Tooling "Wish List"  

RE: Tooling "Wish List"

In the Prusa Live #35, the tooling was mentioned and it will be printing only for initial release. That didn't rule out more tools to be added later...

RE: Tooling "Wish List"

Some sort of automated print removal tool would be nice. I can only think of way too expensive solutions with robot arms or extendible metal rods on a 360 degree hinge though.

As a thought experiment imagine automated benchy printing in 2 corners of the XL. Once a benchy is finished, the printer immediately starts printing the next one, while the print bed under the finished benchy cools down. At a certain temperature threshold the print removal tool carefully pushes/grabs the benchy off the build plate and then continues to print.

I think the move to print in another location for the next print is doable and more likely than the robotic arm or conveyor belt.

RE: Tooling "Wish List"

Probably it is possible to be added something like that, but it generates a huge amount of dust. I have a small CNC router and even with proper dust collection it is extremely dusty. This is not something that i want in my 3D printer.

RE: Tooling "Wish List"

My large CNC is basically dustless.  I guess you do not have a proper dust collection system.  I have a system I can wheel from my CNC to my Lathe to my saws.  It really produces a lot of suction.  You have to pay for a good dust collection system.

RE: Tooling "Wish List"

For a CNC you need something larger than the XL.  I found AVID CNC to be a nice choice to follow on from 3D printing.  Build your own and expand....

RE: Tooling "Wish List"

Not necessarily.  My cartwright is very handy and smaller than the XL.

I think everyone is going straight to the thought of cnc as a way to cut a raw square block of plastic into a part. This machine will definitely not be heavy duty enough for that. Rather the "cnc" head would be just to slowly trim very thin amounts of plastic between layer extrusions or every 4 layer extrisions maybe? Cirtanly this would not be of any value compared to the cost for even an average $4000 printer buyer but having the capability to produce dead on to +/- 0.01" dimentional accuracy right off the printer would be pretty amazing for engineers and more advanced users. If chip extraction is an issue a shop vac on a relay that turns on when the spindle is on would take care of most plastic chips. 

RE: Tooling "Wish List"

I am talking wood or soft metals and it is more about engraving than cutting.  I have no need to trim plastic.  Far cheaper machines have done it.  I am not buying that it is not heavy-duty enough.  It may not happen from Prusa but someone will do it.

RE: Tooling "Wish List"

OK, I will do so

RE:

It would, but I imagine the wood shavings would not mix well with lubrication and axis movement…

RE: Tooling "Wish List"

Haven't visited this thread in awhile, but had a couple of other thoughts. As regards a possible laser cutter head, how much power would be needed to be able to cut heavy card stock or "poster board" weight material", 500mW? 1000mW? Another good, easy to implement (IMO) would be a "drag knife" cutter, essentially turning it into a Cricut machine. Would require a renewable "spoil board" (cutting surface) with a +Z offset, but I don't see that as particularly challenging.

Has anybody seen anything that looks remotely like a proposed tool library, either from J.P. or anybody else? And when is my 1st day pre-order going to ship?? My footprint real estate is almost ready!

RE: Tooling "Wish List"

Now tell me, to cutting acryllic through lets say 4-5mm , how powerfull laser you would require. I believe it has to be watercooler CO2 laser which is no chance to mount in in prusa. The blue laser engravers are just toys.

I was able to cut red translucent acrylic with a blue 10W diode laser. It was not fast and the edges were showing some slight deformation from longer heating, but it can be done. White or blue acrylic OTOH probably reflects too much of the blue light and I was only able to crudely engrave it, not cut. 

About the cardstock - I am sure it depends on the color 🙂 180g white paper needed significantly more power than a brown corrugated cardboard from a cardboard box but both were possible with the 10W and quite fast speeds, and I believe 1W or 2W diode could do it.

A drag knife needs some pressure from the top, preferably quite controlled from what I see with my cutter. Should not be a problem for vinyl or paper with a sharp enough knife, but I would not want to use it for mylar stencils 🙂

RE: Tooling "Wish List"

What I'm hoping to see:

- Seamless integration with different nozzle sizes. My Mk3s+ basically lives semi-permanently with a 0.25 nozzle for maximum detail with text/sculptural detail. That tends to hurt print times though.

• Outer 2-3 shell walls with 0.25nozzle
• Inner walls and infill using 0.4/0.6 nozzle
• Supports with 0.4/0.6 soluble filament

 - Slicer smart enough to see that a layer doesn't have sharp 'edges' and can switch to the larger nozzle for those layers. Larger layer heights if appropriate too wouldn't be terrible. 

RE: Tooling "Wish List"

talking about dust management system, I found something very useful, sharing link:

RE: Tooling "Wish List"

To my mind, adding a laser, scanning, or milling head would be a mistake.  Combo machines have the reputation of doing (at best) one thing well.

RE: Tooling "Wish List"

No CNC on a 3d printer. You would be hating life trying to clean everything up. I have a CNC and hardly ever use it anymore. With 3d printing you shouldn't need the CNC. If you need a CNC buy a dedicated CNC machine. They are two different animals. The XL platform couldn't handle the CNC option.

RE: Tooling "Wish List"

Now that we've seen the speed and reliability of the tool changer, I'd say a CMYK inkjet print head.  There are several implementations (Da-Vinci, Stratasys, etc..).  Basically it prints in a ink absorbing filament, then paints the layer with the CMYK head. 

RE:

That would be interesting, I recall a print test where someone painted white filament with sharpies. The results weren't half bad. Found it: https://www.youtube .com/watch?v= UnWxbU7Hfro  Fix the link.. it was failing to show otherwise.

However, without a proper hood system I'd really recommend not doing this. At a minimum you'd have to find non-toxic cmyk inks that can handle high heat.  Back in my college days I added india ink to a bunch of melted glue sticks.. that.. was a mistake. The fumes were horrid.
