An interesting discovery awaits lovers of healthy food in Austria. Vegan meat substitutes have been around for a long time. You can’t surprise anyone with soy cutlets on supermarket shelves. After that, this year, in March, the Viennese company Revo Foods is going to produce vegan salmon on a 3D printer.

Vegan seafood with a mission

There are almost no fish of plant origin on the market, says the company owner Robin Sims. “We intend to offer an alternative to overfishing and industrial aquaculture”, says Robin.

According to the entrepreneur, a special 3D printer making for these purposes. Only natural and healthy ingredients are used in the production of vegan salmon. There are eleven of them in total. It including algae extracts from Holland, vegetable oils from Austria, and legume proteins from the Netherlands.

Revo Foods said that they are very proud of the fantastic nutritional content that is high in omega-3 and protein. This plant-based salmon contains absolutely no heavy metals, microplastics, antibiotics, or any other waste materials found in industrial aquaculture salmon.

In conclusion, the company considers the advantages of its products to be obvious since and, most importantly, it does not contain antibiotics and other health harmful substances. The trial batch was convincing in a perfectly good taste of vegan salmon. Salmon production from the printer is scheduling to begin in late summer.

A Polish manufacturer, Omni3D started in 2013 by producing cheap open-source FDM printers. Three years later, the company released the first professional 3D printer, which remains a key model in the manufacturer’s catalog – Factory 2.0.

Currently, the manufacturer is developing cooperation with industrial and scientific and educational centers, and accordingly, a professional line of 3D printers is developing. In early 2020, an amateur-grade model appeared with the Omni3D logo: Omni200.

The Omni200 3D printer can be classified in the high end of the hobbyist segment. The functionality of the device is typical for devices of this class.

The main feature of the Polish model is the presence of an all-metal body and an aluminum extruder. A closed case means that the object during the printing process is protected from sudden changes in ambient temperature, drafts, for example, and the likelihood of the appearance of defects associated with them – delamination, peeling of the model from the platform – is minimal.

In addition, a closed chamber provides a higher level of security compared to an open one. Therefore, the Omni200 can be considered as a 3D printer for a school or other educational institution.

Another quality feature is the presence of a flexible magnetic substrate. The use of a flexible backing means that the printed article is easy to remove from the cooking chamber and peel off from the backing.

The capabilities of the Omni200 3D printer are typical of the basic segment. The maximum temperature of the extruder is 260ºC and the working table is 100ºC. The dimensions of the working chamber are 200x200x200 mm. With a minimum print layer thickness of 50 microns, the accuracy will be sufficient for most projects.

Contents of delivery

The Omni200 is a factory-assembled device. It can be plugged in and used out of the box. Since all components are installed initially, only the flexible backing, instructions, and warranty card are included with the printer.

Preparation for work

Getting the Omni200 up and running is the same as setting up any desktop indoor 3D printer. There is a filament compartment on the printer under the cover. The operator installs the spool and feeds the filament through the Teflon tube into the extruder. Files are downloaded to the printer from the SD card.

Software

The manufacturer recommends using the Simplify 3D slicer with its printers. This program is designed for both experienced and novice users. The Simplify 3D interface is quite simple. An important advantage for some users will be compatibility not only with Windows but also with Linux and MacOS.

Expendable materials

The Omni200 is designed for use with common filaments with a melting point of 250 ºC or less. Plastic materials with different physical and chemical characteristics are available to the user:

• FLEX;
• PLA;
• ABS;
• Nylon.

Examples of using

One of the most common uses for FDM printers of this level is to create bright merchandise and original gifts.

Omni3D used a 3D printer to print a souvenir heart for Valentine’s Day.

The printer is also used to create tutorials, autotuning parts, and other products.

Pros and cons of the Omni200

Pros:

• All-metal printing chamber;
• Aluminum extruder;
• Reputable manufacturer.

Cons:

• Does not work with refractory plastics (from 260°C).

The Polish Omni200 printer, amateur in functionality, but quite professional in the quality of workmanship and printing, can be considered as a device for educational institutions, as well as for the manufacture of small parts of prototypes and homemade devices, or as a trial purchase to get acquainted with the quality of the brand’s products.

The device is made reliably, provides a predictably excellent work result, but the device does not stand out against the background of numerous competitors. The machine is equipped with one extruder and a standard size print chamber. The market’s typical maximum extruder temperature of 260ºC is sufficient for many educational, promotional, and DIY projects.

MaskiD face masks will be part of a package already consisting of the Neutrogena Skin 360 app and the Skin Scanner appliance that went on sale last year. A small hinged gadget, which plays the role of a kind of microscope, allows iPhone 6 and later smartphones to shoot the face in high resolution, and the application helps to select the necessary preparations for the care of individual skin areas. To make the process even more convenient, the company’s specialists decided to resort to 3D printing of individual masks, modeled according to data from the same mounted scanner.

Hydrogel masks will be selectively soaked with various cosmetics in six zones responsible for the forehead, eyes, nose, cheeks, chin and nasolabial folds: hyaluronic acid to retain moisture, vitamin B3 to improve microcirculation, girlish chamomile extract as an anti-inflammatory agent, glucosamine-stabilized for exfoliation and anti-wrinkle, vitamin C for skin lightening. 3D-printed cosmetic masks will be available in the third quarter of this year, although during the pilot program will be available only to US residents.

This is the next entry of the company into the area of additive technologies. In the years 2014 – 2017, Canon cooperated closely with 3D Systems, distributing American products on selected markets around the world. In autumn 2015, he also presented the concept of a 3D printer based on resin that has never been materialized. At the end of 2017, he unexpectedly (and silently …) withdrew from this segment, focusing on returning on his flagship solutions. Now, almost a year after he left the spatial printing, Canon returns, promising a revolution in a relatively neglected sphere …

The Japanese company intends to print ceramic details! It is to be delivered to the machine in the form of a powder and be bonded in a selective manner, based on a method similar to SLM (i.e. selective sintering of metals by a laser beam). Unfortunately, so far everything that has been shown is a handful of details – we do not know anything more about technology, machinery, or even when they would see the light of day? What Canon has been praising for so long is work with a material with a low shrinkage. The corporation claims that just as existing incremental technologies that use ceramics at work (and the resin that is its carrier) during post-processing shrink by approx. 20%, in the case of its method the contraction is symbolic and amounts to less than 0.8% . As an example, give the following detail with a diameter of 19 mm.

Ceramics is a very desirable consumable material, but few manufacturers have managed to develop techniques able to tame it. Selected companies producing photopolymer 3D printers offer ceramic and resin composites, and attempts are made to press ceramic materials through the heads in a derivative process to FDM (i.e. 3D printing from plastic). Big promise is also 3D printing with the so-called “Liquid ceramics” (i.e. ceramic nanoparticles embedded in drops of resin) developed by the Israel XJet, which unfortunately has not yet hit the market.

When it comes to Canon, just like the company has the ability to develop and implement such technology, the way it presents itself is somewhat fascinating … As vividly reminiscent of the actions of October 2015 when the renders of the machine that was supposed to coil the market were presented. At the moment, we do not know anything except that the concern “is working on something crucial” – we do not know the deadlines, technological assumptions, real possibilities of this method?

Let’s hope that what we are now dealing with is the introduction to a well-thought-out and complex promotional campaign, and not, for example, the “innovative projects of the future”, to prepare the ground for upcoming publications of periodic financial results …
