Everything you need to know about laser engraving Laser engraving is a term generally used to describe the use of laser beams to engrave images and text on objects. https://www.htpow.net/sculpfun https://www.htpow.net/sculpfun-s10-10w-laser-engraver-with-high-speed-air-assist-nozzle

It is now also used loosely for any marking of objects done with the user. As a result, laser engraving, laser marking and laser etching are often used interchangeably. However, these marking techniques are completely different. https://www.htpow.net/laser-engraving-machine https://www.htpow.net/sculpfun-s30-pro-max-20w-laser-engraver

This article details what a Sculpfun laser engraver is and how it differs from other techniques that can be done with the help of a laser. We will also give you some tips on how to choose a top-notch laser engraver for your company or business.

Let's start by looking at the proper description of laser engraving.

What is laser engraving? Laser engraving is a subtractive technique used to change the surface of an object with the help of a laser beam.

This technique is used to create images and designs that are visible to the human eye. Thus, the image is visible to the human eye regardless of its size.

In laser engraving, a hot beam from a laser vaporizes the contact area on the object. The beam will then create a cavity in the object to form the desired image or design.

Types of engraving machines and how they work Engraving is a very fast process due to the heat beam. Therefore, apart from the complexity of the design, you will get the desired result in a short time.

The depth of the engraved design depends on the number of times the beam passes over the object. The higher the frequency, the deeper the inscription.

There are three types of engraving machines. The first type is the Sculpfun S10 laser engraver, which is designed in such a way that the object remains stationary while the machine moves over it to create the design, or while the technician moves the object under the laser beam.

The second category Sculpfun S30 Pro Max laser engraving machine is a laser engraving machine designed specifically for cylindrical pieces.

The third category laserpecker 4 laser engraving machine is one in which the object and the machine remain stationary throughout the process while a set of mirrors called oscillators are used to direct the laser beam to the part of the object to be engraved.

Leather Laser Engraving Projects

Leather Laser Engraving Tips For You Sculpfun laser engraver can engrave on genuine leather and artificial leather. https://www.htpow.net/sculpfun-s10-10w-laser-engraver-with-high-speed-air-assist-nozzle You can engrave logos, patterns and any other designs on the leather.

However, you should avoid faux leather made from PVC as it produces hydrochloric acid gas which can damage the lens of your laser engraver . https://www.htpow.net/90w-sculpfun-s9-laser-engraver-cnc-laser-cutting-engraving-machine

To cut leather you need a laser with a minimum power of 10W, lasers lower than that are not recommended. For example Sculpfun S10 can cut leather, but sculptfun s9 cannot cut leather. https://www.htpow.net/sculpfun-s30-pro-max-20w-laser-engraver

With the Sculpfun S30 Pro Max with 20W laser, you can achieve faster speeds for cutting single ply leather sheets. https://www.htpow.net/sculpfun

Low power lasers have to run at low speeds to get deep enough to cut, eg: Sculpfun S9. https://www.htpow.net/laser-engraving-machine

Continuous laser exposure at one point in the leather can cause heat buildup and fire. https://www.htpow.net/

Engraving leather with a laser is much better than using some sharp tools.

When the laser beam burns the leather, the crevices and edges of the incision are filled with burn residue.

When the gaps are filled, fungal buildup in the leather is less likely and lasts longer.

Compared to other materials, leather can display your designs well in any color.

Even the laser engraving on the black leather is very pleasing and easy to spot.

The difference between laser engraving machine and CNC engraving machine

When it comes to the difference between alaser engraverand a CNC engraving machine, the most obvious difference is that theSculpfunlaser engraving machine uses laser melting, while the CNC engraving machine uses digital technology to control the tool or laser head and ultrasonic head for engraving.

TheSculpfun S10laser engraver can be a CNC engraver. The CNC engraving machine can also be equipped with a laser head for engraving, so the two intersect. Let me tell you about the specific differences between laser engraving machines and CNC engraving machines.

Although both use CNC systems, their working methods and mechanical structures are different. In contrast, the structure of the CNC engraving machine is relatively simple. TheSculpfun S9engraving machine automatically selects the appropriate engraving tool through the control of the computer numerical control system, and performs engraving on the X, Y, and Z axes of the machine tool.

According to the specific use, the laser engraving machine is divided into different special machines. The plane structure is basically the same. The laser source emits laser light, and the numerical control system controls the stepper motor of the laser plug to move the laser head, mirror, lens, etc. on the optical components, so that the focus moves on the X, Y, and Z axes, and the material is ablated.

The biggest difference between a laser engraving machine and a CNC engraving machine is that the tool of theSculpfun S30 Pro Maxlaser engraver is a complete set of optical components, while the tool of the CNC engraving machine is a variety of solid engraving tools.

Other differences:

1: Laser engraving and polishing is completed once, and CNC is completed twice.

2: The diameter of the laser beam is only 0.01mm, and the CNC tool is 20 times larger, which is a waste.

3: Laser speed is 2.5 times faster than CNC engraving machine.

4: The energy consumption of the laser is lower than that of the CNC engraving machine.

5: The laser has no noise, no pollution, and high efficiency; the CNC machine tool is noisy and pollutes the environment.

6: The laser is non-contact and does not need to fix the workpiece. CNC is contact processing and the workpiece is fixed.

7: Laser can process soft materials, such as cloth, leather, film, etc.; CNC cannot process because the workpiece cannot be fixed.

Sculpfun S9 Introduction

The Sculpfun S9 is another affordable laser engraver and worthy of consideration if you are looking for a large work area. Its base version starts out with 410 x 420 mm, but there is an optional expansion set to really go ham on truly large DIY projects; up to 950 x 410 mm. The diode laser reaches an output power of 5.5 W with an engraving accuracy of 0.01 mm, making it suitable for cutting and engraving a wide range of materials, including up to 10 mm acrylic and wood up to a thickness of 15mm.

