The last thing you want is me looking over your shoulder but it might be useful for the dartboard.
You and I may well approach robot building from different directions but diversity of design and construction is one of the best parts this hobby of ours.

Hello,

Inspired by your awesome builds I finally gave up and bought a 3D printer 😵. Antweight building seems to step up another level with 3D printing. It’s not arming untill June. However it comes with no filiment except a small sample. On the website a spool is £21 for 1KG!!! Then on eBay it’s £10... will the quality be a notable difference. Should I be investing in premium filament? Or is it really not worth the extra pounds.

Thanks for your time.

Maybe ask someone in your local Hackspace.

Our 3d printer guru chap gets the materials, I think we buy bulk PLA. I will check what filament the "Drax" robot shell was made with.

I think it is worth going with a reputable supplier even for the cheap stuff, in my opinion, because at least you'll get consistency. The problem with the ebay / no-name filaments is that they might be great - but perhaps the next batch will be awful.

Also I've heard stories about the 2.85mm nominal filaments jamming because they make them too wide. Good suppliers make them very close to 2.85, but some dodgy ebay stuff is over 3mm, which is typically about when the machine jams. It's not always the same width through the whole reel.

Great choice on entering the world of 3D printing! You wont regret it :)
Having worked the last 7 years in a 3D printing and model making business - I have gone through lots of printers and lots of materials from the £10 a kilo to the £500+ a kilo :lol: .
The bottom line is - if you value your time at anything; It's worth spending on better filament.

When you consider £25 for a kg. And an entire chassis for an antweight will use perhaps, 20-30g of filament. You are looking at 75p a chassis or 40p a chassis if you go the most budget route. Worth spending those extra pennies ;)

More expensive filament is more dimensionally accurate (reliable prints, less chance of a jam) , generally has better additives for lubrication. (more important with bowden tube FDM printers, but still important for others), better layer adhesion (stronger in a fight) and will generally cause you much less headache and failed prints, from my experience.
And there is nothing more annoying than coming back 8 hours later to a mess of wasted time and filament! :lol: 35p is worth that ten times over!

I would recommend Rigid Ink

Use this link you get £5 off first purchase. https://goo.gl/vKabzV
https://rigid.ink/products/abs-2-85-mm- ... -tolerance
They also do lots of small samples which you can trial. As well as exotic materials like nylon, polycarbonate or carbon fiber. (sorta)

Other good ones i have used is the Monsterfil brand.

Store the roll of filament in an airtight box like this

With some silica gel to keep the moisture away. And out of direct sunlight.
Then it will last for a long time :D
