Arch Graphic is a 3D printing service company based in Sharjah, United Arab Emirates. Founded in 2010, the company specializes in 3D printing architectural modelsand models for interior design, but has evolved over the last decade to offer its clients a full range of prototype and small volume production services. The foundation of the company’s service offering is based on high quality models provided at competitive prices.

To enable this core company principle of high quality with accessible prices, Arch Graphichas partnered with FELIXprinters as its key 3D printing technology supplier since 2015, when the company invested in the FELIX Pro 1 system. The quality and reliability of the machine quickly became apparent and the company has continued to build its 3D printer capacity based on FELIX Pro systems.

3DP & Architecture

Architects have long used physical 3D scale models of their building designs to visually convey their vision. However, traditional scale models were often painstakingly built by hand, using fragile materials, such as paper and cardboard, that were barely fit for purpose, particularly in humid weather conditions such as those in the UAE region. It is not surprising, then, that the advent of 3D printing found a natural home within the architectural sector or that the demand for Arch Graphic’s services in the UAE was high. Architectural models and 3D printing are a natural fit.

Indeed, this is an application area that evolved quickly, particularly as the technology matured, for producing stronger and more accurate demonstration models of an architect’s vision. In this regard, 3D printing offers a relatively fast, easy and economically viable method of producing detailed models directly from 3D CAD, BIM or other digital data that architects use. Many successful architectural firms, now commonly use 3D printing as a critical part of their workflow for increased innovation and improved communication. This latter point is a particularly critical factor for Arch Graphic as architectural design models help communicate ideas to clients, planners and stakeholders more widely.

Since its inception, the goal of Arch Graphic has been to grow its Architectural Practice by providing its clients with stunning 3D printed visual models, custom designed components, with the ability to offer fast design iterations as required. To this end, the company has successfully built its 3D Print Hub in UAE supplying clients with architectural models that not only reduce the overall process time compared with handmade models, but also offer a precise finish and superior quality, with options for safe lighting systems that can avoid heating.

Arch Graphic also offers a comprehensive model making service for interior designers, making it a one-stop-service. Here too, the benefits of 3D printing can be maximized in reducing the time and expense of producing 3D models that often require highly delicate details.

Arch Graphic has continued to build its brand through the talent and vision of its leadership, including distinguished architects Alaa Younis and Rula Kaddoura, who have worked at the state level producing superior performance 3D printed architectural scaled models for a range of prestigious projects.

Arch Graphic & FELIXprinters

In 2015 Arch Graphic was searching for a distinctive 3D printer that would meet its demanding requirements as the company continued to grow in size and reputation across the UAE. Its introduction to FELIXprinters at this time proved to be the beginning of an ongoing partnership that has been mutually beneficial. According to Alaa Younis: “The investment into the first, wonderful Felix Pro 1 was a revelation. It was exactly what we needed. Working with Wilgo [Feliksdal], who worked closely with us through installation and growth, was also a key reason for us selecting FELIXprinters as a technology partner. The introduction of the FELIX Pro systems have certainly contributed to Arch Graphic becoming distinguished in the creation of architectural models produced by 3D printing in the United Arab Emirates and the GCC as well. We have completed many 3D printed projects at the local and regional level using our Pro Series 3D printers from FELIX.”

One of the earlier 3D printing projects that Arch Graphic undertook on its FELIX Pro 3D printers at this level was the first scaled model of a new mosque that was to be built in the UAE, which was designed by the Arch Graphic team. The FELIX printers were essential to this model, in terms of the precise details involved and the quality output. The project also involved some manual assembly of the 3D printed parts — a total of 755 individual  pieces were printed and assembled to produce the completed model with overall dimensions of 85 x 85 X 75 cm.

Younis states that: “The accuracy and precision of the FELIX 3D printers ensured that we were able to assemble the parts of the model easily and without errors to get the end result painlessly. At first we were surprised, but quickly appreciated the capabilities of the system we were using, and the model was a huge success whereby we received many positive responses from government authorities and non-governmental companies in the UAE as a result. It’s also why we invested in more FELIX 3D printers.”

The individual pieces were produced in different colours of PLA material, to reflect the full intent of the original digital design that proposed a building that provides harmony with the surrounding area and is harmonious with that natural environment of the UAE. As such the building design, as illustrated perfectly by the physical model, is symmetrical in nature. This is all the more impressive, considering that Younis and his team printed all of the parts, utilizing just under 6 Kg of material, without the need for supports, thereby minimizing any post processing steps and wasted material. The project was completed in two weeks.

Working in Partnership

Over the last five years, FELIXprinters has become a critically important partner for Arch Graphic. Younis explains: “The FELIX team provide us with ongoing technical assistance — both directly concerning the hardware with rapid and exceptional support and also for application development to enable us to maximize the potential of the 3D printers. This was a kind of strong friendship and a strong partnership between Arch Graphic and Felix.”

