3D Printing Group

Hey all,

Here are some D&D miniatures I just printed on a Stratasys F370. Below the image are the print details.

Details:

Light Grey ASA

GSR Support

Slice Hight - 0.0050 in

Optimized Tray Arrangement (GrabCAD Print)

Wow, that makes me wish we had 3d printers back in my D&D days!

Here's my latest, the first two are an adapter for fan trays to be tested on a flow chamber and in a sound lab. It holds the trays in their proper position and connects to a calibrated inlet plenum (to replicate the pressure drop through the system it cools) and multiple discharge plenums representing different field configurations. There's a small flow chamber in the background.

Natural color Duraform PA material

Here's it's twin being fitted with 8020 legs and the calibrated inlet box (it's upside down in the pic):

Here's a couple pcb and blower assembly holders that align the pcb with pogo pins used for programming and other electrical work on the boards under development.

SLA process

Accura 60 material

My favorite thing about 3d printing is the ability to create geometry that would be difficult (extremely expensive) or impossible to pull off any other way, and I leverage this attribute highly when designing early proof-of-concept stuff, fixturing, and the like.

Nice work guys.

I'll have to find some prints that I can actually photo. Most of the stuff I work on is regulated under the U.S. department of commerce. Not nearly as much 'fun' as Gabe's miniatures.

However, I can safely say.... this one (was actually an assembly at one time) holds a part at an angle for x-ray inspection. This is built from Accura Bluestone (composite). Not too fantastical, but functional and eventually retired thanks to the new machine with nutating head. No love lost there.

I usually incorporate nut bosses for fasteners.

I had to print litlle gears for a friend of mine. His old radio used 31mm gears, and they cracked over the years. The "crazy" part, is that the original gears are quite flexible, so I had to mimic that hence the weird design !

Printed on a Ultimaker 2+ in Nylon, 0.25mm Nozzle, 0.06 mm layer thickness.

Gabe, those look great for an FDM process.

I think the new lab where I am working just so happens to have the F370 printer. I'll have to double check tomorrow.

A few questions:

1. Where did you get the files? Are those from Miguel Zavala on Shapeways? Or another source?
2. Any finishing or post processing done? I've only seen one piece off of the printer thus far, but it had some heavy stair-stepping from the layer thickness.
3. Do you have a closeup photo of one of the models to better see the surface finish?

Thanks.

Adam

Hey Adam,

1. Yes I got them from Miguel. His models are awesome and have been super fun for our adventure so far.
2. No finishing. I used soluble support, so the only post processing was putting those models in the baths.
3. I used a Stratasys F370 and .005in slice height. See below a super zoomed in look at the shark man. (end of his spear is broken a little.

Best,

Abe

not a specifically great quality (because of extreme warping) or complexity in the part, but pretty cool that I got to make a giant part that fills most of my printing volume (Ø200mm H230mm) in only 8h (I have a 1 room appartment, so I can't really print during the night)

the part is mean't to contain 20cm long dupont wires in male/male male/female and female/female flavor

and the printer is a 3KU K3000 (400€ kit 2 years ago, I was looking for a rigid printer and this one is fully made of metal + quick because of the 1 room thing, so I was looking into delta printers)

1 Liter Can

That's really cool. How much support was needed inside the can? Also have you done any post processing to make it water tight?

No support needed inside can. Direct finished part.

Fresh off our Stratasys J750. Looks pretty real, right?

We made frame structure for our Land,Air and Water drone

Above picture is the cad design we made.

Here is the printed and half assembled drone

I don't have a photo of the printed part, but I made this hook to hold my headphones on the side of my desk:

Grabcad model

Headphone Hanging Hook

There is no shortage of headphone hanging options, this is my solution. This is sized for AKG K240 Studio Monitors, but other headphones should fit as well. The model was designed with 3D printing in mind, and was created on a Stratasys F270. I think it would also be an excellent model for castin...

Black material was loaded in the machine, but some primer and paint will make it red if I really needed it to be.

Awesome print! Used my MK3 Prusa. Very nice gift for children or loved ones. Give it a try guys.

Just printed these cool coasters on our Stratasys J750. I changed the colors from the original file by selecting the faces in SOLIDWORKS and changing the color of every face on the part.

@singlefonts those look awesome! What are you using to print those on?

Wow cool! So all in all how long did it take print time and post print time to get those awesome finished rings?

Primary mirror cell and cover (400mm dia)

These are all part of my 14 inch Dobsonian astronomic telescope that was designed in Solidworks.

They were delivered within a week, after ordering.

@alex.y-1 how did you add the inserts?

What do you exactly mean with inserts?

Sorry, maybe the wrong term. The metal parts that you have added to the assembly. Did you build with the tolerances in place for those inserts?