The simple and solid metal frame can easily be assembled within half an hour and is open to further modding down the road. The laser has to be adjusted manually with screws depending on the distance to the workpiece and the machine doesn’t have end-stops, but one of the hidden gems of the Sculpfun is the scale lines on the X and Y-axis. This allows you to get your model’s measurements right as well as align the object properly. Plus, Sculpfun ships a steel pad with the engraver to protect your table from laser damage.

The Sculpfun S9 is compatible with various programs, including the open-source LaserGRBL as well as LightBurn, supports the common file formats, and is compatible with both Windows and Apple systems.

The laser engraving machine can typically be found for around $400. Supersizing with the expansion pack adds another $80 to that. You’re unlikely to find a larger engraver in that price range.

How does a laser engraver work?

How does a laser engraver work? As a beginner or operator, before starting to use the Sculpfun S10 laser engraving machine, you must first understand the working principle of the laser engraver machine, and understand the operation steps and precautions of the desktop laser engraver.

First, we need to understand how the laser cutter and engraver works

The working principle of Sculpfun engraving laser machine refers to dot matrix engraving and vector cutting.

1. Lattice engraving

Dot engraving is similar to high-resolution dot printing. Each time the laser head swings left and right to engrave a line consisting of a series of points, and then the laser head moves up and down to engrave multiple lines at the same time, finally forming a full page of images or text. Scanned graphics, text, and vectorized graphics can be engraved using dot matrix.

2. Vector cutting

Vector cutting is different from lattice engraving. Vector cut outline for text. We usually use this mode to cut wood, acrylic, paper and other materials, and can also mark the surface of various materials.

In addition, we need to understand these 3 concepts: laser engraving speed, laser engraving intensity and spot size.

3. Laser engraving speed

Laser engraving speed refers to the speed of laser head movement, usually IPS (inches per second) means that high speed brings high production efficiency. Speed ​​is also used to control the depth of cut. For a particular laser intensity, the slower the speed, the greater the depth of laser cutting or laser engraving. You can use the laser engraving machine panel to adjust the speed, or you can use the computer's print driver to adjust. In the range of 1% to 100%, the adjustment range is 1%. The advanced motion control system of the laser engraver machine allows you to obtain ultra-fine engraving quality during high-speed engraving.

4. Laser engraving strength

The intensity of laser engraving refers to the intensity with which the laser irradiates the surface of the material. For a particular engraving speed, the greater the intensity, the greater the depth of cut or engraving. You can use the panel of the engraving machine to adjust the intensity, or you can use the operating software of the computer to adjust the intensity. In the range of 1% to 100%, the adjustment range is 1%. The higher the strength, the lower the speed and the deeper the cutting depth.

5. Spot size

The size of the laser beam spot can be adjusted by lenses with different focal lengths. Small spot lens for high resolution engraving. The large spot lens is used for lower resolution engraving, but it is the best choice for vector cutting.

Methods of laser engraving machine cutting 2 common materials

Ordinary mechanical engraving cannot engrave dots of different thicknesses in an economical way, so it does not have a grayscale representation. The laser engraving machine realizes engraving in the way of dots, and has natural advantages in grayscale performance. For this reason, the grayscale expression is used as much as possible in the engraving design. The advantage of this is that on the one hand, the coloring process is reduced and the cost is saved; When the user is using it, first fill the graphics with different grayscales (the text must be converted into graphics first), select the black and white mode for the engraving output, and try the effects of different dots. The accuracy is generally not more than 500dpi. Desktop laser engraving machines are now popular. Although they are small in size, they can basically meet people's engraving needs. The more popular brands are Sculpfun, Atomstack, Ortur, etc. More brands can be found on the HTPOW website.

Wood: Log (unprocessed wood) wood is by far the most commonly used material for laser processing and is easy to engrave and cut. Each type of wood has its own characteristics, and some are denser, such as hardwood, and require higher laser power when engraving or cutting. We recommend researching the engraving properties of unfamiliar woods before engraving. Plywood Sometimes customers may ask you to engrave on plywood. In fact, it is not much different from engraving on wood, but it is necessary to pay attention that the engraving depth should not be too deep. The edge of the cut plywood will also be black like the wood, the key is to see what kind of wood the plywood is made of. Coloring: After wood engraving, there will generally be a burning feeling. It has an original artistic beauty when matched with the wood background color. The depth of the color mainly depends on the laser power and the engraving speed. But some woods are usually softer and you can't change the color anyway (eg: birch). Occasionally a client may ask you to color the finished product, using acrylic paint. Sculpfun S10laser engraver can cut 15mm plywood, 20mm light wood, 10mm walnut and teak, and the cutting surface is very clean with the help of the air-assisted compressor, and it is not easy to carbonize.

Density veneer: Ordinary density veneer This type of MDF is the kind of wooden pallet that we often use as a sign liner. The material is high density board with thin wood grain on the surface. Lasers can engrave on such materials, but the engraved patterns are uneven and black, and generally need to be colored. Laser-specific density veneer This type of density board is specially designed for laser engraving. The engraved pattern has a uniform color and has a good effect without coloring. Cleaning: The MDF surface can be cleaned with a damp cloth after engraving. Filling: Acrylic paint or alkyd paint can be used. When engraving, the color of the graphics can be set to 60% grayscale, so that the bottom surface of the engraving is somewhat pitted to improve the adhesion of the color. The S10 laser engraving machine can cut 6mm MDF boards and even 15mm acrylic, making it a very powerful machine that can meet the basic production needs of small businesses.
