3D print tip: How to maintain your 3D-printer?

Does my 3D printer need maintenance? The first printing hours have passed and by now, your 3D printer has become indispensable for your development and production process. Before you leave for home at night, you quickly want to start the printer, so your prototype will be waiting for you in the morning. Nothing more frustrating [...]

3D print tip: How to perfectly print a thin-walled product

How to perfectly print a thin-walled product? With FDM printing, a model is constructed by printing layers of filament (plastic). This filament is heated until it melts and is then guided through the nozzle of the printer. The width of the layer that is printed onto the print bed is partly determined by the size [...]

3D print tip: How do I make sure that my print does not warp?

Especially with ABS but also with less common materials like nylon, the materials sometimes wants to deform during printing. This warping leads to unsuccessful products and sometimes even to a hard hit: the printhead clashes up against the pulled up material. Naturally you want to avoid that! Why does a product warp? A print can [...]

3D print tip: What is delamination and how do you prevent it?

We are talking about delamination in 3D printing when there is a shrinkage higher in the product, during printing. When and how fast a product shrinks depends heavily on the type of material you use while printing. PLA and PET-G are not sensitive to this, but when you use more complex, shrink-sensitive materials such as [...]

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 [...]

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 [...]

3D print tip: Creating a strong infill

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, [...]

3D print tip: How do I keep my nozzle running smooth?

How do I keep my nozzle running smooth? Sometimes the filament does neatly get transported into your printer, but it doesn’t flow from your nozzle. It piles up in the print head. Why does this happen? And of course: how can you prevent this? Piling up in the nozzle When the nozzle is obstructed, [...]

3D print tip: How to increase your 3D printing speed

How to increase your 3D printing speed Fast prototyping is possible with a 3D printer. However, sometimes a higher 3D printing speed is preferred. Our helpdesk often receive the question whether it is possible to increase the 3D printing speed. This is possible, but it may affect the quality of the 3D print. In [...]

3D print tip: How-To? Control the right Nozzle – bed distance

With many different printing materials it can be challenging to find the right distance for the print-nozzle towards the glass bed-surface. We are now implementing a standard setting for most different materials PLA, ABS en PET-G. Where ABS needs a pretty small distance, PET-G needs more space. The perfect distance is also somewhat depending on [...]