He continued:“I believe our choice of FELIXprinters has been the main reason for our success with 3D printing scale architectural models and why we have been able to offer excellence to our many clients in the local market. The capabilities of the FELIX Pro systems and are partnership with the FELIX team keeps us at the forefront in our sector and region.”

Expansion & Growth

Having quickly realized the benefits that the Pro 1 offered the business in terms of the high quality, reliable and cost-effective prints, Arch Graphic rapidly added another FELIX Pro system to the company’s portfolio. Continually evolving and adding new capabilities, today Arch Graphic is distinct through its ‘unconventional’ stereoscopic service, which combines 3D printing highly detailed models, with hand finishing skills to create miniature buildings. At the other end of the scale Arch Graphic is able to produce large scale models in new ways, combining many parts into one and incorporating highly complex internal structures.

Today, the 3D printing services offered by Arch Graphic and powered by FELIX Pro 3D printing systems, is, according to Younis: “the main engine of our work.” The company’s profile and number of projects is expanding week on week, to keep pace with the urban development in the United Arab Emirates. This is also supported by the recognition of the importance of the technical field of 3D printing by the Government of Dubai.

Arch Graphic is determined to keep building on its reputation and develop new projects in the short and long term across the UAE, and fundamental to this is the continued strong partnership with FELIXprinters.

FELIXprinters is established as one of Europe’s leading manufacturers of highly accurate, reliable, easy-to-use, and price sensitive industrial AM machines. As many industrial sectors have shifted their manufacturing workflow to incorporate AM, FELIXprinters has positioned itself and its portfolio to serve the changing needs of industry. This is achieved through careful attention to detail, listening to what customers say is important to them, and developing products and features to meet their needs. The company’s Pro 3 & Tec 4 series of AM platforms — and the newly introduced Pro L and XL models (with larger build envelopes) — have cemented FELIXprinters’ position in the industrial use of AM, and has opened up an array of options for manufacturers previously unavailable.

Customer & Partner

A customer of FELIXprinters is S-CAN 3D Ltd, based in Attleborough, United Kingdom offering a 3D scanning, CMM inspection, and precision manufacturing bureau service for international customers. The company specialises in 3D scanning for reverse engineering, but also has its own product range which include RetroSport (billet aluminium performance parts for classic Minis) and S-FIX (accessories for precision measuring equipment).

S-CAN 3D was founded in 2012, and over the last number of years has invested in a large arsenal of equipment to be able to take a customer’s component, reverse engineer it, and then re-manufacture it. The company uses FELIXprinters AM platforms for prototyping, creating casting moulds and masters, and manufacturing jigs.

James Senior, MD at S-CAN 3D says, “We have found FELIXprinters AM platforms to be very easy to use. You can be up and running within a few minutes of getting them out of the box. We run all of our printers through Simplify3D software so you load the profile, pick a material and you are ready to go. In-house we now have the first machine we bought from FELIX back in 2015 (the Pro 1), and a Tec 4.1, a Pro 3 and the new Pro XL. Our first Pro printer has paid for itself 10 times over.”

FELIXprinters has a range of machines that are aimed at industrial prototyping and production applications, key among these being the Pro 3 and Tec 4 machines and the more recently introduced Pro L and XL platforms.

The Pro 3 & Tec 4 machines are supplied with automated and intelligent features to maximize productivity and efficiency. The importance placed on intelligent 3D printing is really at the heart of these machines, with functionality that removes many of the time-consuming hurdles that characterize many 3D printers. To this end, Pro 3 & Tec 4 machines are characterised by automated motorized calibration; an innovative quick-swap print-head solution; extremely fast rotation of print-heads in the dual head configuration (less than 10 seconds); and a dedicated flexplate, supplied as standard to easily and quickly remove printed parts.  Moreover, the Pro AM systems also offer extremely quick heat-up and cool-down of the print heads, meaning that the dual head print times are reduced by a factor of 2.

Scaling Up

The more recently introduced Pro L and Pro XL machines cater for FELIX customers that want bigger build envelopes but without compromising on quality. Delivering on this was not just a case of scaling up the architecture of the Pro 3D printers. With the Pro L and XL, FELIX has used all of its experience in precision engineering to develop what it believes is an offering to the market that demonstrates te company’s commitment to robust and reliable 3D printers. These bigger machines can fit seamlessly into any workshop, lab or factory environment because they can fit through a standard doorway, to make the logistics of installation quick and simple too. The Pro L and XL have build envelopes up to 144 liters.

