ABSTRACT

Trang 3

3D-printed items are becoming more familiar nowadays The 3D printing system issuitable for teaching and conducting projects in educational settings because of itsversatility and ease of usage.

Moreover, the demand for phone cases has increased significantly in recent years.Customers tend to use a product not only for protective and aesthetic purposes but also tosatisfy their personal intention Our project applies those ideas to design an appropriatecase using a 3D printing system.

The current technology has helped the 3D output goods become more precise, quickerprocessing, and lower cost Therefore, we believe that this method is proper for designingand manufacturing a product.

Sensor sconce is one type of light fixture that is fixed to a solid position, usually awall, It is an old style design which is called wall lamps or wall lights nowadays andruns by electric instead of candles or oil In modern humans add sensors to it so that

Trang 4

they can light up anytime someone gets close to the sconce The average size of thesensor sconce is 34x20x35cm depending on the purpose of the architecture and theowner There is a differential in price for many kinds of sensor sconce Normally, itsrange in price fluctuates between 150,000 VND and 350,000 VND.

Functions: Using the lantern wall sconce not only brightens the atmosphere and does

not glare, but also illuminating the environment does not increase the burden on theeyes The Sconce has decorative effects and special practical value in flashing yourview in any hallway, porch, or outdoor area Therefore, choosing it correctly cancreate amazing visual effects.

Problem statements:

Sensor sconce is currently popular all over the world because of its usefulness Thiskind of lamp can be used for a long time and lasts overtime rather than a traditionallamp running on oil Fixing it may not be easy but people can replace it due to theirsuitable price in the market Therefore, a sensor sconce one is the best choice.

1.3 Systems Requirements

❖THE STRATASYS F370

The Stratasys F370 is the top of the line printer in the F123 series It supports a buildsize up to 14”x10”x14” and it includes support for PC-ABS Materials in addition toPLA, ABS-M30, and ASA The F370 has four material spool bays in an easilyaccessible drawer on the front of the printer Two of the spool bays are used for theprint materials and the other are used for support materials.

The F370 comes with a software license for Stratasys’s Insight software Insightprepares your CAD program’s STL output for 3D printing by automatically generatingsupport structures and extrusions paths This can decrease your print time and cost,and it increases accuracy Through Insight, users can manually edit parameters thatdetermine the look, strength, and description of parts.

Noise Specification 46 dB maximum during build 35 dB when idle

Software GrabCAD Print and Insight licenses

The Stratasys F370 printer has versatile and productive characteristics It allows us toprint from fast and reasonable–price product models to durable complex assemblies.Furthermore, it also provides us with three different materials choices with theeasy–to–move soluble support material From this feature, it can make complicatedparts and assemblies with impressive accuracy, details, and repeatability

The Stratasys F370 printer also works more effectively compared to the previousprinters F170 and F270 It has an all-new fast–draft mode to create the initial designconcept cheaply and quickly so it is easier to print twice as fast as standard build modewith only one–third of the average material With PSA materials utilization, it is moreefficient and economical because PSA provides the speed of fast–draft mode andminimizes the material expenses simultaneously.

Besides, the Stratasys F370 printer can give us exceptional values with its expandedcapacities and unprecedented accessibility Moreover, with new–developed features,this printer enables us to save our time and budget, print quietly and smoothly.

1.3.1 Uses

For the printer to work, it is important to control it on by principally associating withthe power attachments and squeezing the Power button situated before the printer,after which choosing "On" and changing a few essential settings From that pointforward, we want to plan, introduce, and load the material spool to choose theappropriate materials for framing items.

Before the printer can conduct well, we need to set up the machines: First, we need todownload files to the printer and then load separate job files to the Job Queue byselecting one over two ways:

1 Application of the GrabCAD Print by connecting the network to workstation PC.2 Utilization of USB by inserting a USB drive flash into an available USB port.

Trang 8

Second is to prepare for the printer before we start to print so to operate the printerfor a build, we need:

- Turn on the printer- Open the oven door

- Place a new substrate onto the platen and lock the substrate into its build position bylifting on the substrate ejection handle.

- Ensure that the tip wipe assembly’s brushes, as well as the printer’s tips, are cleanand that the purge area is free of purged material debris.

After completing all the steps from the setup process, we should follow the belowsteps to print our 3D products:

❖Step 1: Fill in the Job Queue and choose the Queue button within the NavigationMenu After that, we will see the Queue page opened to display the Job ❖ Step 2:

When the Job Queue list appears, arrange the job to build in the necessary order and

select by touching its row on the screen to open its Job Details page ❖ Step 3: On the

Job Details page, press the Print button to queue the job for printing A dialog willappear based on different part placement setting configurations.

- In the event that the Enable Part Placement setting is turned On, we can pick a task'sarea on the substrate with the authorization of a shown discourse, so we need topick the work's fabricate area by dropping the jumping box on the touchscreen.Subsequent to finishing this decision, press the Print button in the discourse toaffirm the picked position and begin the build process.

- If the Enable Part Placement setting is turned Off, the job will automatically be builtin the center of the substrate regardless of a displayed dialog.

❖Step 4: When the Build page opens, the types of material for our selected job will

decide the heat to a set point temperature for the oven operation

❖Step 5: After the oven and liquefier tips reach the desired temperature, the printer

will perform a Z Zero Calibration When this calibration happens, the word“Preparing” appears in the Build Status Display.

❖Step 6: Once Z Zero Calibration is finished, then the printer starts building the job

with the word “Building” appearing in the Build Status Display while it isoperating This step allows us to print our products.

❖Step 7: After completing the printing process, the text will appear on the

touchscreen, which means the printer can remove the finished printing part.

1.4 Scope and Limitations

1.4.1 Scope

Our product is a light sensor sconce with a modern European style, with originalstraight lines without patterns, it can be placed in the main door in the hallway, stairs,companies, hospitals or places that need to provide constant light with the light sensor.We can rest assured about the lights on and off in the areas outside the house Theproduct is widely used with a low price that can be easily accessed by everyonebecause it is safe for all ages, does not have to have much contact with the switch, andis easy to assemble.

➔Do not install near electromagnetic transmitters or objects that vibrate, shake andmove because it affects the operation of the sensor.

● Sensor range:

➔ Sensor lamps have different scan angles depending on the input receivertechnology used and the manufacturer's design The sensor angle is the area wherethe sensor can receive the signal And any changes that occur outside the scanningangle will not be detected by the sensor

There are three main parts: the top of the light cover - the canopy, the reflector, thecandelabra including the light fitting and the kickstand.

● The canopy: There are many layers stacked from top to bottom, which are small tobigger respectively, connected to the transparent body of the lamp.

Figure 6: The top of the Light cover

● The reflector: We use mica to fill this blank In total there are six surrounding facesforming a hexagon Transparent material can help the light get through easily.
