What Should We Pay Attention To In The Process Of Model Design For 3D Printing?

No matter which 3D printing technology will be adopted, we need to pay attention to some

issues when designing the 3D model.

For different 3D printing technologies, there are specific design rules that need to be remembered and adhered to. This article only discusses general design considerations applicable to various technologies.

Printability is a very important thing to keep in mind when designing 3D models. The process of modeling will really change the digital models into physical objects.

In the simple design process, there are no physical laws that need to be observed, such as gravity or the expansion and contraction of printing materials.

1. Draping

Draping means that the printing part is supported by the lower layer, or without support at all. All 3D printing technology is based on superposition manufacturing, that is to say, the printing layer should be combined with the following layer (except SLS and jet technology). FDM printing technology limit angle of 45 degrees, less than this angle need to add support to ensure accurate printing.

2. Wall Thickness

The second problem to be considered in the design of 3D model is wall thickness. In order to print another layer on one level, it is necessary to determine the minimum wall thickness that can be printed, depending on the specific technology employed.

For example, suppose you are a glider design engineer, and you have a great and innovative design plan to use 3D printing for small-scale testing. The modeler will model the thickness of the canvas on the wing, but because the thickness is too small, it will not be printed when printing.

3. Warp

In 3D printing, some phenomena are often ignored, like SLS or FDM technology. In order to heat the material to 200 degrees C, the heating and melting of the material may lead to warping. A long flat surface is very easy to deform, and the machine is calibrated to maintain enough adhesion between the parts and the building platform to avoid warping effectively. Your Hub gives a lot of design techniques to reduce the possibility of warping.

Desktop 3D printer consumables include: Small SLA, DLP photosensitive resin material, PA12 nylon powder, polymer plastics ABS, peek, renewable PLA bioplastics, extremely flexible, high strength and high hardness carbon fiber composite consumables, high transparent glass like P-glass, food grade heat-resistant pp-pe, l-pa elastic low temperature nylon, conductive nylon conductive, antistatic nylon nylon nylon a Nti0static, flame retardant nylon nylon flame retardant, luminescent ABS, fluorescence, light change, temperature change, luminescent PLA, PP polypropylene, PC polycarbonate, PETG have high mechanical strength and excellent flexible luster transparent, bamboo wood wood consumables, gold plating, silver plating, red copper, bronze metal PLA consumables, hips modified polystyrene soluble in organic solvent, which can be used as a printing agent Support material.

PLA:Poly Lactic Acide,aka corn starch resin,whihc is know as PLA is totally made of plants of corn or sugar beet with the procedures of fermentation, dehydration and polymerization. It is environmental friendly that can be 100% degraded. Besides, based on the normal PLA adn miantaining the high strength of it, we also develop High-tenacity PLA to solve the common problem of a lack of tenacity.

Q9. Solution For The 3D Printer Feeding Problems

Many people are at a loss when they encounter the problem of 3D printer filament feeding. Now I has collected some common problems and listed some solutions for reference.

Feed:

A.Please make sure the 3D printing filament end is flush rather than sharp, straight rather than curved before the filament insert into feed inlet, And then inserted into the filament inlet vertically.

B.When the 3D printing filament is not used for a long time, please put it in the packing box or in a dry and ventilated place to prevent it from getting damp and deterioration.

The extrusion out filament is very thin:

A.Check whether the display screen is heated to the preset temperature; confirm that the printing filament has entered the feed inlet, and insert it again after pulling out.

B.Find the screw beside the 3D printer extrusion nozzle motor, turn it anticlockwise with the hex wrench, and then see the thickness of the 3D printing filament.

C. Press the aluminum block beside the extrusion nozzle motor with your left hand, And then grasp the printing filament with your right hand, and push it into the feed inlet. The thickness of the extrusion out filament can be seen.

D. After heated,pull out the printing filament, disassemble the extrusion nozzle, clean up the debris near the feed inlet with a brush, and then feed thefilament after assembly again.

If the 3D printer extrusion out filament still can not be discharged smoothly, please replace the extrusion nozzle.(please always keep the nozzle in the state of heating when you are solving the filament feeding problem, )

Leakage Filament:

Phenomenon: the top of the extrusion nozzle is full of the molten printing filament.

Cause: the feed tube and heating block do not fit tightly.

Solution: The 3D printer printing extrusion nozzle needs to be equipped with the material belt and reassembled.

Q10. What Are The Characteristics Of 3D Printer Printing Material Promatte?

Promatte is a research and development achievement jointly developed by type a machines, an American 3D printer manufacturer, and polymeker, a 3D printing wire developer. Its special feature is that due to the matte treatment of promatte itself, the model printed with this wire does not need any post-processing, because it will cover the layer texture in the manufacturing process of FDM additive. Of course, if the user needs to post process it, according to the company, promatte is very easy to polish, whether it is carving or other processing, it is very convenient.

Based on the premise of strong toughness and flexibility, promatte is also 30% lighter than the standard PLA filament. According to the company, this feature also meets the requirements of printing light models of complex structures. It is reported that 3D printing wire promatte has a diameter of 1.75mm, a weight of 500g per roll and a length of 230m, while the standard PLA filament only has an average of 165m per roll. At present, consumers can buy the 3D printer printing filament through the online mall , The unit price is $58. There are two options: matte black and ivory white.

Q11. How can the plant plastics be used in 3D printer printing?

3D printer manufacturers are focused on developing new 3D printing materials to meet high-strength modeling requirements and improve the surface finish of models. At present, in terms of widely used 3D printing materials, plastic has the largest share in the global 3D printing material market, and the demand for electronic products and consumer goods is increasing, which is expected to further promote the demand of plastic as 3D printing materials.

