Which Printer?

Hi all, I have an Affinia/UP which I am very happy with. Been running for a year without any service. Question 1: Do I need to do ANY maintenance on this thing? It runs great, but I suspect I need to oil the transport mechanism some how. Any ideas? Question 2. I need a bigger printer volume for some...

Re: how do you water tight a sketch up model?

30 years? That would mean you were using CAD software in 1984? I'm curious what versions you may have been using? I believe AutoCad may have just came out around then. Soon thereafter there were a very small smattering of 3D programs. On the PC, the big one was Cubicomp-- and they had their own fram...

Re: What CAD/3D software do people use?

For 3D Printing, it's important to create 'watertight' models, and typically the software which does this best are the group know as 'solid modelers.' 3DMax, Alias, MODO, SketchUp, Softimage, Blender3D and others are "surface modelers' and they do not automatically create 'watertight' models. While ...

Re: how do you water tight a sketch up model?

I used to use SketchUp for all my 3D modeling, but after continual challenges trying to make a surface modeler (SU) create solid models (STL), I have since switched to Autodessys Bonsai3D (or FormZ the higher priced version) which behaves similar to SketchUp but creates solid models-- so no problems...

Re: Stratasys vs. Afinia patent issue

Interestingly, they did not sue 3DSystems who also "violates" some of those same patents. It's clear if they 'get away' with suing Afinia, they will sue every small defenseless startup because they know they can intimidate others out of business. Not unlike SCO tried to do years ago w/regard to UNIX...

Re: 3D printers Advisors

Oh, and P.S.: I happened to look at my Afinia User Manual today for the first time (I've had the printer for 8 months, lol) and there are a few paragraphs in it regarding warpage. They say that to minimize warpage you should do everything you can to make the entire printing process as fast as possi...

I was able to create a number of interesting products, including the creation of a saltwater aquarium media reactor, of which I actually marketed in some local forums and sold a few. As sales started ramping up, I decided to get another printer. Since you mention a production environment, I'll just...

Re: Attempt at non-biased in-depth review: Afinia vs Cube

I don't know what you mean by "putting a silicon pot stand on the build platform"? Can you explain a bit more? How does it help heat the platform quicker? I assume roller is talking about using a trivet, or an insulating hot pad, that you put on a table to keep a hot dish from ruining the finish on...

Re: Attempt at non-biased in-depth review: Afinia vs Cube

I have a $600 Win 7 machine hooked to my printers full-time so there's never a boot or launch issue. I usually hit "Print" when the platform is around 60C, unless I'm printing something I know has a serious warpage issue. By the time it's sliced and sent and the raft laid down, the platform is plen...

Re: cubify design

I've used SketchUp extensively, and while it's great at whipping up visual models, it's extremely hard to build real solid parts. That's because it's a surface modeler and as such you need to continually examine the part and 'stitch' it together. Complex solids are most difficult, if not impossible....

Re: Know what is going on?

I'm fairly new to the Afinia, but not to 3D printing in general and I agree with what has been said. I have had terrible problems on other printers with ABS warpage and inability to stick to print platforms. The perfboard for me was ridiculously easy, and also very forgiving. After perhaps 40-50 pri...

Re: Attempt at non-biased in-depth review: Afinia vs Cube

Seems like you're quite a bit quicker than me. Just booting up my Mac, launching UP software and initializing and start heating the platform is a bit over 4 minutes. And my platform never get's to 100% heated in under 10 minutes. Your UP Plus does have USB 2.0 so the load is quicker. Lots of my prin...

Re: Printing Nylon-- too hot?

Looks and sounds like the filament was printed too hot, as well as maybe some moisture in the nylon. Have you left the nylon out of the bag for a while ? It will absorb moisture in a couple days if left out. I have found that I can print nylon at 270 if it is really dry, otherwise any moisture and ...
