https://SampleFilaments.com is giving out free filament samples, just pay actual shipping costs no handling.     *Ultem filaments not included   Prices across the site have been adjusted to $5 per item, the first item ordered (per customer) will be reduced to the cost of shipping (USPS first class mail generally under $3.66 to CONUS)

There isn't generally a single material that is stronger in every category than other materials or a way to apply weight into that?   

 

There are filaments that are stronger in flexural strength, tensile strength, modulus.   There are higher and lower density filaments and different fills to increase or decrease density.    

 

Do you have a specific application or application question or a specific strength/weight ratio needed?

Carbon fiber adds weight and reduces flexural and tensile modulus.     Carbon fiber only increases modulus or stiffness of materials (with the possible exception of the markforged with continuous CF infusion which is a branch of FDM)

What type of printer?  There are a few specific "bugs" in some printer firmwares that cause this. 

 

You can also try reducing the print speed to see if it changes the lines to rule out resonance and mechanical issues.

I thought it was just a video game and I was unlocking achievements! Then I found out that there are levels above the currently published levels and now I think the game is unbeatable...

We should at least get some shiny badges for unlocking new achievements?

And of course, 3D Hubs doesn't add sales tax so if we get instant orders in the US we have to increase the cost the instant an order is placed.....

@esuender try contacting Telemetry 3D http://t3d.3dhubs.link they might be able to help out and are on that side of the state somewhere.

We use 3mm boro glass from ebay and just scale the shims z height to match. Again this is the least effort or fast method not necessarily the cheapest or best for everyone.

The zero maintenance way: 

 

Step One: Print a Shim

https://www.thingiverse.com/thing:440022 (or any other z-axis shim, we have our own for internal use) 

 

Step Two: Clip the glass on with anything

https://www.amazon.com/photos/share/WBG2CopgmcCQNE1I87e3QLrVw10XImMo62hh...

 

Step Three: After about a dozen prints we can remove the clips as the bed gets adhered with PVA/Aquanet.  

 

Swapping the glass every month or two is just using a paint scraper to pull off the glass and then repeating steps 2 & 3

All of the posts have a -1 and then a 0 rating as I refresh.   Is someone downvoting the entire forum and then someone else upvoting it or is it just one person?
