At the end of 2016 we had a Massivit1800 3D printer from Massivit3D, which is unique in its technical characteristics. After six months of work and a number of successful orders we are very pleased to share the results with the 3DToday community.
Background: Massivit3D was established in Israel in 2013 by specialists who had previously worked for world-renowned companies such as Hewlett-Packard, Stratasys and Scitex Vision Ltd. In its first years of operation, the company has installed and put into operation 25 Massivit 1800 3D printers (https://top3dshop.com/product/massivit-1800-pro-3d-printer) around the world and the number of orders is growing steadily.
So what exactly is a Massivit1800 3D printer? It is a huge machine with a working area of 1.2 x 1.5 x 1.8 m. Unlike previously known 3D printers for 3D printing large objects, the main advantage of the Massivit1800 3D printer is speed. The development of Massivit3D specialists allows you to print large-scale products with a speed of 35 cm per hour along the Z-axis (in height).
Massivit3D independently developed and patented a special 3D printing technology called Gel Dispensed Printing (GDP). The GDP process is based on the combination of a highly viscous, unique photopolymer gel, and an optimized arrangement of supporting structures.
GDP is similar in principle to FDM systems, but with GDP a nozzle extrudes a liquid photosensitive material which is cured by UV lamps above the printheads. Thus, layering and curing occurs very quickly. Due to the curing speed of the Massivit1800 printer, there is no need to use supports for horizontal surfaces, which saves material and time and was not previously possible with similar 3D printing technologies.
The outstanding advantage of the Massivit1800 3D printer is the presence of two independent print heads, so that two different products or two parts of the same object can be printed simultaneously within the workspace, allowing you to create shapes over 3 meters in size for subsequent bonding.
In addition to the aforementioned advantages, Massivit has another and no less important one – the simplicity of the post-processing. Cured in layers dimengel is perfectly amenable to sanding and has excellent susceptibility to painting and varnishing.
Of the projects that we realized in the last six months, I would like to share the layout of a kinetic helicopter for a state enterprise. This layout was ordered for the international exhibition HeliRussia.
Our main project recently was the preparation for the international exhibition EXPO2017 in Astana, the capital of Kazakhstan. We took part in the production of 12 stands for the pavilion “Energy Best Practices Area”. Thanks to Massivit, we were able to significantly speed up work on some of those that required large-scale printing
For example, for ABB Solar Impulse, we printed a globe for the booth. The size of the globe was 60 cm in
diameter, printing time 5 hours, surface preparation and painting 3 days.
For Andrytz Hydro we printed the blades of wind turbines and fish (The size of turbines 1,5m, 2,5m, 3,5m, 12 fish of size from 25cm to 50cm, time of printing all elements 3 days, preparation of the surface and painting 5 days)
Also we printed on Massivit blades for stand Rainmaker.
For the Global Hymalayan Expedition booth we created a 4×1 m model of the Himalayan Mountains. We completed this job in five weeks, of which a week was spent printing, two weeks on filling with two-part polyurethane, gluing, sanding, puttying, and another two weeks on painstakingly painting the mountain massif. We printed the structures in plaster on a Projet660.
