To improve the bed adhesion and reduce warping of the first layer, several measures are available. For example, using a brim or raft that...

In a previous post the importance of controlling layer temperature is explained. In the latest prints poor results due to insufficient co...

The layer height is an important design parameter that impacts the printing time, cost, visual appearance and physical properties of a pr...

Since PP is known for its stubbornness to attach to other materials than itself, we were expecting some struggles with build plate adhesi...

When 3D printing thermoplastic materials the controlling of layer temperature is of great importance to create quality prints. By establi...

Here are the results of the first tests with new recycled PP material from Eco-Oh! We are glad to have found we made the right decision b...

Here are the test result of the overhang testing. With a layer height of 4 mm and overhang steps of 2 mm we managed to get good results w...

The Dutch national media service NOS published an article on the plastic recycling problem. Especially this infographic provides a good o...

By adding simple isolation around the nozzle we managed to increase the nozzle temperature from 60 up to 170 degree. Definitely one of th...

After many months of developing and testing to master the PE/PP material from household waste, our gathered data indicate that we will no...

Since the extruders end had an unusual external thread size for attaching nozzles, we decided to remove the end and replace it with a mor...

Earlier we announced a large upgrade of the extruder. One major challenge was to increase the amount of heating zones from 2 to 4. Splitt...

We found this interesting research on the relation of extruder screw geometries, melt viscosity and thermal efficiency. Highlights: • Rad...

Next lesson learned. An elongated nozzle is better for print quality. We are doing research into this area and have found a lot of intere...

Taking her apart. We have it on good authority that there are several things that need doing. Prio's are extra temperature sensors and ex...

Many types of plastics intent to absorb moisture from the air. Even the types of plastics that are consider non-hygroscopic attract water...

Since the extruder is an oldy, it was about time to give it a good clean. For maintenance of the barrel we used cleaning purge. Purging t...

Since the optimal layer height was found at 6.5 mm with a 5 mm nozzle, the layer bonding and printing height are up for the test. Startin...

The optimal layer height will differ based on the output of a used nozzle. As starting point 80% of the nozzle size is valid in desktop 3...

With the installment of couplers and nozzles the quality of the output greatly improved. Since recycled plastics from household waste are...
