Cum să proiectezi modele de imprimare 3D

Before you begin to printing your models, there are several important things to consider. Cutting and gluing are two common ways of assembling your models. Snap-fit and press-fit connections require no gluing after printing, and are often preferred for large props, exhibits, or prototypes. Regardless of your intended use, it’s essential to know how to design 3d print models for both types of printing.

If you’re planning to use mouse ears to design your 3D print model, it’s important to keep some things in mind. These little discs should be added to the corners of the base layer to prevent the model from curling at certain spots. Sharp corners are especially vulnerable to curling with PLA and ABS prints. By extending these mouse ears, you can prevent these issues and ensure that the entire model stays flat during printing.

Evitarea suprafețelor mari și plane

The build volume of a 3D printer is an important factor to consider when designing a 3D print model. A wide model requires a very large vertical build volume, which may mean that you’ll need to print it sideways. In such cases, avoiding large flat surfaces is a good idea. To avoid using support structures or adhesive aids, cut the model into two sections and attach them during post-processing.

Dacă modelul dumneavoastră are o suprafață plană mare, luați în considerare adăugarea de colțuri rotunjite sau reducerea dimensiunii elementului. Suprafețele plane mari sunt predispuse la deformare la imprimarea 3D, ceea ce poate duce la muchii și forme neuniforme. Deformarea poate fi redusă la minimum prin ajustarea temperaturii de imprimare, asigurarea unei aderențe netede la suprafață și utilizarea unor discuri auxiliare, dacă este necesar. Utilizarea colțurilor rotunjite și a suprafețelor plane sunt două sfaturi pentru evitarea deformării și a altor probleme potențiale la proiectarea imprimărilor 3D.

Utilizarea suporturilor

Utilizarea suporturilor este o parte esențială a proiectării unui model imprimat 3D. Deși un suport este necesar pentru a menține un model la locul său, îl puteți proiecta și pentru a fi detașabil. Suporturile sunt de trei tipuri: tip zăbrele, tip arbore și dizolvabile. Fiecare tip are proprietăți diferite. Suporturile ar trebui proiectate pentru a utiliza cea mai mică cantitate de material și suprafață de suport posibilă. O structură cu zăbrele reduce volumul suportului și economisește material, permițându-vă să proiectați piesele separat.

In general, supports are used for models that have steep overhangs or areas where they may not be supported. For example, the center of an arch might need a support material. Without it, the arch’s top layers would sag or droop. In such a case, it would be better to design the arch with supports rather than a simple bridge. However, if you do not plan to use supports, you may be tempted to skip them altogether.

If you’re planning to print a design yourself, you can make it look as professional as possible by taking a photo of the final product. It’s important to remember that your computer screen’s settings can make a big difference. Even if an image looks great on your screen, it will look completely different when printed. Therefore, you’ll need to match your computer screen’s settings with a known standard.

Curățarea unei printări 3D

Cleansing up a 3D print model doesn’t have to be a chore. With a few simple cleaning techniques, you can achieve the look you desire. In addition to sandpaper, you can also use a needle file.

Before cleaning up a 3D printed model, make sure you remove any excess support materials or blemishes. The support material is printed with the same material as the model, so it can easily be removed with your fingers or needle-nose pliers. The support material can also be removed with a little elbow grease using a putty knife. There are plenty of common tools you can use to clean a 3D print model, including a knife or toothbrush. Also, if you’re cleaning a print that has support materials, you can soak it in hot water with detergent. This will dissolve the support material.