Recently, plant plastics have become a very popular choice for 3D printing at the international level, because this material is easier to process and more environmentally friendly, but due to its low softening point temperature, petroleum plastics are still widely used. However, the market prefers vegetable plastics to petroleum plastics. Bioplastics, in cooperation with 3DOM, has developed a biodegradable thermoplastic biome3d, which is a biodegradable plant-based plastic. There is a very high surface finished by 3D printer printed product , And can reduce brittleness, make the product more flexible and not easy to warp and crack, has a lower shrinkage and no smell.

This further provides the possibility that plant plastics can replace petroleum plastics in an all-round way.

Q12. Defects Of STL Format In The Process Of Conversion That 3D Printer Printing File Format

The conversion of STL file format is an important problem in the process of 3D printing. In the last article, we introduced several problems that need to be paid attention to in the conversion of STL format, in order to help you better carry out the format conversion and subsequent printing work. In today's article, we may as well look at the defects that will exist in the process of format conversion. These defects need to be avoided to ensure that there are no difficult technical problems in printing.

The following problems may occur during the conversion of STL Format:

1. There is a gap, that is, the loss of triangular patches

This kind of defect occurs when triangulating the intersecting parts of high curvature surfaces. On the displayed STL format model, there will be incorrect cracks or holes (there are no triangles), which violates the rule of fit. In this case, a number of small triangular patches should be added along these cracks or holes.

2. Distortion occurs, i.e. all sides of a triangular patch are collinear

This problem usually occurs in the conversion algorithm from 3D solid to STL file. Because triangle patches are produced to different entities at the intersection line, the distortion of triangle patches at the intersection line will be caused.

3. The triangular patches are overlapped

The overlap of patches is mainly caused by the rounding error of the numerical value when triangulating patches. The vertices of triangles are represented by floating-point numbers in 3D space, not by integers. If the rounding error range is large, it will lead to the overlap of patches.

4. Topological relationship of ambiguity

According to the common vertex rule, there are only two triangles on any edge of the model. If there are more than two triangles sharing this edge, there will be ambiguous topological relations. These problems may occur when triangulating planes with sharp corners, intersecting parts of different entities, or generating STL files.

Because of these defects, we must check the validity of STL file data in advance in the printing process, otherwise, the STL file with defects will lead to many problems in the processing of 3D printer printing rapid prototyping system, such as geometric distortion of the prototype, etc., and even crash in serious cases.

Q13. The Notes That the 3D Printer Printing STL Format File Is Being Generated

In the process of 3D printer printing, you will have a very important step, which is to convert 3D design files into STL format 3D model files. A STL file is generally defined as a series of triangles to define a 3D model, so it includes the normal and vertex XYZ coordinates of all these triangles. If there are too many triangle definitions in this STL file, then this file will be too large and will not be a qualified file. At this time, some experience will be used. This article will share some questions about STL file transformation steps.

1. Common vertex rule

Every two adjacent triangle planes can and can only share two vertices. The vertex of a triangle plane cannot fall on the edge of any adjacent small triangle plane.

2. Orientation rules

The normal vector of the plane of each small triangle must be outward, and the vector formed by three vertices shall be determined according to the right-hand rule (the order of counterclockwise rotation). Moreover, there is no contradiction of orientation in the adjacent small triangle plane.

3. Value rules

The vertex coordinate value of each small triangle plane must be positive, negative value and zero will cause failure.

4. Full of rules

There shall be no omission on all surfaces of the 3D model, that is to say, all surfaces of the 3D model must be covered with small triangular patches.

5. Euler formula

The number of vertices, patches and edges in the 3D Printer Printing STL file must conform to Euler formula.

Q14. EOS Launches A New Laser Sintering System P500:Double Output And Reduce Cost By 30%-- That 3D Printer Printing Material

Germany's industrial 3D printer manufacturer EOS announced that it will soon launch a new polymer additive manufacturing series. Its first product is the P500 laser sintering system. The p50o system consists of four modules and an external station. The internal design adopts modular design, which provides the possibility for future 3D Printer Printing Material updates.

Q15.Why 3D printer printing caused the edge warping problem ?

Edge warping refers to the upward bending of 3D printing on the basis of the model, not on the same horizontal line as the 3D printer printing platform. Edge warping is caused by the natural characteristics of plastics material. Because of the cooling of PLA or ABS fiber, the plastic begins to contract naturally which is very slight. So one of the reasons for the3D printer printing edge warping problem is that the plastic cools too fast.

Q16.What materials are common used for FDM 3D printer printing technology?

The materials often used in FDM 3D printer printing include: engineering plastics (PLA and ABS), flexible materials (TPE / TPU), wood sense materials, metal PLA / metal ABS, carbon fiber materials, glow in the dark materials, etc. Different materials can be used to make different types of 3D printer printing models and components, but also have their own advantages and disadvantages.

Q17.How is the nylon 11 used for 3D printer printing?

Nylon 11 chemical name is Polyundecylamide (biological base material) and can be used for FDM 3D printer to print soft products, such as swimwear. Because its flexibility is not damaged in the printing process, and because of its high density, it can also meet the need of water-proof swimwear.

Q18.How to apply the PCL in 3D printer printing?

PCL is mainly used in FDM printer printing in 3D printer. Because of its low melting point, it does not need a high printing temperature, so as to achieve the purpose of energy saving. At the same time, because of its low melting point, it can effectively avoid scalding during operation. At present, people in the industry are hoping to make children's 3D printers with this feature. In addition, because of its shape memory feature, it makes 3D printed things have "memory" and can be restored to the original set shape.
