3D Printing Terms You Need to Know
Despite their enthusiasm, many newcomers to 3D printing soon lose their bearings when confronted with the industry's jargon. Slicer settings and printer instructions use confusing terms such as "infill," "retraction," and "G-code," making the process more difficult to understand. Errors, failed printing, and general aggravation can result from this muddle. A few key terms for 3D printing can help clarify things, which is great news. Gaining a grasp of these ideas can empower you to use your printer with confidence, expedite problem-solving, and improve print quality.
1. Filament
Most FDM 3D printers use filament, a type of plastic. It is fed into the printer on long spools and melted layer by layer within the hot end to create an item. The temperature requirements, flexibility, and strength of filament materials, including PLA, ABS, PETG, and TPU, vary.
2. Extruder
It is the job of the extruder to feed filament into the hot end. Through the use of gears, it controls the amount of material that enters the nozzle and grasps the filament. Printing with constant extrusion and exact dimensions is possible with a calibrated extruder.
3. Hot End
Just before the filament is about to leave the nozzle, it is heated in an assembly known as the hot end. A thermistor, heater block, heat break, and nozzle are some of its parts. In order for the hot end to work with a certain filament, it needs to get hot enough.
4. Nozzle
Extruding molten filament requires a tiny metal tip, or nozzle. You may get nozzles in diameters ranging from 0.2 mm to 0.6 mm. A larger nozzle allows for quicker printing, whereas a smaller one produces more detailed prints.
5. Print Bed
You can create a 3D model on a flat surface known as the print bed. It is on this surface that the initial print layer adheres. A heated bed is a common printing accessory that helps with adhesion and minimizes issues like warping.
6. Bed Leveling
Make sure the print bed is sitting flat in relation to the nozzle by doing bed levelling. Making sure the bed is level before printing the first layer is essential. Prints may come loose or fail at an early stage due to improper levelling.
7. STL File
Models created with 3D printing often come in an STL file format. It uses a triangle mesh to depict the object's outside geometry. This is the default format for most 3D models found on the internet repositories.
8. Slicer
A slicer is software that takes a 3D model and converts it into printable instructions. It creates a G-code file after layering the model. There are many that are available, but we recommend using SelfCAD’s online slicer.
9. G-Code
One of the languages used by 3D printers is G-code. Among its contents are instructions for the printer's location, speed, and temperature settings. Just before printing, the slicer will automatically create this file.
10. Layer Height
The height of a printed layer is the measurement of its thickness. Printing using smaller layers takes more time, but the surface is smoother and more detailed. Printing quicker with larger layer heights comes at the expense of finer details.
11. Infill
What makes a 3D printed object "infill" is its internal structure. It reduces material consumption without sacrificing strength. You can change the infill density based on how much strength or structural support the object needs.
12. Supports
Printing out temporary supports allows you to keep the model's outward-extending elements in place. During printing, they keep parts that hang over from collapsing. These supports are removed once the print is finished.
13. Build Volume
The build volume of a 3D printer is the largest object it is capable of producing. The three axes of measurement are X, Y, and Z. Users are able to print larger models or more parts at once with larger build volumes.
14. Warping
The borders of a print lifting off the bed when printing cause warping. The material's uneven cooling is usually to blame for this. You can lessen the severity of this problem by using heated beds, an enclosure, and good bed adhesion.
15. Retraction
As the nozzle travels between printing regions, it retracts, drawing the filament slightly backward. This stops the filament from escaping and creating fine threads between the printout's various sections.
16. Overhang
An overhang occurs when one layer of a model extends beyond another. Because there isn't much support for the filament underneath, large overhang angles could lead to printing issues.
17. Bridging
The printer creates a bridge when it lays filament across a space without a supporting structure underneath. A combination of cooling, accurate speed settings, and filament qualities determines the bridging performance.
18. First Layer
All 3D prints begin with the first layer. The success of the print job depends on how well the first layer adheres to the bed during printing. The first-layer settings are fine-tuned by several users.
19. Bed Adhesion
The concept of bed adhesion pertains to the degree to which the printed item clings to the build plate. The print won't shift or come loose from the substrate if the adhesive is strong enough.
20. Brim
Brims are thin layers of additional lines printed around the model's base. The increased contact area with the bed improves adhesion, whether the print is small or tall.
21. Raft
Just under the model, there's a thick grid structure called a raft. On challenging materials, it helps to build a stable basis and reduces the likelihood of warping.
22. Skirt
A skirt is a pre-printed line that encircles the model. It aids in priming the nozzle and stabilising filament flow without touching the item.
23. Direct Drive Extruder
A direct drive system has the print head mounted directly on the extruder motor. Improved management of flexible filaments is a result of this design.
24. Bowden Extruder
Bowden extruders separate the print head from the motor and use a tube to feed filament. This makes printing go more quickly by reducing the load on the moving components.
25. Print Speed
The rate at which the printer deposits filament is defined by the print speed. Printing at faster speeds saves time, but the quality could suffer.
26. Travel Speed
When not printing, the nozzle's travel speed is what matters. Cutting down on printing time and stringing is possible with faster travel rates.
27. Fan for Cooling
A cooling fan propels air onto newly printed layers. This increases the quality of fine details and speeds up the filament's solidification process.
28. Thermistor
Within the heated bed and hot end is a thermistor, which is a temperature sensor. In order to keep the printer from overheating, it monitors the temperature and relays that information.
29. Heated Bed
To improve the adhesion of the initial layer, a heated bed warms the work surface. For materials that contract when cooled, it works wonders.
30. Build Plate Surface
Whether it's glass, PEI sheets, or textured plates, the build plate surface is what sits atop the print bed. A variety of surfaces provides varying degrees of adherence.
31. Stringing
Stringing occurs when fine filaments of plastic protrude from the spaces between various print elements. In most cases, this happens because the retraction settings aren't perfect.
32. Layer Shifting
The printer experiences layer shifting when it becomes disoriented and prints successive layers at a small angle to the ones before them. Loose belts or other mechanical problems are common culprits in this situation.
33. Z-Axis
In a printer, the Z-axis dictates how the machine moves vertically. After finishing a layer, it elevates the print bed or head.
34. Stepper Motor
The printer's axes may move thanks to stepper motors. Their methodical progression enables the printer to precisely place the nozzle.
35. Firmware
The firmware is the computer code that runs on the motherboard of the printer. It coordinates motion, regulates temperature, and talks to the slicer.
36. Mesh Bed Leveling
In order to identify any uneven spots, mesh bed levelling measures multiple places throughout the bed. When printing, the printer makes adjustments to account for these variations.
37. Linear Advance
One firmware feature that helps with extrusion control is linear advance. It improves the precision of the lines and corners by adjusting the pressure within the nozzle.
38. Flow Rate
The amount of filament extruded while printing is controlled by the flow rate. The proper dimensions of printed components can be better guaranteed by adjusting the flow rate.
39. Print Resolution
The print resolution of a 3D printer is the degree of detail it is capable of producing. Variables including printer accuracy, nozzle size, and layer height all play a role.
40. Calibration
Calibration is the procedure of fine-tuning the printer's hardware and settings to produce precise prints. Calibration on a regular basis enhances print quality, dimensional accuracy, and dependability.
