3D Printing


20mm Deadmans Corner building (3d print)

This is one of my latest prints,  I used Prusa 3d splicer program.   Not as my headaches  was with cura 4.2,   Still I need to fine tune the print.   I have the right to sale this and more of this series.  My next print will be still in 15mm scale.    Hope you like the print.Deadmans CornerDeadman's corner mapM5 that was knocked by Pak 40.  The commander was burned alive getting out of the turret.

The Prusa 3D Printer is Fixed and Working!

The replacement Thermistor arrived on Wed and I actually managed to get it installed correctly on Thursday.  My Prusa is back up and working.  I must say I'm really impressed with the quality of Prusa's customer service - the part was dispatched from the Czech Republic on Friday and received in Maryland by Wed.  There's also a superb set of instructions online of how to replace a thermistor which made Thursday's "operation" rather easy.The first print from my newly "thermistorized"* print head is a warehouse roof.  Perhaps not the most exciting of subjects but I've made a commitment to the club to print off a warehouse and paint it up.How big is this warehouse?  I'm 25% done with the two sections pictured.  There are three more building/roof sections to print out!You may see this warehouse in an upcoming LWTV video....Anyway, I'm really happy with the Prusa printer and the level of customer service.  There are less expensive printers out there but I think the combination of

Prusa I3 Mk3S - Thermistor Woes and Superb Customer Service

Last night I kicked off a 15 hour print for a "secret LWTV" project.  Ok it may not really be all that secret - I was just trying to sound cool.  Anyway, the print seems to have stopped at the 94% completion point and I was seeing a mintemp error on the printer's control panel.After inspecting the printer it looks like one of the wires to the Thermistor has broken from wear and tear.  I'm 99% sure this is from use error as I've been struggling a bit with the filament jamming and have taken the print head apart at least 5 times so may have not made sure the wire was clear the last time I reassembled the printer.I went online to the Prusa support site and was able to quickly diagnose the issue via their superb documentation.   I took the picture you see above and then opened a chat box with Prusa support.  Horsa jumped on the chat with me and quickly confirmed my diagnosis and just sent me a new Thermistor for free.  Thermistors are cheap but this unit is coming from the Czech Repu

Samurai farm houses update

Been on vacation for a week.  Last night I got back to printing on my ender 3.  Today I firing up the CR-10 to print my Samurai farm houses.  Got a good start on this set. After taking inventory on the parts I printed. Need to print more of the middle sections.  Than back to making roof section.  The prints are excellent.  I had a few problems with the starting end curling. But that was me not making sure I had good adhesion on the printing surface.  With the parts you can making many different houses for a game or D&D.  Below are examples of what you can build.   Currently I'm kicking around the idea of getting license to print there building.  That is if I get enough interest.

Prusa Progress: Done!

 Whew - the printer is now fully assembled.  Despite an insufficient supply of gummy bears, this was a really fun little project.  I made a few mistakes and had to backtrack a bit but I enjoyed building this sucker.Now it's time for my first test print: Well, that didn't seem to go all that well.  I'm pretty sure the Prusa logo isn't an abstract piece of art.  The troubleshooting guide on the Prusa website is very well done and I quickly diagnosed there were two problems - one of the drive belts (the one that moves the platform) was too loose and the print head was too close to the base.A little repair work and let try again.The printer does comes with a first layer calibration routine which I ran about 20 times tweaking the settings.  It prints a single line in a zig zag pattern and a small flat piece.  Useful for diagnosing, boring to blog about.  SO you only get to see the test results of full items.Boom printing like a champ. If you are considering getting into

Prusa Progress: Extruder Complete and LED attached

The extruder/print head is finally done.  The instructions indicated this was the most complicate step and I can attest to the veracity of that statement.  Each individual step made sense but there were a lot of them!  I will say the instruction manual is superb.  I also recommend using the online version which has a few more pictures and toy can zoom in on them.Next step is the assembling the heated bed and then hooking up the power unit with the electronics. There is one GREAT LIE with Prusa 3D printer assembly.  The company includes a nice package of gummy bears that you are supposed to eat as rewards for completing certain steps.  There just aren't enough gummy bears relative to the work.  Somehow my gummy bear stash has been depleted before the uni is done.  Perhaps I should substitute beer for the remaining steps. What could go wrong?
