Vulcan Grey Posted October 31, 2013 Report Share Posted October 31, 2013 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? Quote Travis Vulcan Grey 89SE Link to comment Share on other sites More sharing options...

Vulcan Grey Posted November 1, 2013 Author Report Share Posted November 1, 2013 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.

Vulcan Grey Posted November 6, 2013 Author Report Share Posted November 6, 2013 My son's friend has built this one. It works!http://www.k8200.eu/locale/ 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 http://www.3ders.org/pricecompare/3dprinters/ The one that I am looking at making is about $500, and has maybe more upgrade ability... http://www.youtube.com/watch?v=z99Vtyr5rg4 http://www.youtube.com/watch?v=od5GqSPq0cQ Quote Travis Vulcan Grey 89SE Link to comment Share on other sites More sharing options...

Vulcan Grey Posted November 25, 2013 Author Report Share Posted November 25, 2013 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. Quote Travis Vulcan Grey 89SE Link to comment Share on other sites More sharing options...

Vulcan Grey Posted November 26, 2013 Author Report Share Posted November 26, 2013 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!

bosbon_be Posted November 26, 2013 Report Share Posted November 26, 2013 At my work we are testing with Carbon fiber reinforced plastics. Just keep your printer and hardware as clean as possible because the Carbon dust is verry conductive and will destroy your electronics.

slewthy Posted December 18, 2013 Report Share Posted December 18, 2013 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. Quote "Intellectuals solve problems; geniuses prevent them."

Vulcan Grey Posted December 18, 2013 Author Report Share Posted December 18, 2013 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 http://www.engineering.com/3DPrinting/3DPrintingArticles/ArticleID/6801/GEs-Announces-3D-Printing-Design-Quest-Winners.aspx http://www.engineering.com/3DPrinting/3DPrintingArticles/ArticleID/6824/Miniature-DMLS-Prints-Tiny-Metal-Parts.aspx Here's one that you can build yourself... http://www.engineering.com/3DPrinting/3DPrintingArticles/ArticleID/6755/Low-Cost-Open-Source-Metal-3D-Printer.aspx not as good as the professional ones though...

slewthy Posted December 18, 2013 Report Share Posted December 18, 2013 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? Quote "Intellectuals solve problems; geniuses prevent them."

Vulcan Grey Posted December 18, 2013 Author Report Share Posted December 18, 2013 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.. Quote Travis Vulcan Grey 89SE Link to comment Share on other sites More sharing options...
slewthy Posted December 18, 2013 Report Share Posted December 18, 2013 Yes please! I'm sure I'm not the only one with this issue. Mine is currently badly and visibly glued with araldite epoxy.

Vulcan Grey Posted December 18, 2013 Author Report Share Posted December 18, 2013 Is yours the older style or the later ~89 style? http://www.lotustalk.com/forums/f164/wiper-arm-catching-itself-1984-a-134681/ 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 Posted December 18, 2013 Report Share Posted December 18, 2013 Mine is most like the bottom image- it clicks over the ball mounted on the bottom of the screen.

Vulcan Grey Posted December 21, 2013 Author Report Share Posted December 21, 2013 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 https://drive.google.com/file/d/0B2nifoCpaFSfNThzakFtNjZnNFE/edit?usp=sharing https://drive.google.com/file/d/0B2nifoCpaFSfS1dIRWNzaXp4Z0k/edit?usp=sharing Quote Travis Vulcan Grey 89SE Link to comment Share on other sites More sharing options...
slewthy Posted December 30, 2013 Report Share Posted December 30, 2013 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. Simon Quote "Intellectuals solve problems; geniuses prevent them."
