Like for the 300, 400, 500 series? I do ave a set sitting around that i could model up and try. Interesting thought...

Yes those very ones, Toro quit making them...

I'm trying to think of other common parts I could model up and print as the old plastic starts to fail on these great machines

If you are interested in making and selling the handles you just made, put me down for a pair of them...very nice job..:)

I'd love to see one of those printers in action in real time

So how difficult is it to work one of those 3D printers?

Its not that exciting. Its really rather slow. That said next time I'm printing a set of these I'll take some video and post it up

I can make a few sets if people are interested

In theory its really simple. However, there is sort of a black magic to them to get a really great print. Different materials have different properties, even different colors of the same material can print drastically different. Knowing what is/isnt good for printing is also key as well as how to orientate and tweak the settings to get he best results for any given part takes a lot of practice and experience. There are at least 5-10 settings that I tweak for each print to get the best results.

 

The other thing that is a huge disconnect is that unless you have the skills to model and design something in 3D cad, all you can really print is trinkets and random "junk" that you find online. I honestly think that's the biggest reason they aren't a household item yet. You essentially need that middle step between "I have an idea" and "I have a physical part in my hands" which is the ability to use a cad program.

 

Then finally there are certain atributes about 3d printing that just isn't great. They are really only "strong" in 2 of the 3 axis'. When it a print fails its usually due to layer separation. Once again, you can avoid some of this with experience and designing a part that is specific to 3D printing that you may not design that way it it were injection molded. 

 

So is it difficult? Yes and No :)

Well I thought I knew where my set was, I'll have to keep digging for them. I did find a set for the black hoods. I would think those are also no longer available?

Interesting... I have a 3D printer in my classroom that is nearly the side of a refrigerator, I cannot believe I have never thought of printing out the plastic bits before!  What kind of model and support material do you use?  Does your printer heat up on the inside or just the nozzles?

Quite aware he has them, but when I have the tools and the means I'll try it myself! Also, I'm assuming Glen just makes molds of existing parts. I wanted to add the lock nut to mine so it will never work itself loose from vibration. Thus I had to redesign and print it.

This part was printed in PLA as its nice for quick prints. I'll likely print another in ABS when I get the chance. No support material. I always try and design my prints to have no supports. This is primarily due to the fact that its a single extruder machine which means any support material is the same as the regular print material which makes supports more difficult to remove. Also, no supports mean less print time!

 

Printer has a heated bed. It is enclosed but I haven't added an ambient heater yet. I plan to do that soon as that will greatly help with warping caused by uneven cooling of the parts.

I'm a mechanical designer/engineer also, and we use NX for our 3D modeling.  We also have a 3D printer in my building, and we use it some to make development type parts.  In another building within our company, we have 3D printer that makes metal parts.  A good 3D cad program are pretty expensive, so that's big obstacle for those seeking to do 3D printing.

Justin, great job on that knob, I often wondered if I broke it. Thumbs up.........

I have a Dimension 1200es.  This is the first time I have ever had a 3D printer in a classroom.  It has a pretty slick set up; model material and support material heads that are headed, plus an environment heater so the whole unit gets hot.  Print time is a bit slower for larger parts and they usually have to take an acid bath to remove the support material, but I'm certainly not complaining one bit!

Impressive machine! My personal printer has about the same build volume but is definitely not a professional model. I actually got it from a local model shop that I do a lot of work through for my job. It was broke so I got it cheap. I redesigned the whole XY gantry and built a custom hot end for it. The one I showed in the photo up top is the one on my desk at work. 

 

I did manage to find my headlight inserts for my 300 series tractor. It might take me a while to model up as its actually a rather complicated geometry. Will post up something once I get to it. May also look over the other parts of the tractors and see if there is anything else I can print that isn't currently made by a vendor or available through toro.
