Tips, tutorials, model spotlights, and 3D printing deep dives from the OreKo team. Whether you are just starting out or fine-tuning your setup, there is something here for you.
Deep dives into individual OreKo models. Print settings, assembly tips, filament recommendations, and what makes each design tick.
Step-by-step tutorials on slicing, print settings, filament selection, bed adhesion, post-processing, and more. Written for real printers, not perfect conditions.
Card game setups, cosplay builds, dollhouse projects, and community prints. We cover the culture around the hobby, not just the hardware.
When you print a multi-color model using the AMS system on a Bambu Lab printer, a separate small tower appears beside your model on the print plate. This is the purge tower. It exists to flush the previous color out of the nozzle before the new color starts printing on your model. Without it, every…
Removing a finished print from the bed should be simple: the part releases cleanly and comes off without damage. When it doesn’t, either the print is stuck too hard or too loose, and both have straightforward fixes. Here is the right technique for every situation. The Right Way: Let It Cool First The single most…
Gluing 3D printed parts together is one of the most common finishing tasks in FDM printing. Multi-part prints, repairs, and assemblies all need reliable adhesion between PLA, PETG, or other printed surfaces. The right adhesive depends on the joint size, the load it needs to carry, and how quickly you need it cured. Here is…
Top and bottom layers are the solid surface skins on the top and bottom of a 3D print. They’re separate from the walls and infill, and the number you set directly affects how solid and clean those surfaces look. Too few and you get gaps. Too many and you’re wasting material on overkill surface thickness.…
Why PLA Slicer Settings Matter More Than the Printer The same PLA filament on the same printer will produce dramatically different results depending on slicer settings. Get temperature, speed, retraction, and cooling right and PLA prints clean, strong parts every time. Get them wrong and you get stringing, warping, weak layer adhesion, or surface quality…
What Warping Is and Why It Happens Warping is when the corners or edges of a 3D print lift off the build plate during printing. The base of the print peels away from the bed, the part deforms, and in severe cases the print detaches entirely mid-job. The physics behind it are straightforward. Plastic expands…
What Stringing Is and Why It Happens Stringing is the thin threads of filament left between parts of a print when the nozzle travels across an open gap. The nozzle moves from one section to another, and instead of leaving nothing behind, it drags a fine strand of melted plastic across the gap. On a…
What Under Extrusion Is and How to Spot It Under extrusion happens when your printer deposits less filament than the slicer expects. The nozzle is moving and the filament is feeding, but not enough plastic is coming out to fill the path correctly. You will see it as gaps between infill lines, weak or porous…
Printing threads and precise holes in FDM requires accounting for how FDM slightly under-sizes holes and the specific design constraints that make threads printable versus fragile. Get the tolerances right and your printed threads work on the first try. Get them wrong and you have a part that either won’t thread or strips after two…
The Nozzle Nobody Thinks About (Until Something Goes Wrong) Most 3D printers ship with a 0.4mm brass nozzle, and most people print every single job with that exact nozzle for the entire life of the printer. For the majority of use cases, that is the right call. But knowing why and knowing the specific situations…
Variable layer height lets your slicer automatically use fine layers where the model has curved or detailed surfaces and coarser layers on flat sections where layer lines aren’t visible anyway. The result is a print that looks like it was printed at a fine layer height throughout, but takes significantly less time because it uses…
A few months into 3D printing, most makers have a Downloads folder full of STL files with names like “thing-2345678.stl” that they can’t find when they want them. An organised file library lets you find any model in 30 seconds, know which settings you used last time, and avoid reprinting something you’ve already printed and…
