New material for flexy object extrude by happynew3d Apr 20, 2013

Description

For a complete flexy rubber object , Urethane wire can be used to extrude object with better resolution and less trouble. I used 3mm red color, hot end 215° and bed 80°.
Material is food certified !! You can print seal, oring, tracking weels , footprint , piston for air compression, thin flex membrane more and more....
you can find the urethane wire at RS catalog item number 2596480
red and green color. Fast delivery ( italian site has 30% less cost)

same catalogue you can find orange , red, green and transparent urethane 3mm

I have a wades extruder and hot end as per ebay 281121988525.
Had no problem at all extruding. Please remember that if your last extrusion was with ABS , you need to go high with temperature till all the abs is extruded to clean the extrusion channel than reduce the temperature to the urethane 215°. Hope it helps

I am using a wades' extruder with a J head nozzle, but am having trouble getting it to extrude consistently. I slows down and eventually stops extruding. I've tried several different temps 190 - 245, maybe I'm extruding too fast or too slow.. The gears just keep pushing it through though. What kind of extruder are you using? Do you have a like to in here on Thingiverse?

Anyone find a reasonably-priced supplier for this stuff? RS, Fenner Drives, Misumi - they're all $35+ for <= 30m. That's 3-4x the price of good PLA.

Doesn't work with the RapMan unfortunately :-(
The material gets compressed and gets stuck immediately between the worm wheel and the extruder base.

happynew3d on May 28, 2013 said:

It can work with extruder close to the worm wheel only

What would this thread be like in a Bowden tube extruder?

happynew3d on Apr 24, 2013 said:

I think it is not working on a bowden extruder as the long delay in push pull as per the soft material. Today I printed a membrane and valve plate at 0.1 resolution and 0,25 total thickness. Works great. I modified my hotbed so could go down to 75° instead 110

tom10122 on Apr 21, 2013 said:

Is this more like PLA or ABS? is a hotbed needed?

happynew3d on Apr 21, 2013 said:

Yes , hotbed is a must. I first started with 80° but after the first slice , the plastic peel off. So went up to 110° at least for the first two slices. After this you can go down to 50 ° with no problem. This material is soft but slices are quite impossible to disconnect. It is not brittle like PLA , it is soft but very resistent. You can stretch without strap.

This site has a range of colours & sizes (2mm smallest tho)

Not sure what the different Shore ratings will do.

happynew3d on Apr 21, 2013 said:

Yes it seems polyurethane is commonly used for belt. You can find from china supplier . I pointed to RS catalogue for the worldwide and standar availability. may be it is a bit more costly ( not at all) but a really good service. Took me two day to have it at home

MichaelAtOz on Apr 20, 2013 said:

From Wikipedia, Shore A values

70 Automotive tire tread
78 Soft wheels of rollerskates and skateboard
70-90 Hydraulic O-ring
98 Hard wheels of rollerskates and skateboard

£33 for 30m is well out of my price range. looks good though

happynew3d on Apr 20, 2013 said:

there are 5mt size for less price. Different color can be lower price

happynew3d on Apr 20, 2013 said:

I payed 23 euro + 6 euro shipping. Don't know why but in italian site it cost less. Shipped from Uk anyway....... When you need a flexy object 33£ is not so much.

kwalus on Apr 20, 2013 said:

do you know if it is available anywhere in 1.75mm?

happynew3d on May 18, 2013 said:

ok today I could see a supplier that had urethane 1.75mm you can ask to: [email protected]

happynew3d on Apr 20, 2013 said:

but you could buy another extruder and resize it 1.75. May be new business in progress . You'd be the only one 1.75 producer..

happynew3d on Apr 20, 2013 said:

I know there is 2mm. sorry think 1.75 is outranged

koolhandkc on Apr 20, 2013 said:

Excellent! I think it's awesome that people are branching out on using different materials. I have quite a few projects that could use some flexible/compression parts...thank you for this.

happynew3d on Apr 20, 2013 said:

you are welcome!! this material is much better than PLA . Resolution impressed me so much and is faster in cooling. Have fun!
