Coffee cup with coffee beans engraving

prusaprinters

<p>This is a coffee cup with an engraving of coffee beans on two sides. The cup is about 95mm tall overall and has a capacity of 335mL.</p> <p>Obviously, make sure your material is food grade if you intend to drink from it. I used certified food grade PLA and heat treated it so it would stand up to hot coffee and dish washing. Also, if you want to be 100% safe you should use a stainless steel nozzle, as some brass alloys contain a small proportion of lead. Personally, I think the quantity of lead that could possibly make its way into a single print is quite low, and I don't intend to make a big habit out of printing food containers. I wouldn't go printing all my cutlery and kitchen utensils with a brass nozzle though.</p> <p>Heat treating as a general rule will cause some warp so be warned. Though if dimensional accuracy is your priority for a coffee cup you might have something wrong with you.</p> <p>Print settings:</p> <p>I used a brim to aid with bed adhesion as the contact surface area is fairly low. The bottom of the cup is domed, and will require support under it to print properly. I used support blockers to stop supports generating under the engravings (because the cup is curved, they are somewhat over the build plate). I recommend printing at 100% infill, as solid parts tend to warp less when heat treating.</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Creality</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>Ender 3</p></div> <p><strong>Rafts:</strong></p> <p>No</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>Yes</p></div> <p><strong>Resolution:</strong></p> <p>0.16mm</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>100% for minimising warp</p></div> <p><strong>Filament:</strong> 3DFillies PLA - heat treated after printing Blue</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>Supports are needed under the bottom dome. </p></div> </p></p></p> Category: Kitchen & Dining
