Gel-lay informations

Recommended Posts

Hi,

I am posting here because I bought some Porolay Gel-lay http://www.formfutura.com/285mm-porolay-gellay.html and I am printing it with a UM2 extended with no modification.

I didn't find informations on this filament, only temperature given by the description (225-235 )C) and no heated bed, and I want to know your parameters and experience if someone already use it.

On my side, I try to print it at 30mm/sec speed and 50 mm/sec infill speed. My temperature is 230°C with a 0.4 mm nozzle and 0.15 mm layer height.

I saw underextrusion on the infill so i might slow down infill speed for the next print, setting it to 30mm/sec. A problem I have is that during extrusion  can hear a sound, like sizzle, and i don't know if it's normal. Maybe the Imaterial is not dry, but i hear that sound since I start using it. Before I used sylver PLA from ultimaker and I cleaned the nozzle with the atomic method so it might not be because  of dirty nozzle.

Speaking of nozzle, since I use it, there are lots of little blobs appear on the outside of the nozzle (maybe sizzle sounds is due to "projection"). Any tips for cleaning it ?

I print first a kind of sphere with the same parameters as a test piece (my goal is to print organs like liver but smaller in a first time). I put no infill and the object was very weak when I deform it. I print a cube with 20% infill to test his strenght but it is not rinsed yet.

I might post pictures later, when i will have more rinsed prints.

Please share your experience, and sorry for my very bad english :-/.

Now i have some pictures of the print.

I print a liver (scale 0.4) and this is what I get after few hours of print :

This is very rigid after printing. I put it in hot water before leaving work and after 15 hours,  I get :

When wet, this material is hightly deformable but breaks when you try to extend it.

The print takes 2 hours with parameters of the previous post. During the print, I increased temp from 230 to 235°C after few layers because of under extrusion on the infill. It solved it but it is better to lower the speed. I am now printing cylinders with different infill % and 30mm/sec definitively fix infill under extrusion at 230°C. I also disabled the heated bed and i didn't put glue stick on the plate, adhesion is still very good (I broke the bottom of the liver when I tryed to remove it from the plate with heated bed + glue :/). After few tries even without heaten bed and glue stick this is really hard to remove from the buildplate.

here a picture of the nozzle during the print.IMG_20160407_174354046_HDR.thumb.jpg.d99a62d4334ebdcdfe0ae30e5be86a69.jpg Before printing, it was a little dirty, I don't know what is happening. Do you have any ideas on how to clean it safely and why it happens?

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
