[CASE] How we did the layout of the Novo Nordisk building



This is the story of how we mocked up the building of the pharmaceutical company Novo Nordisk.

The popularity of 3D printing in architecture is growing. Architectural models are popular not only among developers and architects, many companies do not mind decorating the interior with 3D models of their buildings. This is one such order.



Order


The request from the client came with ready-made renderings of buildings, structures and infrastructure, with a general plan of the territory and several photographs of the real object.



It was not possible to get the 3D models by which the renders were created, but this is not important - when creating the layout it is much more convenient to work on your own models, creating them from scratch.

How was it done before


Before the advent of 3D printing and software-controlled machines, models were created manually from paper and polystyrene, which had its own characteristic drawbacks, such as low accuracy and production time.

How did we do


Project


Since we only had a couple of photographs, renderings and a BTI plan for a small part of the main building, the scale was selected for a long time, tried on. They did several renderings of the bases. Compared with the original images. One of the requirements of the customer was to place the layout on an area of ​​not more than 1 sq.m. Everything was done. The total area of ​​the sub-bed was 0.97 sq.m.



At the stage of evaluating the layout, it became clear that the main building on the territory is quite long. In this regard, it was decided: to make a model based on the internal "skeleton" of this building. Further - facing, then - small details. All objects have clear shapes and angles. This observation allowed us to choose the appropriate material - acrylic. It is flexible enough, but not too, just right. When milling or cutting on a laser engraver, clear contours and edges remain on the parts from the acrylic sheet.



The frame of the main building consisted of 4 mm thick acrylic.



This optimum thickness, taking into account the dimensions of the structure itself, is convenient for work and gives sufficient rigidity.



The model was modeled as a prefabricated designer, taking into account the tolerances (0.1 mm) and the cut thickness of the laser machine (0.13 mm).

After that, a model of the territory was worked out, paths, foundations of buildings, parking lots, curbs were placed on it. All elements were engraved 1 mm deep, on plywood 9 mm thick, and cut.



We designed the remaining buildings on the territory. Half was also produced by assembling sheet materials, the other half was 3D-printed using SLA and FDM technologies.



Creature


While the prototype maker worked on the finished parts - assembled, primed, polished and polished, the engineers prepared the cladding of the main building. The choice fell on acrylic at 3 mm. Relief engraving on 0.5 mm. Windows and doors are cut through.



Next is the gluing assembly. All elements converged as expected. The tolerances indicated above played a role. The layout assembled as a designer.



An OSB plate with a thickness of 15 mm was used for the submaster.



Puttying, then priming, painting in black and matte varnish in four layers. This is necessary so that the acrylic cap does not leave marks or scratches on the upper surface of the base, in order to preserve the appearance.



Processing and painting


Next - all the most juicy and interesting. This is the treatment of buildings and painting.
After assembly, all elements were covered with several layers of soil. Thus, we preserved the texture and relief on the buildings, but at the same time, the soil revealed various surface defects.



They were eliminated in the old fashion - manual machining, sandpaper mainly.



The inside of the frame was painted black and varnished so that the interior lighting was not visible through the walls.



It was possible to use black acrylic and not bother, but transparent was already in stock and we saved time, which is important - the order dates were quite tight.



To make the roof textured, we used acrylic polishing dust. Sprayed it when painting. This created a uniform coating with dispersion.





Backlight


An important part of the project was the LED backlight. Inside the building, a foundation was laid in the form of a processed beam. A tape was attached to it. The wires were routed through the base. The power supply is attached to the base from the bottom. This is a good strategy, since the OSB is not flammable and does not burn. In the event of a malfunction or short circuit, the backlight will simply fail.



The PSU is removed in a box printed from ABS plastic on an FDM printer. A toggle switch for turning on and off the backlight on the power wire is provided.





Details


Initially, the logo was designed according to the image from the customer. Made on a Form 2 printer using SLA technology and hand-painted with a brush.



The result did not suit us, the logo was redrawn in high resolution and sent to UV printing.





Cars are printed by SLA technology on the same printer and hand-painted.



It was possible to get somewhere ready-made, but it would have been longer, and the originality in the project would have decreased.







The pipes are designed and also printed. Processed, sanded and painted.



Flagpoles are made of steel to maintain rigidity with a length of 25 cm and a diameter of 1.5 mm. They laid a flock - an imitation of grass.



Cap


We made a cap of acrylic with a thickness of 4 mm. The cap is one-piece and covers the entire layout. Installed with a small gap. Better a bit more than not getting into tolerances.



Difficulties and their solution


Having almost finished the layout, we ran into a problem that greatly affected the entire project. The fact is that the geometry and location of the entrance group on the main building differed on each render from the customer, and there were no concrete instructions about which design to consider the main one, so I had to improvise, which was the wrong decision - when the customer agreed on the results of work for the first time He also pointed out that the entrance group does not correspond to reality, several more minor inaccuracies were also revealed.



With the personal participation of the customer, an act was drawn up indicating all the problematic elements, the specified corrections and deadlines for the delivery of the final version are clearly spelled out.



conclusions




At the stage of coordination of large-scale projects, we ask customers a lot of questions and discuss a lot of subtleties, but this situation once again taught us that there are not many questions, and the amount of information received directly affects the result of the work.
