Win a multi-color pack of Sugru rubber for your DIY projects & repairs!

blog giveaway ends 25 January

What is Sugru?

Sugru is a super cool, air-curable rubber that you can use to improve, repair, or prototype all kinds of stuff.

It was developed over seven years by a group of product designers and material scientists lead by Jane who started the project while working on an MA in Product Design at RCA in London.

(You should really check out the Sugru story; there are photos of formulation experiments & application tests, the tales of funding struggles, and a new year’s resolution that ultimately lead to success.)

The end result is a simple, useful material chock full of great properties:
• electrically insulating so “it’s amazing for cable repairs”
• waterproof and flexible so it’s great to have along on outdoor excursions
• stable from -60°C/140°F to 180°C/360°F
• curable at air temperature so you don’t have to heat it
• is removable (with a little effort)
• sticks to almost anything & remains flexible when cured = perfect for prototypes

I’d like to try Sugru with a 3d printed mold to encase a flex circuit for a whole squishy/flexy assembly.

I would like to see how I could combine it with lasercut projects. Depending on how detailed it can get, it could give my designs some interesting texture.

I’m using laser-cut aluminum to brand a logo into foam inserts for cymbal storage. Seeing that Sugru is stable from -60°C to 180°C, I’d use Sugru for a depth-stop and handles.

I would love to use Sugru to seal the surrounds of an Arduino LCD shield, into my laser cut box. I would also love to try making some pretty button tops for my laser cut project.

I’d stick a piece on the end of my car antenna and mould it into something interesting. Decorations!

I would like to let my daughter sculpt Sugru into animal shapes and press them onto magnets for awesome homemade fridge magnets 🙂

I would like to see how well it works for moldmaking – tiny objects for scale modeling. :o)

Ergonomic grips seem like a good use.

After much use, I also notice some wear on the corners of my laser cut wood parts. Maybe bumpers for these corners?

Ooh, I would use it to make accessories for my giant 3D printed LEGO minifigs and to fill in gaps on other printed items.

I would use Sugru to mould myself some Spock-style ears! 🙂

I’d fabricate outdoor ‘street’ art sculptures and then use sugru to quickly attach it to the unsuspecting wall/roof/ladder/fence/lamppost before the authorities arrive. 🙂

The Sugru story is truly fantastic. Grounded and exciting! I also love the fact that they built their own packing machine driven by an Arduino!

I’ve been thinking about building a small radio cube for outdoor listening on the farm. Some waterproof Sugru buttons could be just the ticket!

I would use Sugru to make the steering wheel to my E36 BMW more ergonomic. My fingers are long which make it hard to grip onto the thin steering wheel comfortably. Also, the steering wheel has some random edges where I place my hands, so it pokes into them while driving.

I might be able to use it for more ergonomic pistol grips too!

One of my projects has a flex-pcb in a bracelet form. It sounds like sugru would be great for quick prototypes.

I’d use it to put soft corners on the sharp hard edges of my boxes. You’d get interesting organic shapes and some colours too. Yippee!!!

I’d use it for feet on my project enclosures. And to fix the handle on that broken pot lid. And my broken ipod cable.

I will use Sugru to construct the connection components of the electronic device I am developing for my wearable art project – it’s called “An Angel Passes”. It basically detects the “awkward silence” in a conversation. “Un ange passe” (an angel passes) is a French expression used to relax the uncomfortable atmosphere arising in such silences. I have created a digital model of a brooch-like device to be made by Ponoko’s 3D-printing. This electronic device will detect silence during the conversation among the participants. When silence is detected, the device will trigger the light on a pair of white, feathered and wearable wings to indicate that an angel is passing.

I use Sugru to repair or complete some detail of Gundam plastic model or to build some missing or custom parts for hobby model.

Hey there! Sugru is definitely a cool material; apart from decoration and practical purposes, I would mainly use it for prototyping and modelling of “small”, complex parts, like hard joinery, and to test creatively the look of 3D models before printing. Shaping by hands, could allow me to obtain more organic imperfect shapes, to be 3d scanned and later 3d-printed, resulting in unexpected industrial aesthetics. Looking forward to try it…

Fake chewing gum. Fake dog poop. Fake dog poop chewing gum.

; )

I’m sure I can come up with more practical uses, and I have a lot of projects in mind, but nothing yet that requires Sugru. 38 seconds after the contest ends, I’ll think of something…

Kelly Greene

I’ve been using Sugru since it’s beginning, so my ideas are endless. Limiting myself to just one will be difficult…but i’ll try!

I would use Sugru in the creation of my interactive games, and kinetic sculptures. Generally there are moving spheres/balls, in my works. Therefore, it would be great to have elements that are more “rubberized”, uniquely formed, and/or textured to increase the movement and bounce. Don’t really want to divulge too much more 😉

I’d like to see if sugru could be used to glue lasercut acrylic pieces together at a perfect 90 degree angle, since lasercut acrylic isnt perfectly beveled – due to angling of the laser.

