The flip of the millennium led to many modifications. Whereas our aeroplanes remained within the sky regardless of fears of the Y2K bug, developments in expertise would see the rise of the web, and with it issues like social media and cell apps. Shopping for music would grow to be a factor of the previous, as would our tendency to learn phrases like these in print publications. It additionally coincided with the launch of color 3D printing, that means speedy prototypers would quickly have an alternative choice to constructing components layer-by-layer in monochrome.
Pioneering that individual motion was Z Corp. By the point the corporate had been acquired by 3D Programs 12 years later, its color 3D printing expertise was enabling the likes of LAIKA to start out making use of color throughout the construct slightly than portray components in post-production. However LAIKA’s Director of Fast Prototyping Brian McLean would inform TCT in 2018 that, even by the point it was engaged on Paranorman (2012), they discovered color 3D printing expertise to be inconsistent ‘from print to print.’ It wasn’t simply the customers who had reservations concerning the expertise. RIZE CTO Eugene Giller labored as a Senior R&D Chemist at Z Corp between 2005-2010, and he too had been unhappy with the standard of the components Z Corp’s color expertise would output.
“I at all times thought it must be a expertise that would present a totally purposeful color half, not simply kind,” the RIZE founder instructed TCT. “For me, it was all about energy.”
At the moment, there are a bunch of corporations supplying color 3D printers to market, together with RIZE, Stratasys, HP and Mimaki. The latter launched the 3DUJ-553 platform with its capability to print ‘greater than 10 million colors’ in 2018 and adopted it up with the smaller format 3DUJ-2207 system in 2020. Its bigger 3DUJ-553 machine boasts a construct quantity of 500 x 500 x 300 mm andt makes use of a UV-curable inkjet course of to print components in full color. White and clear inks may also be blended with colors so as to add transparency, whereas water-soluble supplies allow post-processing instances of simply a few minutes.
Dutch service supplier Marketiger was among the many first customers of Mimaki’s color 3D printing expertise. As of late 2019, the corporate was producing as much as 20,000 customized collectible figurines yearly, although a second 3DUJ-553 was put in in early 2020. With the machine’s automated cleansing sequence and queuing capabilities, Marketiger is ready to print at as much as 72 hours in a row with out touching the printer, however typically sticks to in a single day print jobs.
Due to the character of its core enterprise – customized collectible figurines based mostly on 3D scans of individuals – the corporate targets 100% yield. To make sure everybody who scans themselves will get a 3D printed full color mannequin, Marketiger solely begins manufacturing fashions as soon as it has confirmed the standard of the scans and modifying of the fashions. However as soon as the print button is hit at Marketiger, it barely stops.
“My firm is constructed on this machine working 24/7,” Marketiger Director Maikel de Wit instructed TCT at Formnext 2019. “It causes some points as a result of it’s a brand new expertise, however we’re in a position to get this machine above 80% utilisation on a 24/7 foundation.”
Evidently, a lot progress has been made in color 3D printing over time. With the inaccuracies and supposed brittleness of early color 3D printed components, constructing a enterprise across the expertise as Marketiger has with Mimaki’s tech was hardly doable. But, the businesses bringing the expertise to market know there’s nonetheless extra to be performed.
Giller has at all times been of that mindset. He based RIZE, partly, as a result of he wasn’t proud of the standard of elements coming off Z Corp printers. But, he has at all times had religion within the potential of color 3D printing. In beginning RIZE, Giller has aimed to ship a printer that may function in any surroundings to ship purposeful components in full color that require minimal post-processing. His reply is XRIZE, which makes use of the patented Augmented Materials Deposition expertise to construct components by jetting a formulated launch agent between layers of extruded supplies. Whereas the extrusion course of permits carbon composites to be printed, the jetting facet of the method permits the voxel-level utility of full-colour graphics.
For RIZE, the potential functions transcend prototyping and collectible figurines. Multi-coloured medical fashions – as we detailed in quantity 29 difficulty 2 of TCT Journal – is a key play for this expertise, as are jigs and fixtures. For manufacturing support functions, the usage of high-performance polymers and composites guarantee components can face up to the manufacturing unit ground, whereas color can be utilized to point when a component wants changing, as with the manufacturing support pictured on the prime of the web page. These are simply among the methods RIZE’s prospects are utilizing its full-colour expertise, and so they’re not shy of telling the Boston-based agency how they will nonetheless enhance.
“They need new supplies,” Giller says. “And that’s why we’re working actually arduous to introduce a brand new set of supplies. They’re actually proud of [the current materials] proper now, however there are a subset of consumers that actually need components to go within automobiles the place they’re uncovered to grease. In addition they ask for elastomeric supplies.”
Consequently, RIZE is working so as to add such merchandise to the and Rizium One, Rizium GF (Glass Stuffed), and Rizium Carbon supplies it already affords. Unsurprisingly, the corporate will not be alone in constructing out its color 3D printing portfolio to fulfill rising buyer demand.
Stratasys has been prolific in that regard. It now affords greater than half a dozen full-colour 3D printing techniques in its J Sequence portfolio, with some designed particularly for the dental and medical markets. In June, it launched the J55 Prime, an office-friendly full-colour system that operates as quietly as a fridge (lower than 53 DB), alongside a variety of latest purposeful supplies. The enlargement of fabric choices, regardless of the wealth of machine choices, is seen as the first method to nurture the corporate’s color printing providing.
According to the J55 Prime, Stratasys rolled out the Elastico Clear and Elastico Black rubber-like supplies, the Vero ContactClear translucent Biocompatible materials for extended pores and skin or bodily contact, Digital ABS Ivory for prime influence designs, and ultra-opaque colors enabled by the VeroUltra household. Different supplies within the Stratasys color portfolio embrace the versatile VeroFlex and the versatile VeroVivid.
With developments additionally being made with the 3MF file format and Stratasys aligning with KeyShot, the corporate is assured in its capability to ship the main points and aesthetics that any designer might need, however like RIZE is continuous to push on the efficiency facet by ongoing supplies improvement.
“Relating to mechanical properties, that is nonetheless within the works,” says Zehavit Reisin, Stratasys Vice President, Head of Supplies Enterprise and Design Section, ROW. “Once we talk about PolyJet supplies, it’s about acrylic-based photopolymers and so they behave in another way versus, let’s say, thermoplastics. Their warmth situations or their dimensional stability is topic to vary should you put the half beneath stress, beneath warmth, beneath aggressive environmental situations and that’s the place sturdiness is questionable. That’s the place [there is a question mark around] manufacturing finish use components with PolyJet. However we’re persevering with to work very arduous on bettering the fabric properties of what you see in the present day on the J Sequence, that means the colors, the transparency, the mechanical and thermal properties are higher to face up to the required environmental situations.”
As color 3D printing establishes itself within the medical and prototyping sectors, there’s now a look in direction of different alternatives. For a surgeon or a designer, the advantages of color 3D printing are apparent, however in different markets the uptake is slower. That will not be an issue since there’ll at all times be medical procedures to hold out and components to design and redesign, however on this trade, there’s at all times an urge for food to push the boundaries. And Giller is optimistic concerning the influence full-colour 3D printing can have shifting ahead.
“The way in which I give it some thought, all of us have color TVs, and no one needs to return to black and white,” says Giller. “However I’m sufficiently old, I did have a black and white TV and I keep in mind some individuals saying, ‘I don’t want color, TV is an artwork’, and now, nobody thinks this manner. If we will get it to a [lower] worth level, I feel individuals would get used to printing in color. Proper now, color is good to have, however we need to make it must-have.”