Senior discusses S-CAN 3D’s use of the FELIX 3D printers. “The Pro printers have been our workhorses for the last few years. The original Pro 1 has over 400 days of continuous build time logged on it. 
We were interested in the Pro XL from when it was announced, and we certainly haven’t been disappointed with it since it has been installed. It’s averaged over 20 hours per day run time since we have got it, making everything from show display pieces to casting patterns. We’ve done week long and maximum build area builds so I can only really talk positively about our experience with it so far.”

Senior continues, “Internally, S-CAN 3D use FELIX 3D printers for prototyping designs. We might do five or more different concept designs of a particular part or component, as it’s much easier to visualise a part when it’s in your hand. 
We are putting a lot of work through the newly purchased XL printer and it’s opening up things which we wouldn’t have been able to do before (at least to the same quality and size), so things are very encouraging.
We have found FELIX machines to be very repeatable which is our most fundamental requirement for any application, and we also haven’t noticed any accuracy degradation over time.”

It is specifically because of the gap between supply of lower cost, reliable and accurate 3D printers and the demand from companies such as S-CAN for affordable industrial platforms that FELIXprinters has developed it Pro series and L & XL machines. Throughout its history, FELIXprinters has achieved a strong reputation for developing and delivering robust, reliable and accurate machines, servicing a growing client base with solutions that are far in excess of their requirements in terms of accuracy but at a price that is comparable with inferior alternatives.

One of FELIXprinters’ customers is Recair B.V., which produces air-to-air heat exchangers from thin thermoformed sheets. These heat exchangers are used in residential ventilation units and provide heat recovery of up to 90%.Key to the success of the company is the optimization of these heat exchangers through the adaptation of the thermoformed shape.

Recair uses additive manufacturing / 3D printing as a rapid prototyping technology, with some of the company’s developments (such as measurement setups) being subject to incremental upgrades during development. The company uses 3D printing to get visibility of a prototype quickly and inexpensively, and to allow the fixing of design issues before costly tooling and manufacturing processes are initiated.

Initially, Recair outsourced all of its 3D printing requirements to subcontract agencies. The company did consider purchasing an industrial printer for in-house use, but postponed this decision due to the significant (€10-20,000) capital investment required to meet its quality needs. At this time, the volume of parts did not justify the expenditure.  However, the demand for higher volumes of 3D printed parts increased and the company required multiple prints such that the in-house ownership of a 3D printer became economically favourable. At this point Recair approached FELIXprinters.

Stein Hendriks, R&D Engineer at Recair commented: ”There are a number of alternative additive manufacturing options available to manufacturers, but not all machines are the same. Supplier selection is key to success, as the AM platform that you choose has to perform to the levels required for your specific applications. Recair ultimately chose FELIXprinters’ Pro 3 industrial 3D printing platform, which we use to fully optimise our designs without having to expend significant time and money. With a large amount of designs in development, the cost of prototyping using milling, injection moulding or thermoforming is extremely costly and time consuming.”

“We like to be able to get our hands on numerous prototypes early in the design-to-manufacturing cycle as this gives us a much better idea of the optimal nature of a design for end-use applications. We pick up design errors and flaws in the prototype, which can be overlooked in a 3D CAD render, and which are extremely expensive to correct once tooling has been cut and manufacturing initiated. We chose FELIXprinters as our preferred supplier for a number or reasons, including the dual extrusion functionality inherent in the platform, and the ability to switch to a stainless steel nozzle for carbon reinforced printing. The larger size of the build plate and layer resolution was also a key factor in choosing FELIXprinters’ 3D printing solutions, as was its ease-of-use, and low failure rates,” Hendriks concludes.

Throughout its history, FELIXprinters has achieved a strong reputation for developing and delivering robust, reliable and accurate machines, servicing a growing client base with solutions that are far in excess of their requirements in terms of accuracy at a price that is comparable with inferior alternatives. With the drive towards the adoption of AM for industry and manufacturing applications, FELIXprinters has logically leveraged this reputation and made an intelligent and concerted move to provide industrial AM solutions, at a price that makes them accessible to many industrial customers hitherto unserviced, and with an emphasis on true workflow integration and ease-of-use.

The FELIXprinters industrial AM machines vary in cost from approximately €3000 to €15,000 depending on the build envelope required, and therefore present robust manufacturing solutions at an affordable price point. The full range of the company’s industrial AM machines are backed up by an array of ancillary products and services, a proactive post-sale “partnership” which is expected when companies adopt AM for industrial applications and an excellent warranty that belies the quality and reliability of the hardware. Indeed, FELIXprinters take the concept of partnership further than any other AM technology suppliers, and offer a service which allows for the manufacture of bespoke tailor-made AM platforms for specific customer applications as well as off-the-shelf solutions.
