New Shapeways material

[Lemosteam]

Here are the various glues I have and tested.  They are aligned in the same order as the styrene sticks  All are able to lift the roof as shown.

However after removal testing
1: the styrene glues did not adhere to the material and pulled off quite easily.
2: the poly glue stuck to the material, but not the styrene.
3: the CA glues worked well, the blue cap pulled a hole through the material, the Green cap i was more careful with and was able to break the glue, with some remaining on both parts.

... Printing method and the orientation that I think they printed it in.  This printing method uses a table that is pulled up out of the fluid and the printing occurs at the bottom or near the bottom of the vat (like a Form 1 video).  @bbussey , it is unfortunate they chose the side of your truck as the support side- had they chosen the top or bottom of the trucks, the sideframes would have been perfect.  The process basically starts as the initial smooth surface, like a pool, and that is what is at end of my roof and the sideframe on Bryan's truck...

@Lemosteam — John, that still doesn't explain the smooth surfaces on the inside face of the truck frames, unless every face of the model that faces the build plane ends up with a smooth face.  I may ask for clarification on how my parts were built, since as you pointed out it would have been better if they were built with the truck base facing the build plane.  The driver centers were built standing on the long edge and there are no shiny smooth surfaces, but there is evidence that the entire edge had build supports.  There's not enough relief on the inner lip of the rims to determine if they are overly smooth and shiny.  Also, I still have to test the functionality of all my parts.

Okay, I just tried my components and discovered two things. First, the material chips easily even though it had some flex to it, so it's not similar to delrin. More like an acrylic with a little give. So small thin parts are not practical to be rendered in this material. Second, the FXD is more precise. The FXD driver centers fit perfectly in the Kato GS4 wheels, while the new material, not so much.  Also, on the EP3 truck frame, the gears were binding. Once I reinstalled the FXD truck frame, the unit again ran smoothly. So, I'll be sticking with FXD (or polyurethane castings of FXD masters) for now.

Thanks for the review guys! I was a bit hesitant with this material, for now I'll stick with older materials.

Its been mentioned that an item being printed came out of a pool of material... maybe folks ought to check out this report from CBS News about new 3D printers...

LOL, all we've been getting is how much better and faster the technology is getting.  Meanwhile, nothing seems to be happening now.  Still waiting for the influx of all the SLA printers that were the talk of the industry 2-3 years ago that were going to change the industry and be affordable to the masses.  Also waiting on the huge HP campaign that was, again, going to change everything.

At this point I'll be lucky to 3D print my own casket (*****, I wonder if anyone else has though of that  ).

LOL... heck, I'll be fine with the bag and box my ashes will be delivered in since I expect mine to be dumped on a rail line near near me so there's no point in considering a fancy-smancy 3D printed urn...

Great idea but in my family there is barely one modeler and that is me... no one else to use me up...

This is HOn30 and was printed in this new material:

Yeah, but what does the other side look like?   

[Chris333]

He has a video of it on a spinning table, but it's on Facebook.

[Lemosteam]

Watched that video, nothing revealing.  I suspect it was printed from the bottom up.  There are no macro shots up close, but the one shot he has, no one seems to notice a ripple about 2/3 up the to the bottom sill of the Windows is an obvious shift printing to form a ridge all the way around the shell, similar to my roof.

[Chris333]

The floor, body, and roof are 3 separate pieces. Yeah I'd have to hold it in my hand to know for sure.

Got my 1/4 tank car sample and I like what I see.  Sorry about the pic, but I'm not going to try any harder being shiny black. 




They printed it on end which I knew I was leaving myself open for, but there's enough curvature on the ends and dome to see that it's much better than FXD in this instance.  My sample still had some warping even with thicker than minimum walls, but it's not bad.  Probably going to have to work with SW on how to print this since I think it's be best printed as one piece, but SW isn't going to want anything they can't get in and clean.

I think my 19,000 gallon tank car project can get moving again but will have to design it with both FXD for details and this new material for the tank which unfortunately will bring the cost up.  But by the time I'm done with this, RTR tank cars will probably be $60, so I'll call it a wash.
