Mola Structural Kit 4 - Practical Structural & Architectural Modeling for real-life analysis

Welcome to the world of arches and shell structures. Mola 4 expands the Mola Structural System by introducing folding techniques and origami principles to demonstrate how form affects structural efficiency. 

Expanded versatility and customization with curved bars to simulate arches, origami-inspired shell structures, and exclusive new components allow for unprecedented building and customizable possibilities.

Probably the most realistic construction toy in the market today, Mola is an interactive physical model that simulates the behavior of architectural structures. Including a set of modular pieces easily combinable with magnetic assemblers, with Mola you can translate paper plans into reliable 3D scale models that will obey the laws of nature just like a real life building would.

Mola Structural Kit 4 works independently from Mola Structural Kit 1, Mola Structural Kit 2, Mola Structural Kit 3 with which you could put it together to create many other structures. None of these models require prior technical knowledge for you to start studying structures, plus it is easy to assemble and use by magnetic grip, and includes very precise instructions and examples in the Manual Book included. It is made simple and instinctive and is applicable to both professionals and students, as well as anyone interested in the subject, which has made it the most supported project on Kickstarter

Price includes Brazilian duties and importation to EU.

  WARNING  

This product contains small magnets and it's NOT A TOY. As such, it is NOT RECOMMENDED FOR CHILDREN UNDER 14 years old.

Swallowed magnets can cause damage to internal organs and can result in SERIOUS INJURIES or DEATH;

. Keep away from ALL children;
. Be aware of dropped or separated magnets;
. Keep away from mouth and nose;

Seek immediate medical attention if magnet(s) were swallowed or inhaled.

Contains 145 pieces along + a comprehensive Book/Manual. With this set, you can build all the examples provided and explore over 100 different structural arrangements.

The Mola 4 Book/Manual is a bilingual practical guide (Portuguese/English) that provides a comprehensive explanation of components, and assembly tips. This guide walks you through how to build and analyze different structural systems, making it an essential resource for maximizing the potential of your Mola Kit.

In addition to some pieces you may know from previous sets, Mola 4 features an entirely new set of elements designed specifically for creating arches and shell structures:

• Arch bars: Mola 4's new curved spring is designed specifically to simulate arches.

• Foldable origami sheets: To simulate them, we're adding pre-marked sheets in various shapes to simplify the building process—no origami expertise is needed.

• Surface connection: This specially designed connection enables these assemblies by attaching the sheets to a magnet.

Some of the structures presented in the manual:

1. Arches
2. Arch support reactions
3. Association of continuous arches (vaults)
4. Association of radial arches (domes)
5. Shell structures
6. Folds in structural efficiency
7. Cantilevered shell structure
8. Pavilions with shell structures

This qualitative analysis tool can be used as a resource to conventional methods of study, conception and verification of structures. If you are studying Civil Engineering or Structural Behavior, or are an Architect, this is a great way of answering many of the questions that are hard to picture only on paper or theory or through elaborate computer designs.
