3D printing has revolutionized manufacturing, offering versatile technologies tailored to different needs. Among the most popular are FDM (Fused Deposition Modeling), SLS (Selective Laser Sintering), and SLA (Stereolithography). Let’s explore how they compare:
1. FDM (Fused Deposition Modeling)
How it works: Melts and extrudes thermoplastic filaments layer by layer.
Best for: Affordable prototyping and low-volume production.
Materials: PLA, ABS, TPU, PETG, PEI, and more.
Key benefits: Cost-effective, easy to use, suitable for functional prototypes.
Drawback: Limited surface finish and detail resolution.
2. SLS (Selective Laser Sintering)
How it works: Uses a laser to sinter powdered polymers into solid layers.
Best for: Complex geometries and durable end-use parts.
Materials: Nylon and other thermoplastics in granular form.
Key benefits: No need for support structures, excellent mechanical properties.
Drawback: Higher cost and limited material options.
3. SLA (Stereolithography)
How it works: Cures liquid resin with a UV laser to create precise layers.
Best for: High-detail prototypes and smooth, aesthetic finishes.
Materials: Photopolymer resins.
Key benefits: Exceptional resolution and surface quality.
Drawback: Fragile parts and higher material costs.
Choosing the Right Technology:
Budget-friendly? Go for FDM.
Complex designs? Opt for SLS.
Aesthetic precision? Choose SLA.Each technology has its strengths, making it essential to match your project’s needs with the right process. With 3D printing, you can bring your ideas to life efficiently and effectively.

This also happened to me when I was given a task from my company, Rent a Car Bur Dubai, and I compiled for it. So what I can recommend is:
Ensure that the correct board, "AI Thinker ESP32-CAM," is selected in the Tools menu of your Arduino IDE.
If the board is not listed, you may need to install it through the Board Manager. Search for "ESP32" and install the latest version.
Ensure that necessary libraries like ESP32-CAM, WiFi, and HTTPClient are installed. You can install them through the Library Manager.
Carefully check your code for typos, missing semicolons, or incorrect syntax.
Verify that you're using the correct function names and parameters. -
@Vishnuraj2003 Are you able to fix it?

Hi @PumpedMedusa, The rage is depends on the Antenna and how much TX power you have.
To choose antenna, first you need figure out - where your nodes will be, take a look at the below image. The antenna act like a "torch" if you have more dbi that mean it's focus will be increase and it can reach more distance but the angle it have it less, like a laser.
also, obstacle such as buildings, tress and mountains will affect the signal and deplete it.
So, answer for you question - What is the best LoRa module to use for long distance network? - It's really depends on where you planning to put the nodes and how high you putting the gateway. Let me know know your thoughts.
