What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

New quadruple power in 3D printing

  • Four colors 
  • Four materials
  • Four nozzle sizes
  • Ooze- and drip-free
  • Excellent surfaces
  • More efficiency during the printing process – considerably less production time

The Multex4Move – new print-head technology

Der Multex4Move - die neue Druckkopf-Technologie - Kampagnentext deutsch

The Multex4Move provides for distinct improvements on several levels that open up completely new dimensions in the field of 3D printing. Due to the clever design, oozing (dripping during multiple hotend printing) is finally a thing of the past. We achieve this by only allowing our active nozzle to be in direct contact with the model.

In this campaign you can order either a Multex4Move extruder by itself, or together with proven Multirap M420 3D-Printer (as construction kit).

The inactive nozzles are retracted, effectively sealed and cleaned before each new use. Color mixing and oozing is fully a thing of the past.

Multex4Move Hotends

The four hotends have separate heating elements, temperature regulators and filament feeds and are therefore the basis for more flexibility and a considerably higher level of performance, e.g. in the case of complex printed parts. Therefore, we not only achieve more variability, but also better printing quality and diversity that have not been possible up until now – plus an extreme reduction in printing time. In this way, it is possible to print quick and stable inner structures with large nozzle diameters and flow rates. It is also possible to achieve fine surfaces by printing with a small diameter nozzle during the same print run; all of that is completely ooze-free!

This technology provides significant advantages when using water-soluble filament for supporting structures. The separation is clear and clean; the pulping process takes place trouble-free and provides for high-quality results.

The number “4” in Multex4Move stands for four nozzles that are used in parallel within a single print run. With Multex2Move, the version with two print heads, Multec has already reached series-production readiness; the enhanced version with four print heads is almost ready for production. Both print heads, Multex2Move and Multex4Move, have the same nozzle automation system and use the same cleaning process. Both functions have been tested in successful series tests for Multex2Move, and both are already ready for production in the case of Multex4Move. In the case of Multex2Move, two powerful drive steppers with steel planetary gear and 5:1-transmission provide for high-torque and slip-free feeding. The feed mechanism has been tried and tested by Multec since 2014, is fail-safe and operates the Multex2Move via a Bowden connection.

Due to an extremely strong feed stepper motor, the automatic feed system used for Multex4Move is also capable of transporting four filaments independently of one another.

This feed automation system has been tested on a technical level and is extremely strong, just as in the preceding models.

The fine tuning for serial development is currently taking place in two areas; firstly in the adaptation of software, and secondly in the optimization of weight and size.

As a result of this, oozing shields and cooling of nozzles when printing will no longer be necessary. No more need for elaborate software adaptations just to prevent oozing.

The additional flexibility gained during the printing process allows for unprecedented possibilities - It is even possible to upgrade the Multex2Move to a Multex4Move. This is yet another advantage due to the freedom and flexibility of this design.

The hotends that come installed are tried and tested Multec hotends which been optimized for great printing results on the new Multex4Move with active cooling and optimized cooling elements. The nozzles can be changed quickly and easily and are available in various sizes.

Software

At the moment the Multex4Move and Multex2Move can be fully utilized with slicers that support multiple materials. At Multec we generally use Simplify3D as a slicer due to specific advantages it offers for printing with multiple materials. It allows us to utilize a parameter for the “next” X/Y” coordinate so that all hotends can be covered when the printer is in motion and not printing (Called “free travel” in Simplify3D). Using the Multex2Move or the Multex4Move in conjunction with the free printing action, you can avoid stringing between printed areas. This means that with the Multex4Move you can avoid stringing problems in single material prints as well as prints using multiple materials.  

At the moment, one of our current tasks is to build a similar feature directly into the firmware. This would add the capability of closing the hotends during “free travel” independant of the slicer being used.

Cooperation with science and research

Our development department is in close contact with numerous universities throughout Germany that are closely associated with the development of the future of 3D printing.

The intensive cooperation and collaboration with leading scientists provides for important momentum within the scope of our own development work, and paves the path for extraordinary and innovative solutions.

This not only applies to developments like the new Multex4Move, but also for basic materials, which we have continuously worked to improve.

