.

LOL! I haven't DONE the print yet... I wanted to try and get my cooling fans situated and the Petsfang printed/installed first. That is a computer render from the page on Thingiverse: https://www.thingiverse.com/thing:2656594

Actually this is the one I thought was crazy hard.  Sorry about the confusion.  The overhang test one seems doable.

Looks like there are some improvements to be had. What printer is that?

[xrunner]

What printer is that?

It was a basic Ender 3 Pro, but now it's hardly the same thing now. It has X,Y, and Z linear rails, a 32 bit SKR mini main board with TMC2209 silent stepper drivers, Marlin 2.0.5.2 firmware with manual mesh bed leveling and linear advance nozzle pressure compensation enabled (I compile the firmware myself), and a glass bed with a surface that is amazing in it's ability to stick the prints down.

It works extremely well and I am very pleased with it's accuracy and performance.

Some good ideas in this one from Angus for those still learning there way around Fusion 360 and 3D printed limits

Funny you should post that video, I just ran across it yesterday but haven't watched it yet. I've been using Tinkercad for my own designs and it's pretty powerful in it's own way, but I know I need to use Fusion eventually.

I've been stuck at a low level in Fusion 360 for a while, because I had a hard time understanding the "philosophy" of the way it all works, and the overwhelming number of selections presented to you on-screen. But I finally decided to keep watching the tutorials and I think I'm getting over the hump. For me, this person paved the way yesterday and I understand it a whole lot better because of his examples -



I'll design a trivial part in Fusion 360 and post it for your entertainment later.

I made this plate today. It isn't for anything specific but just for play. I might be "getting" it, at least for simple things.

  stick at it.

Rather than use the Hole function I find generally drawing the circles on a sketch easier. In the case of your design you could also then use the Circular pattern feature so draw one then add the three others with it. In your initial sketch this same method can also be used to copy one of the square arms into the four of them too. So your initial sketch would be one circle and three lines for one arm patterned into four then add the centre square.

Doing this there is no need to make the hole later as you never actually extrude it when doing the extrudes for the body.

Thanks. There are so many ways to do things in that program. I think that's what the intimidating thing was. I kinda basically froze after starting because I didn't understand the steps and there were so many menu choices. For whatever reason, the one video series I found yesterday seemed to get me over the hump.

Right now I don't see why I couldn't make anything I've already made in Tinkercad in Fusion 360. Yay.

Am I the only one who prefers to do parts and mechanisms in OpenSCAD?

[mnementh]

Yes. On the entire planet.

Bought a prusa 3 for my younger son that is at college, 3rd yr of mech eng. He is using it for fun, but also to make models/jigs etc for the suspension of their formula sae vehicle. This is done with solidworks.

I can send him solidworks files and he can then slice them etc and print them for me. When he visits (about 90 miles away) he brings the printed models to me.

I wanted an inline switch for powerpole cables. I use powerpole in my 4wd and various things plug in. Many have their own switch, but the pump I use to transfer water from tanks/wells to the bladder in my 4wd doesn't. So, designed up a small box that takes a powerpole pair at each end and runs the +12 through the inline switch. The switch is lit when 'on', so easy to tell what is going on.

Here's a render of the design. Has the slots to key with the powerpoles and also the hole for the roll pin to lock each end in place. Turned out quite functional.

Three good Fusion Channels well worth a watch. Brad and Lars do work for the Evil Empire of Autodesk but their channels are independent and just great resources. Kevin of Product Design Online is a fairly new one but lots of 3D printing based tutorials as well.

https://www.youtube.com/user/TheKHaug Really good Basics videos with some 3D printing

https://www.youtube.com/channel/UCo29kn3d9ziFUZGZ50VKvWA not a lot of recent content but his 'Absolute Beginners series' was excellent for me initially.
