If you use 3mm or 1.75mm Filament for #3DPrinting do take a look at my guide and review of SpectrumPLA material. I have also tried to cover things to look and watch out for and some simple tests you can do yourselves.

I plan to do more filament/material reviews - who would you like to see tested next, and anything else people would like me to check next time?

Enjoy a good honest review as well a constructive response from the manufacturer.

Would be awesome to see a re-review after changes are made to production process.

@Sanjay_Mortimer Agreed, they seem very keen to produce a good product that customers want and need, and that’s great. It’s certainly harder to make really good quality 3D printing food. After all that’s why we all pay quit a high price for raw plastic extruded to specific properties.

It is very good for them to try to get ahead of that, because there are a lot of good PLA suppliers out there, and if RichRap is kind of “eh” on them, that’s some bad press.

I would like to see a review of Taulman Bridge. 618 works pretty well but 645 super hard to extrude. Both shrink like crazy and soak water like crazy

i like these reviews on materials (even though i havent started printing any). but just a curious thought (maybe it will annoy some manufacturers … ) … while most hobbyist use the prints leisurely, for those who use them in more serious ways, are there anybody out there that did some kind of tests like destructive kind? eg : 1cm x 1cm x 5cm, breaks at XX kg of force? i think a few months back some peeps discovered they bought a pack of PLA but they werent PLA or something?

@3roomlab There is lots of good testing data from @Tom_Martz of Taulman3D on his nylons - check out his site.

@Tony_Olivo Real feedback is normally good for business even if it’s good or bad and they seem very keen to be a good supplier.

@Brad_Hopper I’m on the case for a Taulman Bridge review, really looking forward to testing this nylon to the limit @Tom_Martz

@Richard_Horne yes, and they addressed as much as they could on short notice. The manufacturing QA will take them more time, and may not even be in house for most suppliers. But that’s the sort of response they needed to give to not get a black eye, because why bother with a supplier that has documented quality problems, and doesn’t listen to feedback (unless it’s super cheap)
