3D Printer


Vulcan Grey

Recommended Posts

I'm planning on building a 3D printer kit very soon.  Just doing my research now.  No I'm not trying to print a gun.

 

Looking for a minimum of a dual extruder.

 

Been looking at the Rostock Mini, though not many dual extruders on those, due to need for less mass on the head end.

 

Also looking at Robo3D for my work.  Those are back ordered 8-12 weeks though.

 

 

Anybody have any experience?

Aren't Makerbot becoming the market leader in this tech?

The patents for fdm (fused deposition printing) expired in 2009, so the tech went open source. Many different printer designs are now out there to download and try for free... including the software and firmware.

Makerboot were open source, until they were bought by Stratasys and turned to the dark side of closed source.... Also, they charge $2500, I can build one for $500.

The open source community is moving more rapidly with innovations like multiple extruder and filament materials, along with software.

I'm looking at a Rostock design that can print much larger parts 8x8x16". But those rarely have dual extruders.

Also thinking of going with a Rumba circuit board rather than the usual Arduino Mega.

My son's friend has built this one. It works!

This doesn't look like a bad kit.  Their website says that they have a distributor near me (an electronic supply store that I often go to...)  But I can't find the price... other than on this site, which lists the price as $955

The one that I am looking at making is about $500, and has maybe more upgrade ability...

I finally received all of the parts to start assembling my printer!

 

I did already get the firmware flashed to the controller card, and checked operation with the LCD.  That worked fine.

 

Now I need to test the steppers, the heated nozzle, and heated bed, and begin assembling the hardware.

Does it print chocolate? :huh:

It could.  I would either have to find 1.75mm spools of chocolate filament.... or install a heated syringe on the extruder and keep the bowden tube warm...

 

Eventually I'm going to try it with 3 extruders, so I could do a hard plastic with rubber overmolded parts, or 3 colors of the same plastic, or 2 colors and support material for better overhangs...

 

I also want to try the new carbon fiber reinforced PLA plastic filament for printing, conductive ABS, and Delrin and Ultem!

Metal 3D printing may be some way off for home use but we are currently using this technology in hip replacement

This is '3D printed' titanium alloy bone replacement by electron beam melting. Same as the plastic but a bit hotter!

Has transformed our practice over the last 18 months or so.

yep, Since I work with hearing implants, I have looked into the 3D printing using the Selective Laser Sintering method, many times over the last 13 years.  The field is definitely improving!

 

Here's a few more

Here's one that you can build yourself...

not as good as the professional ones though...

Interesting!

 

Now, could a 3D printer create a replacement windscreen wiper arm ball joint end? Tough enough?

 

A friend of mine has one for his 'inventing' schemes - is it doable? How would I get a design to him?

you could.

 

I actually had to replace mine, first thing I ever fixed on the Esprit right after I bought it.

I made a small aluminum ball joint (shape of a baseball cap) with a captive clip under it to hold the ball.  Still works to this day.

I can't get to google drive at work, but I can send you my ball joint design later.

 

The original was ABS plastic, so you should be able to print an ABS part that should last a while...  They also have some newer plastic filaments for the 3D printers, like carbon fiber reinforced..

Is yours the older style or the later ~89 style?

My design is to replace the bottom plastic ball joint seen here, not the older style, which is the ring 2nd from the top.

Slewthy,

 

Here is the wiper fix. It has been in use for many years (~13).  Before I made this, my temporary fix let the wiper arm chip out some of the glass!

Here are the .STL files, which can be printed on a 3D printer

Travis,

Thanks so much for this. I will either pass this on for a machinist to make the ali version or my friend and his 3d skills.

 

Appreciate your effort.
