3D print tip: A sleek 3D product without strings

When your 3D printer’s head needs to reposition from one point in your model to another, the filament might ooze. The result is stringing: small strings of material appear between the printed parts. Stringing especially occurs with models that have big open spaces, but there are ways to avoid it. The right material Whether stringing occurs, varies per material. For instance, ABS hardly causes strings but PET-G does. The material composition also has an effects, so the extend of stringing may differ per supplier. Retraction setting It’s possible to activate the retraction setting in the slicer software. This functionality makes the filament retract into the [...]

3D print tip: Creating a solid top layer

A 3D print usually consists of a solid exterior, filled with a grid. This saves time and material, with the same model as a result. Of course you want the outside to be smooth and solid, but that can be a challenge for the top layer. How do you ensure a strong and solid cover on your product? Prevent sagging The solid top layer is printed on top of the mentioned grid filling the print. This means that the top layer has to span the holes in the infill. Logically, the material sometimes sags through those holes. To make sure that the material reaches the [...]

3D printing becomes more accessible

Do you think 3D printing is a (too) big investment for your company? That could well be a misunderstanding. 3D printing becomes more and more accessible, in terms of acquisition costs and the required know-how to operate the printer yourself. Technologies keep on developing and of course the 3D printer is not an exception. The 3D printer too, is developing rapidly. There are several affordable, good quality plug & play 3D printers on the market, accessible for a wide audience. Over 25 years ago we didn’t even know what we could do with a 2D printer, and now we’re already in full development of 3D [...]

3D print tip: Why don’t my printing layers merge properly?

When not all layers of your 3D print are printed correctly, this is probably due to under extrusion. Under extrusion is a complex problem that can cause missing layers or layers that are not completely printed, leading to holes in the model. Unfortunately, we cannot point out one single culprit. Under extrusion can have various causes, which makes it hard to determine the actual problem. It mostly has to do with using the right extrusion width. Unfeasible extrusion width When we’re talking about extrusion width, we mean the width of the printing layer that the printer extrudes. How wide or narrow this layer can be, [...]

3D print tip: Creating a strong infill

dddrop 3D printtips: Creating a strong infill. The infill is an important factor in your product’s strength. Therefore, it’s important to prevent the infill from being too thin or stringy with the tips underneath. Various patterns: There are several infill patterns to choose from and they each lead to different tenacities. Examples of robust infill types are grid-shaped, triangular of solid honeycomb. Less strong are the rectilinear and the fast honeycomb infill. These less robust infills could however still be preferable, as these types can be printed faster and are robust enough for most products. Lower printing speed: The infill is usually printed slower than [...]

dddrop case study: High-precision parts with poly-carbonate

FROM DESIGN TO MANUFACTURING “Ejair offers a broad range of services, from technical design to the production of small series. We also produce scale models and prototypes. These are very useful, because you directly hold a physical product. For the production of prototypes and small series, Erik-Jan uses the dddrop 3D printer. His customers are mainly machine manufacturers: “A lot of machine parts are not exposed to extreme stresses, temperatures or pressure. Because it concerns one-off or small series production, it’s very interesting to print those parts in 3D”. “I already possessed a hobby printer, but I needed a more advanced one for the professional [...]

dddrop: printing your new house in 3D!

dddrop: printing your new house in 3D! Building your own house is an exciting project: What will it look like? Will it turn out the way you imagined? Sander Teunissen is the middle of such a construction project and dealt with the same questions until dddrop printed a 3D scale model of his house. The design When Sander and his wife bought the lot, they had the wish to design the house themselves, together with the architect. This way, they had the freedom to determine the layout and the angle of the light. Besides that, they decided to add solar panels and a heat pump. [...]

Nine landmarks 3D printed: De Achterhoek in 3D, a big success!

Exhibition: Achterhoek in 3D! Almost a year ago, an enthusiastic group of volunteers started an ambitious project: printing the Achterhoek in 3D. After a public voting phase, nine landmarks were chosen for production. The 3D print group used SOLIDWORKS to draw the buildings, after which they were printed with a dddrop 3D printer. Meanwhile, the project is finished and the prints of the buildings are shown in the Stadsmuseum in Doetinchem.           The process “We underestimated the drawing work” project employee Eefje Ernst says. “It was quite a lot of work, because the drawings need to be solid to print them [...]

Carbon fiber parts with dddrop 3D printers

3D Printing strong Carbon-fiber parts with dddrop 3D printers At the dddrop 3D printer laboratory the range of printing materials is expanding continuously. The PETG+Carbon material gives our users new possibilities printing high strength parts for applications that demand more than just plastics. The Carbon fibers are really improving the, already quite tough, PETG material specs to new heights. The material is not only strong but also can endure rough (outside weather) conditions. For example: It can be used to print custom clutch levers for top-level motorsports. Just imagine what you can make, using a dddrop Leader PRO and PETG + Carbon material!

Printing metal parts with dddrop 3D printers

Printing metal parts with dddrop The dddrop Leader PRO allows you to print full Stainless Steel parts at very competitive prices. dddrop developed parts, like special nozzles, to durable print the metal parts. Parts are 3D printed with a special metal filament: BASF Ultrafuse 316LX. After the 3D printing stage, the de-binding and sintering process is almost equal to the MIM (Metal Injection Moulding) pocess. The end result is a true and high quality Stainless Steel 316L part.
