It has been almost a year since the previous challenge dedicated for future vehicles took place on our platform. We still remember the marvelous designs, which were highlighted as the best ones, so it was no brainer to decide organising a new challenge based on the similar topic.

We believe that this broad futuristic topic itself will inspire you! Do not limit yourself to the conventional means of transport, let’s explore all possible methods of travelling – from electric rickshaws, to two-wheeled part drone, part car monsters or even flying trams. Any computer-generated 3D model of a fantasy concept vehicle is welcome, as we are inviting you to take part in creation of the vehicles of tomorrow.

You will have a chance to win amazing prizes from our sponsors: DOSCH 3D: Splash Effects packages by Dosch Design, software licenses by Moi3d, one-year memberships by Game Textures, three-month subscription by The Gnomon Workshop and PixPlant software full license for Windows or Mac OS X by PixPlant.

It is evident that 3D printing has place in schools and will continue to have a significant impact and value for education. That's why we decided to contribute to the worldwide initiative and organize an educational project called "History Through 3D Printing". The expected outcomes will be grouped in two model categories: 1. Miniatures / busts of US presidents 2. Miniatures representing architectural styles.

How will it work? You can find the list of required models below. Every week it will be updated to demonstrate, which models are still required to complete the collection. At the end of the challenge, the best models will be awarded. Even if your model is not among the winners, be sure to check the final collection - we may still feature it if it's got us charmed.

We are doing this because we believe that our community is strong enough to initiate such a movement and help the young generation become better aware of 3D printing and its potential to be used in the process of learning. This idea is supported by amazing partners: 3D Systems offering the 3D printer for the winner of this challenge and Colorfabb!

9th of September was the big day for all the Apple product lovers - Iphone 6s was finally announced. We believe there's no need to talk much about the specifications of the new phone model as almost all of the fans were following each and every word in the press,right?

Knowing the fact that September 25th will be another big day for those who pre-ordered new model of iPhone as well as for those waiting to buy it in a store, we decided to organize 3D Print Apple 6s Accessories challenge. We believe it can help those who are starting to search for the original elements for their upcoming and exciting purchases. At the same time you will have a possibility to increase your sales, get exposure and prizes from Prototypster and CGTrader!

So, turn on your creativity and design exclusive phone cases, stands or any type of accessory that comes to your mind! Here you can find the technical specifications of iPhone 6s: http://www.apple.com/iphone-6s/specs/

There's a visible trend in our community - it seems that you are crazy about game-ready model challenges. We appreciate that. Really. A lot. That's why we decided to cheer you up before the beginning of autumn by launching CG Game Character challenge.

You will have a chance to win amazing prizes from our sponsors: Render fee Rayvision, Substance Live, Substance Painter or Substance Designer licenses by Allegorithmic, Memberships by CG Cookie, Single licenses by Topogun, store credits by Daz3D, Weekly rentals of a GPU server by Ultrarender and additional prizes by CGTrader.

So, it's time to kick ass and chew bubble gum, and we hope you're all out of gum!

Is there life on Mars or are we alone in the entire universe? There are thousands of UFO stories and aliens being spotted around the world every day... are all of them pure lies? And what about the future? Will those creatures (if they exist?!) live among us and become part of our society?

These questions have been tackled in various sci-fi movies, games and books about alien attacks and invasions. However, fantasy films aren't the only factors making us doubt our fact-based reality. "I think we're going to have strong indications of life beyond Earth within a decade, and I think we're going to have definitive evidence within 20 to 30 years," says NASA chief scientist Ellen Stofan and - you will agree - he is pretty convincing. Or at least a little bit more realistic.

Inspired by the numerous sources of alien-focused discussions, we got curious to know how CG designers imagine aliens and interpret this challenge theme. Its title indicates what we're looking for: show us fictional creatures from the planets existing in space (or inside your head, for that matter), design their spaceships or other spacecraft helping them to travel from one planet to another, and construct their living environment in 3D. Let's inject some 3D fantasies into this alien story.

Surprise us and our sponsors Cheetah3D, LightWave 3D Group and RebusFarm by creating totally new worlds with living yet undiscovered creatures!

At least once in your life there should have been a situation when one or another part of your gadget - smartphone adapter, toaster locker or whatever - had got broken. You are getting desperate and disappointed asking yourself: "Where on Earth could I find this small piece?" Usually the answer is: "Nowhere, my dear. You should probably go and grab a new toaster or adapter" as it could be really hard to come by with a tiny component needed. Doesn't sound exciting, does it?

One of the most practical ways to use 3D printing technology is spare parts. So, this brand new challenge is a call for makers, DYI designer communities, 3D printing professionals and enthusiasts! Think about the items, gadgets or whatever what can have breakable parts and design them. For the author of the best model our amazing challenge sponsor Leapfrog 3D printers company is ready to give away the fascinating and extremely motivating prize - Leapfrog Creatr HS printer worth $2500! Imagine the ability to print dozens of spare parts for your friends and yourself!

Maybe this challenge will help someone to get the spare part needed? We're giving you a hint: it is said that some previous generation Apple adapter is known for stopping working after some time due to its design... Here's only one idea, but we believe dozens of them spin in your head. Let those ideas turn into 3D printable objects! CGTrader and Leapfrog 3D printers company will work on boosting your motivation for that!

Make it useful, make it printable and make it work!

Can you imagine your life without a soft and comfortable bed to lay after an extremely intensive day? What place would you choose to eat at if there were no chairs, sofas and tables invented?