I’d love to use Sugru for prototypes of kitchenware. My readers need to keep a separate kitchen of items, kind of like a kosher kitchen in order to avoid cross contamination. I’d love to be able to “mark” the gluten free products in one color of Sugru.

Stephen Waddell

I would use Sugru to add a rubberized grip to a scale model of a gun that may be included in a special edition of an upcoming indie video game.

My wife is a “killer of garden tools”and as soon as I can devise a laser cut steel design for a weed-puller that she won”t hopefully break, I plan to use Sugru to mould an ergonomic handle for it, and if I could use a glow-in-the dark type, I’d be able to find it in the garden at night!

Sugru + arduino touch sensor = soft ergonomic human computer touch interfase !

I would use it to make custom buttons with textures and dimension for a laser-cut control panel I’m working on.

I’d like to use it to create a bunch of multicolored rubber/wire/3D printed stop motion characters for the kids we work with to play with.

Sugru looks great! I would use it to customize knobs and feet to my projects and attach the 3D printed pieces to what I am customizing.

Stefan Schurr

I could fix my broken 3d Modell!

Curtis Wachs

I think it’d be awesome to laser cut some acrylic wheels, gears and other robot parts and use Sugru to create the wheel treads, bumpers and other rubberised parts.

Lasercut eyeglasses! or even 3d printed.. i’d like to use Sugru for the nose pads, the temple tips and maybe to give more strenght in some parts.
i’ve made a little image to explain what i’m thinking about and you can find it in the’s just an idea but i can’t wait to try it out with the guys from Vectorealism here in Milan!

I would use Sugru to scuplt grips for a lot of my custom made tools that need a cushioned feel.

Guillermo L.A.

I would use Sugru to make holder clips for an Ipad case box

Since I plan to lasercut a texture pattern into the panels of the enclosure for a wooden robot(arduino-based) I am making.

I’m going to use the sugru to back-fill these spaces to emphasize patterns and designs in the limbs and structure (and to insert grips and friction surfaces. (oh, and a vibration dampener on a 3d printer)

I am making a cellphone holder for my Galaxy Nexus. I would use Sugru as feet to give it steady grip on the table, and to add a splash of color to the design.

I’d use it wherever removable friction fittings are required and for grippy feet on electronics enclosures. I could even 3-D print a mold and “cast” it in the shape of a real foot.

I’d use Sugru to make some rubberized feet for a prototype I’m working on.

i think the ability to add colour texture and dimension to some of my wooden laser cut items would be amazing, especially for jewellery trees

I’d use it for quilting to provide a stable handling point when using a rotary cutter, placing the cutting guide, providing a better fit for spools on the spindles … lots of uses!

I’d like to use Sugru for three things in laser-cut electronics enclosures: assembly adhesive (for holding the cut parts together semi-permanently), custom gaskets (for holding components like LCD displays into the enclosure surface), and cable strain reliefs (when passing a cable through the enclosure wall). I’d also like to use it to mold around and bundle sets of discrete wires into cables, to clean up the sort of rats’ nest of single wires I tend to get with multiple boards.

I’d use Sugru to build a mold on a cardboard document camera that allows the iPhone to slide in and out securely rather than just sit on top.

I am working on designing a practical iPod nano watch band that is waterproof, yet slim and stylish, with an option for Bluetooth. I am making 3d printed mold, plastic first to test design, and easy to sand and make adjustments. I would use sugru as a cheap, easy, and convenient prototyping material.

I am developing a silicone housewares product and have been trying to come up with an economical way to make prototypes during my design process. So far I had only come up with 3D printing via an Objet Connex machine, but that that would be $50-150 per part. This way I can just 3D print the mold and then make as many as I need using Sugru. And a free pack would let me make even more 😉 I’m really excited about the possiblities! Thanks for sharing!

I’d create amazing + unique works of art & design out of broken mirrors, picture frames and damaged + found objects. This is just the type of material a creative hoarder like me needs in her life! x

(BTW – I just stumbled across your website – fabulous idea, guys – very revolutionary and I hope to get involved one day soon!)

I friction like to test model friction pads for at type of biker pedals, and flexible part to an power coupling.

I want to make some new pieces for my Settlers of Catan game, ive lost a few of the houses over the years.

Probably closing the gaps & correcting 3dprinted objects

I want to make collectionable figures of arquitects and desingners for my friend (frederic) birthday´s party.

Would love to get my hands on some Sugru! Would use it to make my robots more awesome.

I’d definitely use it for a acrylic piece, when I forget to include a tab and want to build it right then! I can also see it being used when using metal sheets and I want to join without welding. Fun!

Very cool – sculpted organic style bumpers for the bot would be my first use !

Cool cabinet pull knobs!
