FixIts: User-Moldable Plastic for DIY Repair, Developed by Chris Lefteri

Comes in stick form, dries harder than Sugru

By Rain Noe - July 2, 2018

Chris Lefteri, the materials designer who literally wrote the book on the subject, has cooked up a new plastics-based concoction meant to be used for DIY repairs. Called FixIts, Lefteri's blend of polymer-based herbs and spices comes in stick form and is user-moldable:

"FixIts are incredibly tough and made to last," says the Kickstarter campaign. "Once hardened, they can be drilled into, hammered into, screwed into, sanded down or cut to size." In terms of texture, "Once it has cooled down it forms a hard plastic that is similar to nylon in strength." That ought be appealing for folks looking to outgrow Sugru.

Each stick is 150mm x 16mm x 4mm, and a three-pack will set you back $7. They've already been successfully Kickstarted, and there's 24 days left to pledge.

Im having a moral and ethical dilemma: the campaign never straight out claims to have invented this plastic, but only goes as far as saying “conceived by chris lefteri”, which perhaps is meant to refer to the form factor, but certainly will confuse potential pledgers. In fact it seems that @rain noe understood that Chris engineered this new material.
-is Chris cheating the public by not disclosing that his only differentiator is shaping it like a stick? (And in fact, if you read te comments on ks someone else in uk have been selling it in card forms)
-would you agree that many who Pledged would not have done so had they know that this product is available in pellets for a fraction of the cost?
-does that in any way affect your opinion on chris or the honesty of the campaign?
- if I pledge 1$ just so I can go on the comments and list all the ploydoughs, polymorphs etc. Available right bow for cheaper: does that make me a d*ck?

You can buy a pound for 16$ on amazon under many brands, in pellet form so you can use as much as you want, and some brands include a collection of master-batch colors so u can color it any way u want, including marbling or other effects.
Sugru is a company selling their marketing, not their product, which is way inferior and many times more expensive.
Now these bozo is trying to pull a fast one

From Wikipedia:

PCL also has many applications in the hobbyist market where it is known as Plastimake, NiftyFix, Protoplastic, InstaMorph, Polymorph, Shapelock, ReMoldables, Plastdude or TechTack. It has physical properties of a very tough, nylon-like plastic that softens to a putty-like consistency at only 60 °C, easily achieved by immersing in hot water.[7] PCL's specific heat and conductivity are low enough that it is not hard to handle by hand at this temperature. This makes it ideal for small-scale modeling, part fabrication, repair of plastic objects, and rapid prototyping where heat resistance is not needed. Though softened PCL readily sticks to many other plastics when at higher temperature, if the surface is cooled, the stickiness can be minimized while still leaving the mass pliable.

This is polycaprolactone. It's already widely and cheaply available in pellet form.

Polycaprolactone. It's already widely available online. You can get it super cheap in pellet form.

The lack of disclosure on the Kickstarter campaign strikes me as very dishonest.