As an example, we would like to mention our food safe, high impact strength and high temperature PLA-HT filament.

In the end, we achieve considerably better results in all areas of the manufacturing process, whether it be quicker printing times, smoother services or – one of the main advantages of Multex4Move – precise material separation.

Multec – established 3D printer manufacturer

For many years, the 3D printer series, MULTIRAP, has stood for durable, precise and powerful 3D printers with perfectly adapted print heads that are optimized for the field of printing technology. From the beginning, the innovative power of MULTEC has been concentrated on the core of 3D printing, the extruder. After many years of experience and meticulous development work, production of the first ooze-free quad extruder has been made a reality on a worldwide level.

With this product, MULTEC is setting new benchmarks and standards that will considerably enhance the range of applications of 3D printing. This new technology not only makes the production of complex products possible, but it also provides for a massive increase in quality. Competence, expertise and high quality standards are not a matter of chance. With over 1000 printers sold, we not only possess a great wealth of experience, due to our close relationship with our customers, but we also know exactly what is being demanded in the market and where problems and opportunities lie. Our commitment and expertise are not only limited to printers and extruders, but also extend to crucial improvements in the field of filament development.

Our MULTEC PLA-HT Filament is an example of a high quality, unbreakable and high temperature resistant filament deriving from our development, currently available under “Awards” via KICKSTARTER.

MULTEC – the manufacturing concept

The focus of what we do lies in the design and further development of components for 3D printing. A key role in technology leadership is the objective. Nevertheless, we have a small in-house production area, in which we offer and handle small scale production runs.

For greater quantities and production volumes, we rely on an established and close relationship with local manufacturing partners.. Within the scope of our production, we rely and focus on “Made in Germany” for products ranging from individual components all the way to high performance industrial 3D printers

All manufacturing processes are subject to high-precision German safety standards, guidelines and certifications. Close proximity to the production site and clear, regular communication with our partners and customers are important us. Only in this way can we achieve the efficiency and high quality standards that our customers expect of us. Our focus is on the absolute reliability and durability of all components.

For consistency and reliability, we also maintain a constant supply of assorted spare parts on hand.

MULTEC stands for quality and precision - without compromise. Our target markets are currently in Europe and the USA, where we have an efficient logistics partner.

You can contact him directly for questions: patrick.hilderbrand@multec.de

In addition, our American employee, Patrick Hilderbrand, is also available to our customers abroad as a direct point of contact.

The proximity to our customers is important to us, whether they be located in Europe or the USA. With Kickstarter to launch us into the market, we are now on the threshold of being ready for serial production.

For this last step, as well as for the market launch, we are banking on the encouragement and the support of the Kickstarter community. Be among the first to use this technology and benefit from our early-bird offers. Help revolutionize the 3D printing market by taking advantage of the ability to use tomorrow’s technology today!

Risks and challenges

Multex4Move and Multex2Move
Both print heads with automatic nozzles, hotend optimization and cleaning functionality have been successfully tested under continuous printing conditions and are now ready for production.

The 4x-filament feeder currently exists as a functional unit in a pre-production form. We are now optimizing it for production in terms of weight, size and accessibility. The functionality of any optimizations must be proven, which means there is a small risk that this could take longer than planned. However, we have adjusted our delivery times to take this into account. Parallel to this, the software (firmware) and the electronics are also being optimized.

We are working out the best software settings to support our backers who use either freeware or professional slicers, in order to quickly integrate the new functions available with this product.

The Challenge - four print heads
Our tests and development are nearing completion. A printing process, with four print heads in use, using different materials and different nozzle sizes.

Risks
We are in the phase in which all components have been tested and optimized and made compatible for the printing process. Since the basic functions and printability have been developed over many print tests and optimizations, the remaining risks in the areas of software and fine-tuning of the 4x-filament feed are manageable. In the course of the campaign, we will present the production solution. Further topics in development are: firmware and electronics optimization, as well as software / print parameter adjustments.

So therefore... KICKSTARTER
The Kickstarter campaign is designed to help us achieve the final development and breakthrough of our new printing technology. A groundbreaking project and a huge step into the future of 3D printing.
