"Well done is better than well said. "
- Benjamin Franklin
3D printing is a process of manufacturing three-dimensional objects with the help of a 3D printer. In this, different materials like liquid, powder, plastic, and other filaments are added layer by layer. Hence, it is also called Additive Manufacturing.
With the help of computer-aided design and other printing technologies, 3D models are developed for the desired product.
Whether you’re new to 3D printing or have a bit of experience, there are certain problems that you face with 3D printing.
To save your time and help you establish your 3D printing business successfully, we have come up with solutions to the commonly faced problems with 3D printing.
Common 3D printing problems and ways to avoid them
3D printing is not as easy as it sounds to be, in fact, it’s one of the most complicated techniques. A small mistake can ruin the whole part or prototype.
The 3D printing industry is evolving with time and many kinds of materials are introduced for use every once in a while. It’s important to know what kind of material is the best fit for your 3D product.
3D printing goals are different for everyone. You have to decide whether you want to print a solid or flexible object and the colors you would like to use.
Based on your goal, you need to find the appropriate 3D print design. If you choose the wrong design, then the materials will be of different quality altogether.
That’s why it’s important to select the right material and follow the design guidelines of that particular material.
It will save you a lot of money and time.
3D Print Stringing
3D print stringing is the most common challenge that people face when printing something using a 3D printer. This happens when the melted plastic is oozed out of the nozzle while the printing equipment is moving from one end to the other. It’s more like a normal printer, where you see the leakage of ink at times.
The material or plastic solidifies and it gets difficult to get rid of the extra strings during the post-processing method.
You can avoid this problem by enabling retraction. When you do this, the filament that is inside the nozzle is pulled back and is stopped from moving.
Additionally, you can also increase the retraction speed as it will decrease the chances of stringing. Also, the distance of retraction matters, make sure to choose a far distance for retraction to avoid stringing.
3D Print Warping
Warping of parts occurs when the deposited material starts cooling during the printing process. This uneven and untimely cooling causes deformation of parts resulting in a defected object as an output.
How can you avoid this problem?
By using a heated print bed you can increase the time it takes for the layer to cool down when it is deposited, thus it saves the filament from warping.
Also, you may build surface adhesion as it will help with other filaments like glass or aluminum. Make sure to keep the build surface clean all the time.
3D Print Pillowing
3D print pillowing occurs when holes and deformities form in the topmost layer of the object that is printed with a 3D printer. It happens because of improper cooling as the top layer fails to get enough air to cool properly. Pillowing can occur with any filament.
The only way to tackle this problem is to set a thick top layer and adjust the cooling. Ensure that the cooling fan is working efficiently.
3D Design Software
The simple drag and drop option in 3D design software makes the designing process look effortless. However, creating a proper 3D print design takes knowledge, time and effort.
So, it’s important to learn different tools or 3D designing software that is used to make the design.
Without jumping right in thinking it’s easy, take your time and first learn the basic design concepts.
Just like any other skill, 3D printing too is learnt over time as it’s an ongoing process with myriad changes every now and then.
If you’re just starting, try it with small objects that are less costly. With time, you can gain experience in 3D printing and scale your business.
